What to do if the buttons do not work on the laptop keyboard

What to do if the buttons do not work on the laptop keyboard

We tell, because of which the keyboard in the laptop may not work and how to fix it.

Being a basic means of entering information in a computer, the keyboard is indecent often breaking even in new devices. And under "break" I mean a long list of problems associated with keyboards. From the banal sticking of dirty keys to serious program errors.

Actually, about everything about this further and talk.

Causes of keyboard breakdowns and solutions

We will analyze the main problems and ways to solve them.

Immediately I want to note that sometimes a small bug pops up in the system, that is, an error that interferes with the normal operation of the keyboard. I call him small, because it is neutralized by the usual reboot. Before making any serious actions, restart Windows.

And now we went.

Manufacturing defects

Let's start with the fact that the "breakdown" in the keyboard can be discovered immediately after buying a laptop. That is, someone drew it even at the assembly stage or during transportation. It rarely happens, but it happens. The laptop hit somewhere, or on the assembly stage, the item was unsuccessful and so on.

Because of this, the keyboard can work incorrectly. It may not be pressed in some places or to stick to the body. Send an incomprehensible crunch. Or it can be quite normal to click and quite naturally felt, but the system will not respond to the interaction with the keys.

In general, if you notice something like this when you first turn on the laptop, then immediately go back to the store. This is a 100% warranty case, and you can replace your computer or at least return money for it.

For warranty, the goods can be returned for one year (if the store clearly does not indicate the reverse). Apple computers for two years. But in any case it is better to hurry. If you do it in the first two weeks, everything will go much faster and without unnecessary turmoil.

"Pilot" buttons

Under the "sticking" literally implies temporary jams of keys in one place. That is, you click on a specific button, it calmly makes the move, but it does not return to its original position. Naturally, because of this, it is impossible to press her second time. At least immediately.

As a result, the swollen keys lead to a bunch of typos in the text, to a huge amount of extra letters and launch of the commands that the user was not going to activate. We will understand where the "sticking" comes from and how to deal with him.

From food

First of all, this kind of problems with buttons arise due to physical garbage. I called this block of article "from food", because those who love to eat behind the laptop are much often littered by the keyboard. But this does not mean that another small garbage (such as fat and dust pieces) cannot be jamming individual elements of the keyboard.

In this case, only cleaning will help. It is necessary to purchase a compressed air cylinder and spray it at an angle to the laptop housing in the keyboard area. The strong pressure of the incoming air will push the entire sticking garbage and dust. And the keys will no longer interfere normally move.

Apple even made a step-by-step instruction when he released laptops with their new, terrible, ever with a sticking keyboard.

Apple recommends first tilt the device
Apple recommends first tilt the device
Then walk with compressed air along the keys
Then walk with compressed air along the keys
And then across
And then across

If the cylinder does not help, you can remove the keys (if it is provided for by the design of the keyboard) and wipe the area under them with a dry tassel.

On some laptops at the top of the keyboard there are small "tongues" to quickly extract the keyboard from the case.

From imperfection of assembly technology

The second cause of "sticking" is an ill-conceived keyboard design. From this for a long time, Apple laptops suffered. Their butterfly mechanism for individual keys turned out to be so non-donuticated that he ventilated literally because of any dust. And sometimes the buttons were stuck forever.

In this case, you need to refer to the manufacturer. Most likely, you will provide free repair or keyboard replacement. At least in the case of Apple.

Spoiled microcircuits

Under the keyboard there is a microcircuit that transmits a signal from each pressing to the system. If it is damaged, some pressures may not be read at all or read incorrectly (with a delay, with errors).

Damage options can be a lot. Some contacts burned down, the keyboard was poured with water, in the layer between the keys and the board, too much dust was formed and so on. A bunch of unsuccessful scenarios.

So the keys look at the printed circuit board
So the keys look at the printed circuit board

In any of them, it will not work out without opening a laptop.

  • First we are looking for two special levers in the upper or lower part of the keyboard and give them to completely remove the keyboard unit from the case.
If there are no levers, you will have to turn the computer and first unscrew the fastening bolts that hold it in the assembled form.
  • Then we uphold the keyboard unit from below to access microcircuits.

Under the keys, you will see a fee or a steel plate with contacts. Carefully inspect it and we are looking for hints on flaws.

  • We wipe the dust with a dry cloth (if the keys are triggered alternately or react with the delay).
  • We remove moisture if there is such.
  • We remove the extra garbage.
  • We are looking for traces of fire and other physical damage.
  • Check the tester non-working tracks of contacts. We find those that do not give signs of life, and re-"draw" them with the help of conductive glue.

In the case of entering the water key (tea, cola), it is best to refer to the specialists. Most likely, the keyboard will not be able to save, and have to perform much more complex repairs. There are professionals.

Damaged loop

Another common physical damage. The keyboard is connected to the motherboard of the laptop with a flat cable (loop). If you break it up, spend, stretch, pour, then some keys (or all together) can fail.

This is especially often happening after handicraft. When a person decided to look at the inside of the computer, I wanted to change something there and I accidentally pulled out for the train, damaging it.

Usually, this kind of thing is visible to the naked eye, but it is not always the case. In the case of a spoiled loop, you will have to refer to the specialists who can replace it with a new one. Repair it is most likely meaningless.

Oxidations can be formed on the loop contacts. They can be tried to remove them with an eraser. That is, carefully erase, not pressing and not making a lot of effort. Such a repair is even an amateur, but something is more seriously better to provide masters.

Software failure

Now go to the problems that will not be able to identify and eliminate physically. We will talk about errors in software and some features of the interaction between Windows and the laptop keys.

Blocked keys

This will be discussed at once about two types of software blocking buttons:

  1. Blocking the entire keyboard. This feature corresponds to a separate physical button or lever. It is either above the keyboard, or on the device's end, or in one row with keys F. And sometimes it can be blocked by a combination of buttons. Type Function + Win. . It all depends on the device model.
  2. Block blocking with numbers on the right side of the keyboard. The Numlock key is responsible for the work of this area. If you click on, the numbers on the right will earn. If you press again, it will stop.

Carefully follow these two buttons (or buttons combinations). Often it is that they cause a complete shutdown of the keyboard or part of it.

Lack of needed software

Typically, no additional drivers are required keyboards. Windows copes well with their installation in automatic mode without the need for a user to download something alone. Nevertheless, the software that is responsible for operation of the keys can "Talk". In this case, we do the following:

  • Reboot your computer.
  • At the early trigger stage, press and hold the key F8. .
  • In the menu that appears, see the "Safe Mode" item and choose it. So we will run Windows without drivers and can check how the keyboard functions without them.
  • When the system starts, start testing all the previously promoted keys. If nothing has changed - it means that the problem is not in software, but in the "hardware". Continue diagnostics. And if the buttons earned, then go to the next step.
  • Open the program to execute commands by simultaneously pressing the keys WIN. + R.
  • We enter the text there Devmgmt.smc. And click on the "Enter" key.
In the same menu, you can get through the classic control panel
In the same menu, you can get through the classic control panel
  • In the window that opens, the keyboard item that opens and click on the arrow to the left of it.
  • A list of all available keyboards will appear. We choose the one that worked incorrectly, and by clicking on it right mouse button.
  • In the context menu that appears, select the "Update Driver" item.
What to do if the buttons do not work on the laptop keyboard
If the system refused to search and install new drivers, you can try to completely erase it. To do this, we do all the steps described above, but at the end you select the "Delete device" item. And then reboot the computer so that the system is faced with a new device without drivers and tried to re-configure it.

That's all you can do in this area.

Virus

The most unpleasant thing that can happen to the system is a virus infection. Malicious programs can make a bunch of packages during Windows. Many of them can take control of the keyboard. Block individual keys or temporarily disable them all. There are dozens of options for inadequate behavior of an infected code. You can deal with it only with the help of special software.

Do not be lazy and download yourself one of Free Antivirusov For Windows. It is likely that even he will cope with the search and removal of the contagion, which can affect the keyboard operation.

More couple of tips

If the virus search also did not help, but it seems to you that the problem is in the program part, you can try to completely reset Windows to factory settings. It will delete all the content, all non-working drivers and malware.

To make sure that the software failure is software, and not a hardware, you can connect to the USB keyboard laptop and see how it will behave. If it is necessary to work adequately, it is possible with a 99% confidence of jam on the hardware.

Good times day!

If there is no problem with a conventional keyboard for a PC, it broke, bought a new one, then with laptops not everything is so simple:

  • First, it is enough to find it in some cases;
  • Secondly, it is not easy independently to change (sometimes it is necessary to disassemble all the device);
  • Thirdly, not always the inoperability of some keys is related to the malfunction (and on this, many users are burned down ...)!
  • Fourth, the keyboard of the laptop is often "biting" at the price (it is much more expensive).

Actually, in this article I want to give some of the exact reasons, because of which the keys can stop. In addition, it is not always worth running at the new keyboard immediately - you see if you do not work 1-2 keys (which are not so often used), then you can quite do without them?

In general, in this article I will give various options for the causes, solutions, and what can be taken if you encountered this problem. So…

What to do if you do not work some keys

Whether keys are turned off in BIOS (relevant for Fn, F1 ÷ F12)

If you do not work function keys ( F1 ÷ F12. ), either special. key FN. - It is possible that the problem lies not in the keys themselves, but in the BIOS settings (UEFI). By the way, I note that by default on many laptops, the function keys are disabled (Instead, excellent functions are performed: add volume, on / off. Wi-Fi, screen brightness adjustment, etc.) .

As a rule, you must enter the BIOS and change the mode of operation functionality. keys (the name of the parameter something like "HotKey Mode", as in the screenshot below).

HotKey Mode - Modified F1-F12 Key Mode

In addition, pay attention to whether you have drivers and specialized software from your laptop manufacturer. To automatically update the drivers, I have long recommended this list of utilities: https://ocomp.info/update-drivers.html

Why may not work Fn and F1 ÷ F12 function keys on a laptop (solution solving) - https://ocomp.info/funktsionalnyie-klavishi-i-fn.html

By the way, if you have a regular keyboard for PC - then pay attention to the special keys F Lock. or F Mode. (eg). They are not so often, but still ...

Using them, you can turn off the function keys (next to them, usually there is a LED, an example below).

F LOCK key (most often found on expensive keyboards)

Trash under the keys (dust, crumbs, hair)

Most often, the cause of a bad triggement of most keys is garbage and dust, which over time accumulate under them. A characteristic feature in this case: with a weak press, the key does not work, however, when you press with some effort - the key works. Although, of course, much depends on the design of the keyboard itself (some are specially protected, and such a problem does not have such a problem).

In any case, from time to time I recommend to clean the keyboard from the garbage (it will not be too much).

How can I clean the keyboard:

  1. Method number 1. : Use compressed air cans, which are sold in most computer stores (or by a conventional vacuum cleaner, turning on the reverse mode). With the help of such a simple "blowing", you can get rid of most dust and crumbs from under the keys.

    Squeezing

  2. Method number 2. : Now in many stores (for example, Chinese) sold specials. Keyboard cleaning vacuum cleaners. Also a very good and convenient means (an example of such a device - see photo below).

    USB keyboard vacuum cleaner

  3. Method number 3. : Also in many stores now there are "spreading" velcro. The principle of working with it is quite simple: first you put it on the keyboard, slightly attach it - it spreads and fills all the emptiness between the keys, all dust and debris sticks to it. Then replete it along with the garbage.

    Velcro for cleaning the keyboard

  4. Method number 4. : If you have a regular keyboard (not a laptop) - you can simply turn it over and knock on it slightly, shake. Even this way helps to "knock out" a lot of too much of it ...
  5. Method number 5. : If you are a little familiar with the technique, you can try to disassemble it and blow from the inside, manually wipe and clean (I note that the operation requires some experience; do at your own risk) .

Wear and boiling tracks (especially relevant when the keyboard is influence)

For reference! Conditionally keyboards can be "split" by 2 camps: membrane (in which thin films are used with tracks), and mechanical (where each individual button is "button"). The most common keyboards are membrane (about 90% -95% on the market). They are cheaper and easier (which is especially relevant for laptops).

So, no matter how the keyboard is - it is designed for a certain number of presses (as a rule, several tens of thousands are several years, even with active use). Over time, the conductive tracks are skidding, thin contacts, closing tracks, wear out, also makes their "case" and dust.

By the way! The process of "crying" conductive tracks is accelerated hundreds of times if you spill some fluid on the keyboard. What, by the way, not so rarely, the specialists abroad considered that every 100 mug above the keyboard overthoe on it ...

The membrane keyboard (as an example, to understand what it was about).

When problems with the old keyboard (either with a flooded, some kind of liquid) I can advise the following recipe (He does not guarantee recovery, and do it all on his own fear and risk. However, a few keyboards revive for a while, he helped me) :

  1. first remove (turn off) keyboard from a laptop (from PC);
  2. If the keyboard is filled with some kind of liquid (lemonade, tea, etc.): well rinse it in warm water with a detergent (for example, Fairy) and let it dry. Connect again and see if it began to work normally;
  3. If the option does not help, you will have to completely disassemble the keyboard, and wipe the film with tracks and the elastic membrane using ethyl alcohol.
  4. Pay attention to the state of the tracks: if there is somewhere suspicion that they "exterminated" or damaged - they need to be treated with a conductive glue (it would not be "ringing" the track to determine whether it conducts "signal" / current); Or simply accept and buy a new one ...

    Example of keyboard track repair

  5. The method of though "collective farm", but sometimes helps to restore the keyboard. By the way, it is suitable only for the membrane type of keyboards.

How to do without some buttons

It is not always possible to replace the keyboard: sometimes it is trite there are no funds, often many get used to their keyboard that simply do not want to change it to any other. As for laptops - it can be so to become that the desired keyboard can not find the desired keyboard ...

But in many cases, you can do without non-working keys (especially if there are only 1 ÷ 2). The most popular ways of this "bypass" will give below ...

You can reassign one key to another

The most common option is to use special utilities that can be replaced by pressing one key to press on another. Sounds a little "strange", but the principle is:

  • Does not work with you, say, key "z";
  • You install the "Ctrl" key together;
  • Now, when you click on "Ctrl" - you will have to work "z" (I draw attention that you can reassign almost any buttons with each other).

MapKeyboard: Only three actions to replace the keys (clickable!)

I personally implies the MapKeyboard utility - simple, free, reliable. The principle of working with it is very simple: first indicate which button you want to use instead of non-working; Then you specify not working and save the settings. After restarting the PC / laptop - "Case" is done, the key will be replaced (the screen is slightly higher).

You can connect an additional keyboard

Also, like the PC, you can connect a regular keyboard to any laptop (most often the classic USB keyboard is used). As a rule, there are no problems with the setting: the keyboard becomes available for work immediately after connection.

As an example (a USB keyboard is connected to a laptop)

You can use a virtual keyboard

Not everyone turns out to know that there is a virtual (software) keyboard in Windows, which can be pressed the mouse cursor. Something like that that appears on Android devices when you contact some text block.

To invoke such a virtual keyboard, open the Windows Control Panel and go to the next section: Panel Control Special Opportunities Special Opportunities . There will be a link to its launch (see screen below).

Turn on the screen keyboard

The keyboard looks quite well, the buttons are large, convenient. It can be used when filling small text fields when the main keyboard does not allow it to do.

Screenshot of the screen keyboard

Addition!

By the way, in some cases (for example, when a specific key does not work, say Print Screen to create screenshots) - in most modern applications you can easily change Hotkeys By default, those that you need (i.e. was Print Screen to create a screen - the Ctrl + Shift combination was a combination). More details here: https://ocomp.info/ne-rabotaet-print-screen.html.

If the problem is with the power button

Not so long ago, by the way, received one interesting question about the non-operating power button (POWER) on the laptop. In general, it does not apply directly to the keyboard, but nevertheless ... I decided to specify it, too, in this article.

The reasons for which the buttons on the laptop do not work can be a lot. All faults belong to either a hardware or software. We will analyze the most common causes of keyboard failure. We will analyze how to behave in a situation where the laptop spill a liquid.

Do not work buttons on a laptop - we are looking for reasons for the cause

The solution of the problem always begins with the search for the causes of its occurrence. The reason may be a hardware type, when the keyboard was damaged physically and software, when the buttons cause is an error somewhere in a virtual environment.

It is necessary to make a small diagnosis to approximately understand what happened. To do this, you need to check which keys do not work.

  • All keys do not respond;
  • Sticks part of the keys;
  • Only some buttons do not work;
  • Does not correspond to the digit block on the right;
  • Everything is completely not working, including indicators.

Such an easy-to-first diagnostics will help determine the further action on the fixing of the keyboard.

Does not respond to the commands right block numbers

Here you can immediately write a solution. Usually above the number "7" is the so-called function key "Numlock".

Her pressing blocks all the numbers in the right block. The fact that it is active is evidenced by a special indicator, but since there are no indicators on new models, you can only check it out, and then try pressing the numbers from the block.

Sharp keyboard keys

Under the shaking keys in this case, there is a long response or no reaction after one press as a result of the accumulation of garbage under the keyboard.

Damage to tracks

If, after scratching the keyboard panel from the garbage, some buttons on the laptop do not work anyway - it means there is a serious problem, namely, damage to the board tracks.

Software reasons

As for the program part, then the keyboard failure may be due to the fact that the driver has been removed for any other reasons. The second most frequent cause is a virus on a computer that can damage the software components of the keyboard.

Contact Oxification for keyboard loop

Everything is connected to the main or motherboard with a wide loop. Throughout the loop, there may be contacts, and they can oxidize, with time or as a result of the fact that the keyboard was shed liquid.

Refusal of the keyboard board

The keyboard board consists of several microcircuits, which are interconnected. Spilled liquid, mechanical impact or adverse storage conditions of a laptop can lead to oxidation of contacts or in general to the full failure of the board.

Laptop buttons do not work - troubleshooting

Immediately after clarifying the circumstances, the breakdown can start repairing the keyboard. If you are not a confident user, and you are not used to working with computer components - do not experiment! Contact the service center. Popular repair can cause even more problems.

Keyboard repair on software or hardware level does not require special skills and knowledge. Unless of course it is not damage to chips or the entire board.

Cleaning the keyboard from garbage

Sooner or later, the keyboard begins to pollute. Depending on how she enjoys the laptop owner: how often he eats behind him, as often he is removed in the room, where there is a laptop. With a high degree of pollution and start problems with the buttons sticking.

In order to clean the space between the buttons and the following will be required:

  • Special brush for cleaning hard-to-reach places - gaps between the laptop housing and keys;
  • Vacuum cleaner, sprayed aircraft or hairdryer;
  • With a strong need, the cross screwdriver of small size and flat of any size, but not too large.

There are two ways of cleaning from dirt, dust and garbage. The first way implies, literally blowing out the keyboard of garbage and the use of brushes for removing dust and dirt.

The second option is more complex - it includes disassembling the device.

  • On the new models, the upper part of the case, where the panel is located, is attached to the bottom with the help of special latches and bolts. This instruction is especially useful if the buttons do not work on the ASUS laptop, because The latch system is put on all their devices;
  • But in order to gain access to these latches, you need to unscrew the bolts from the bottom of the housing of the cross screwdriver;
  • After the bolts are unscrewed, a flat screwdriver must be carefully released the latches throughout the entire body, but it should be done very carefully;
  • After the latches are open, it is necessary to slowly raise the upper part of the case, until the cable loops and keyboards are visible (it is very narrow, it is very wide for the keyboard);
  • Disconnecting the loops, the user will access the inside of the keyboard with silicone linings. And here you can use a brush or a thin wet napkin to remove dust and garbage.

Returning tracks on the keyboard

If it really is in damage to the tracks, it is recommended to contact the service center, because Nonprofessional will hardly solve the problem independently.

  • It takes the same way as when cleaning from dirt and dust, disassemble the laptop. The fee is a thin polyethylene sheet with a key of the buttons deposited by a special composition;
  • As a rule, the fee is either damaged or there are traces of liquid. If it is just traces of a liquid, then it is clear enough to wipe the place with an alcohol napkin, and then wipe dry with a dry napkin;
  • If the board is damaged, then you need to know damaged places. It is necessary to call the tester all the tracks and find problematic;
  • After the defective tracks are found, you need to take a conductive glue, and re-apply the layer of this glue. It is necessary to do everything very carefully, and otherwise you can simply spoil the board (picture 8).

You can check the work of the tracks with their "transk" with the help of the tester. In fact, the time and strength of the tracks to repair the tracks is incommensurable with the cost of fixing the keyboard in the service center, because Experts will make it faster and cheaper.

Reinstall the driver with a non-working keyboard

Knowing that the problem is in the driver and knowing that the keyboard does not work, you must reinstall the driver using the virtual keyboard.

To open it on Windows 10 you need:

  • Open the control panel through the Start menu;
  • Open center special features;
  • Select the section "Turn on the on-screen keyboard.

You can also use the physical keyboard (of course, if it is in stock), you just need to connect it to a laptop via USB, it will automatically install drivers on a laptop. This is a good temporal replacement of a broken keyboard if the repair is postponed indefinitely.

By right-clicking on the Start menu, you need to open the device manager, find the operating keyboard driver there and delete it.

Next, go to the Internet and download a new driver from the laptop manufacturer, pre-clarifying your model to download software for the desired device.

If the cause of the keyboard button failure, I used the same on-screen keyboard and the mouse, it is required to enable the computer check with an antivirus, to find the virus if possible, delete it, and then also reinstall the keyboard driver.

You can install the so-called drivers. The most popular are Driverpack Solution or Slim Drivers.

This is a whole database that contains drivers to various laptop models.

Advantages of driver-packs:

  • drivers almost all models of laptops;
  • constant updating of the base;
  • Simple installation in automatic mode.

It is very convenient when you want to use the keyboard, and it does not work and you need to quickly fix it.

Cons Bases with drivers:

  • The "left" software is downloaded - you need to go to the expert mode and turn off the injection and installation of useless programs;
  • Bases are subject to infection with viruses - if you have a working antivirus, then everything is OK;
  • The possibility of incompatibility of drivers with devices - this happens rarely.

If spilled liquid on a laptop

Due to the spilled fluid, the buttons may not work even on the laptop touchpad. If the whole surface is strongly filled, you need to do the following:

  • As fast as possible, just as possible, turn off the computer;
  • Open the top cover. Disconnect the battery (it is connected to the motherboard with a special loop or several wiring);
  • After the laptop is de-energized, it is required to clean all layers of the keyboard: silicone lining, aluminum substrate, circuit board;
  • After that, it is possible for the confidence to "ring" contacts the microcircuit and collect all over again.

If the buttons on the laptop still do not work, it is better to check the loop that goes from the keyboard to the motherboard.

Do not work buttons on a laptop - other problems

If the reason that the buttons on the laptop keyboard stopped working, it is, for example, a mechanical impact (a laptop drop), it is better to immediately contact the service center, because you can not always know the problem yourself.

FN button does not work on a laptop

Fn - It may not work as the function key for the following reasons:

  • The lack of the desired software when installing or reinstalling the keyboard drivers (solved by reinstalling the driver);
  • Some of the pre-installed programs relating to the manufacturer and the system keys that the system keys have been removed from the startup (it all depends on the manufacturer). HP Unified Extensible Firmware Interface - If this button does not work on the HP and ATKACPI Driver and Hotkey-Related Utilities - if on Asus;
  • BIOS reset. Changing the behavior of this button in BIOS is not on all laptops. This is all in the "System Configuration" section, in the Action Keys Mode item must be disabled.

If the power button does not work on a laptop

Causes of refusal:

  • Keys wear (erased silicone base buttons, located under plastic);
  • Liquid track path on the board;
  • The key was damaged mechanically.

Solutions in this case will either replace the button or opening the laptop and repairing fixtures (it is better to immediately give to the service)

Do not work buttons on the laptop keyboard - follow the rules!

If the buttons do not work on the laptop, this is alarming bell for the device owner. This suggests that he prefers to ignore some safety rules, it does not follow the updates of the device, does not often use antivirus. Thus, he creates more problems for himself.

Keyboard is an important part of any computer or laptop. Without it, it is almost completely limited to the functionality of not only any programs, but also in the whole operating system.

Behind her, just like the other components of the laptop and PC follow:

  • Simple diagnostics - Checking the performance of some keys will simplify the task. You need to pay attention to the indicators if they are, try to use the function keys;
  • It is required to maintain cleanliness in the room in which the laptop is located, because In contrast to a stationary computer, its body is less protected and the laptop itself practically does not have separate components, so the injection of liquid or dust on the keyboard can damage not only it;
  • It is required to arrange preventive tests of OS (operating system) antivirus. This will allow you to identify viruses at an early stage, until the entire computer has not suffered.

It is clear that neglecting the rules of operation and prophylactic checks of the software update lead to the fact that in the end, some part of the laptop can completely fail and its repair will be very expensive.

Unfortunately, there are no things in the world who would serve forever. Over time, the performance of any items we use in everyday life, especially such complex and damage-sensitive, as a laptop or computer keyboard are worse. It is most often refused to work individual buttons, and it makes it seriously difficult to use the keyboard.

Liquid - the main enemy buttons

Up to 90% of all the breakdowns of the laptop or computer keyboard are associated with hitting the liquid buttons. Most often, we are faced with a bad habit of using a computer, at the same time getting from a cup of coffee or hot tea. One incorrect movement - and the cup overturns, and the drink is generously cutting down the keys.

In this case, the most important thing is to quickly de-energize the device, so that as few elements of its tender electronic structure has experienced the simultaneous effect of water and electric current. So, if you spilled liquid to the keys:

- Quickly turn off the device: pull the power cord, pull the battery from the laptop;

- turn the laptop or keyboard with the key to the key to the liquid that falls inside, without interference has flowed;

- Wipe the housing from above with a dry towel.

Include a laptop to complete fluid drying is not recommended, so you will have to suffer for a couple of days. However, you can always open the case and dry moisture remnants manually.

After drying a drink on the contact sites of the keys, traces of a liquid may remain, impede triggering. Therefore, the keyboard in any case must be opened and cleaned. Only after that you can enable the device and evaluate damage.

Dirt and crumb

As you know, inside the keyboard of any user stored a stock of crumbs on a black day. The trouble is that the remains of food, as well as dust and other trash, inevitably falling inside the keyboard in the slots between the buttons, are able to seriously deteriorate its performance.

Some buttons can fully stop hardware, others can work "once". Exit the situation only one: you need to clean the keyboard. There are two possibilities here:

- cleaning the keyboard without autopsy with a powerful vacuum cleaner with a soft-scaling-brush;

- Opening the case and thorough cleaning of all internal elements. The first method is available to almost everyone, but it allows you to get rid of crumbs and garbage, freely lying inside the keyboard. If the dirt thoroughly nalled on the keyboard elements, it will not be possible to remove it with a vacuum cleaner. In this case, only complete cleaning with the opening of the housing will help, including:

- dismantling of all keys;

- spreading plastic layers with current-paced tracks;

- flushing and dried by dismantled elements;

- check track multimeter (call);

- restorative propagation of tracks, if there is a need for this;

- gluing and assembling of all items.

If you are not sure that you bring the laptop after cleaning - it is better to refer to this regard to the service center.

Damage to the keyboard loop

In the laptop, the keyboard connects with the motherboard using a plume - a flat cord with the wires pressed in plastic. Due to concussion or for other reasons, thin wiring can break, disturbing contact. Squirt places, contact connectors and other elements can fail.

If the train is damaged, most likely, it will be necessary to replace it or repair, and therefore, it is better to contact the service center with this malfunction.

Software reasons

Sometimes the keyboard refuses for reasons that does not have a physical basis: due to damage to the drivers, the effects of the virus, or the settings error.

- Check if the keyboard connector connects it with a stationary computer from the jack.

- If only the buttons with numbers do not work, check if you accidentally press Num Lock.

- Update keyboard drivers. - Check the system with antivirus, delete damaged and infected files.

- To be able to make these actions when not working keypad, use the ability to connect a virtual keyboard by calling it from the toolbar.

Sometimes users encounter such a problem that they do not work part of the keyboard on the laptop. In principle, it happens that the entire keyboard does not work immediately, but then, most likely, it just needs to be replaced. But if only part of the buttons stops functioning, everything is more complicated.

We will consider everything that can be done in this case independently, without the involvement of specialists.

All the actions presented further are important to perform in the order in which we will talk about them.

Simple ways to solve the problem

Not always to restore the performance of a part of the keyboard, you need to do something complicated. Often the problem is solved quite simple. Therefore, from the beginning, do this:

1. Try to press the Fn and Num Lock keys. It is possible that pressing one of them blocked some buttons on the keyboard.

2. Hold fn and press Num Lock, then release both buttons. In some cases, such a simple way allows you to start a full-fledged keyboard operation.

3. Take a brush and pass it on all buttons. It is possible that some dust accumulated under one of the buttons. If possible, take the vacuum cleaner. On the Internet you can find special vacuum cleaners for the keyboard of a small size.

4. Restart the computer. In some cases, the system may have some minor bug that does not allow specific buttons.

In most cases, the problem will be insignificant, and it can be corrected using one of these actions. If nothing happens, go to the next step.

Fix the program failure

It is possible that the problem is in the wrong operation of some programs or services. To check this option and correct the problem, you must do the following:

1. Boot from under the secure mode without drivers. To do this, restart the computer and immediately start pressing the F8 button. Among the download options will select "Safe Mode".

Note: Depending on the system configuration, the button to select the download mode may differ. Therefore, try using all the buttons from F1 to F12, if pressing F8 does not help. As a result, such a window should appear as shown in Figure 2.

System loading mode selection options

2. Try to create some kind of document and use all the keyboard buttons. You need to check not only those buttons that previously refused to work, but all the others! If the case is really in the software fail, the set of broken keys can vary at each new start.

So, if all buttons work well, it means that the problem is really in the operating system. The most likely solution to the problem lies in updating drivers. It is best to do this in the standard way:

  • Open the Start menu (Windows), then "Control Panel", find there "Device Manager";

Device Manager in Control Panel

  • Open the keyboard item;
  • Usually there is only one keyboard, click on it with the right mouse button and select the "Update Drivers ..." item (if there are several keyboards, which is very unlikely, do the same with everyone);
  • Select the "Automatic Search ..." item;
  • Wait until the drivers are found on the Internet, their installation will occur in automatic mode.

Driver Update Standard Windows Mode

You can also download and install the Driverpack Solution program. It allows you to scan the entire computer for the presence of the latest drivers available. If the keyboard has incorrect (roughly speaking "broken") or irrelevant drivers, you can easily bring them. The use of this program is as follows:

  • Download the program (here is the link);
  • Install it and run;
  • There will be automatic scanning, after which simply click on the "Update All" button.

Window DriverPack Solution

Scan the system with your antivirus and delete all detected viruses. And also for this you can use special utilities such as Kaspersky Virus Removal Tool or Malwarebytes Anti-Malware Free.

If the update and scanning of the drivers does not help, try to roll back the system until it worked well.

To do this, you need to do this:

  • Open the "Start" menu, then "All Programs", "Standard";
  • After that, go to the "Service" section and click on the "Restoration System" item;

Item "Restore System" in the "Start" menu

  • In the window that opens, click "Next";
  • Further select the desired recovery point, and they are sorted here by date and time (you need to choose the one that most accurately matches the time when everything was fine);

Choosing a recovery point for system rollback

  • Click "Next" and then "Finish".

In principle, reinstall the drivers and roll back the system can also be in cases where the keyboard is also incorrect in safe mode. But in this case, the probability that it will help, very small. Most likely, the problem is already mechanical, and not software and solve it needs to be physically interfered with the computer.

Fix physical failure

In this case, you will have to disassemble the keyboard and stages to look, which could be out of order. To do this, follow these steps (it is very important to adhere to just such a order in which all actions will be further listed):

1. Turn off the laptop and remove the battery from it.

2. Take a flat screwdriver and carefully push all the latches of the plate on which the keyboard holds. If you do not see any laptops on your laptop, you should take the instructions and read that it is written about the keyboard device and how it is extracted. In any case, some fastening mechanisms should be present.

The process of opening the keyboard plate latches

The keyboard plate is attached to the laptop itself using a loop. You will immediately see it.

3. So, if it is clear damage, the loop you need to just take out and replace the new one. To do this, take the old train, go to the nearest electronics store and buy the same.

Clay keyboard

4. If the loop is not damaged, it still needs to be removed. The cable at the same time to take the guides in no case! You can only take on those plastic parts with which it is attached to other parts of the laptop. For clarity, in Figure 10 shows those parts for which you can also be taken and those for which it is impossible to take. True, there are usually several other loops in the keyboards.

Plume

5. In the same place, under the keyboard plate you can find a microcontroller. It is necessary dry and try to pull dust With the help of a vacuum cleaner.

Explain how to find this most microcontroller is quite difficult. If you just say, this is exactly the device to which the loop is mounted. Just in case, when removing the keyboard, pass through all the controllers that you will see. Alone without any special knowledge nothing will do anything else. Again, if you will see explicit damage on the microcontroller, it is better to replace it.

6. If everything is fine with the loop, you have to disconnect the keys and clean them. Usually, the button can be removed in the standard way - to pose the same flat screwdriver. Start with problem buttons. If you see damage under them, replace the items that the button is attached to the laptop.

And if all is well, remove all the buttons. Next should be pulled out all the dust and wipe the entire visible surface with an alcohol with alcohol.

The process of seizure the buttons from the keyboard

7. Try to use the keyboard again.

If the problem has not disappeared, remove all the buttons and remove the aluminum plate that is under them. Usually, she also has special attachments that are removed quite easily. But under it is hidden plastic board with drawn tracks.

Inspect it for obvious damage - if any, there are two options: draw new tracks or buy a new board. In any case, walk along the platform with a vacuum cleaner.

To check the integrity of the tracks, use the tester.

Checking the integrity of the tracks on the keyboard board tester

To draw tracks, use the set for repairing the heating of the rear windows of the car (and is called).

If nothing helps, it is best to pass a computer to repair.

Why the keyboard does not work on the laptop: 15 methods of repairing the laptop notes, if it stopped working

reasons why keyboard laptop does not workWrouders of laptops are sooner or later asked why the keyboard does not work on Lenovo, Acer, HP, Asus, Samsung, Sony Vaio or any other. The brand does not matter - the problem may occur on each device. Causes are lurking both in hardware failures and in software errors. Part of the user a user can eliminate independently.

We offer 15 options for troubleshooting a keyboard on a laptop that can help to do without big financial investments, as well as tell about the options for a temporary solution to the problem through the connection of additional equipment. The type of operating system does not matter, it can be any version of Windows.

Starting should always be with the simplest. Checking the power and integrity of the wires must begin any diagnostics of a faulty device. In addition, non-working keyboard keys can be the result of a disconnection of a block with numbers, which is controlled by the NUM LOCK button. The wakewicked crumbs may interfere with connecting contacts while pressing the keys. A fully disconnected keyboard can successfully return to operation after a banal reboot of the computer. Only by eliminating all the simplest reasons, it makes sense to be taken for deep diagnosis.

Hardware Causes Keyboard breakage

It is important to remember that it was preceded by a trip. If there was a drink, the breakdown will be in the brave of contacts, chips, or a loop, which goes to the motherboard.

Failures in the work can manifest itself in the wrong response to the command: when you click on one letter, the user on the screen sees a whole set of characters. Only some modern models are protected from spilled fluid, but they can suffer from sugar dissolved in the drink.

The first thing to be done after the liquid has hit the laptop - disable the power supply device. After that, you can proceed to removing the liquid and wiping the contacts with alcohol. Those who do this for the first time will help youtube videos in which experienced users show how to properly remove the keys from the laptop keyboard or remove it from the case to rinse. It is important not to mix with drying, otherwise it is not on time the keyboard is burning due to the moisture hidden from the eye.

Sometimes the reason why the keyboard on the laptop ceased to work, the contact of the loop becomes. Despite the fact that the factory terminals have hard locks, there is a marriage percentage, which includes unreliable fixing of the peripherals on the motherboard. In this case, it will be enough to connect the contacts denser.

If the simplest manipulations did not help, attention should be paid to the chip: whether contacts did not compound. After that, you need to check the status of the loop and find out whether the residents are not deformed, there is no hard inflection. With all the ambiguities should be sent to the service center, where professionals will establish the true cause of the breakdown and offer its elimination options.

Software Causes of Keyboard Output

Hardware problems are rarely found if the reason is not in the spilled drink. Because for the contact of the loop contact, we need strong and long-lasting vibrations, and for the inflection - pinch it with a lid, which is unlikely if the user never disassembled his laptop computer. Therefore, it is important to exclude all program errors that are increasing much more. Thanks to the embedded Windows diagnostics, you can cope with a number of problems yourself. Find an electronic assistant is easy: "Start" , Menu "Control Panel" section "Troubleshooting" . And for Windows 10: "Start" , then "Options" , Further "Update and Security" section "Troubleshooting" .

Method # 7: If the keyboard does not work after logging into Windows account

This is a particular case in which the keyboard does not work after logging in to the Windows account. When entering the Microsoft account, some parameters and data are saved in oneDrive. Sometimes because of this synchronization, the keyboard stops working.

To disable synchronization and delete this data from ONEDRIVE, you need:

  • Disable the parameter synchronization on all devices that are connected to your account. That is, on all PCs, laptops, phones and tablets.
  • Delete the parameters that were synchronized from oneDrive.

How to disable synchronization in Windows 10:

  1. Open application "Options" .
  2. Select "Accounts" , Further "Parameter Synchronization" .
  3. Set switch "Parameter Synchronization" in the Regulation "Off" .

Method # 8: Try running the CTFMON.exe process manually

Not all users work only in one operating system. If you also have several OS, or you practice downloading from Live CD, a situation is possible when the keyboard does not work on the laptop. How to enable, let's tell in detail. It is important to determine whether the process controlling the user input parameters called ctfmon.exe is launched.

Search it is needed in "Task Manager" tab "Details" . If there are no ctfmon.exe in the processes list, you will have to run it manually. To do this, in the upper left corner of the window "Task Manager" Press "File" , then "Run a new task" . In addition to the window that opens, enter the name of the process in the field. "Ctfmon.exe" . It remains only to click "OK" To estimate the result.

Find the process

If the keyboard work has improved, the process must be added to the autoload list so as not to run it every time manually.

To do this, go to "Registry Editor" which is easy to find through the menu "Start" By writing in the search bar "REGEDIT" . Now you need to get into the folder "HKEY_LOCAL_MACHINE" , of it - in "SOFTWARE" where to find "Microsoft" , to open "Windows" and in it - "CurrentVersion" where is the desired "RUN" .

Open the registry branch

Opening "Edit" , you need to create a new parameter whose type will be - "String" , and name - "CTFMON" with meaning "% Systemroot% System32ctFmon.exe" . After that, it is necessary to initiate the restart of the laptop.

Edit the Registry parameter

Method # 9: Check the laptop for viruses

On each computer: stationary or portable should stand antivirus. The network access is always the risk to infect the device with malicious programs, which not only to work applications affect, but also interfere with the normal functioning of iron, which is why the keyboard does not work on the laptop. Reasons will help to eliminate high-quality antivirus. Payable programs with updated bases are the most reliable.

And, before removing the next tick, to put the previous one.

Method # 12: If the keys do not partially work, clean the keyboard

When a part of the buttons on the laptop keypad does not work, you must make sure that the contacts do not interfere with anything, reading the device from pollution.

First, turn off the laptop, disconnecting it from the network.

  • Photographed before disassembling the position of the keys, it will be possible to avoid confusion while setting the buttons to place after cleaning.
  • Each key with reinforcing pull up, pushing it with something solid and thin, such as a knife.
  • After removing all the buttons, remove the dust with the help of a vacuum cleaner.
  • The dismantled letters can be washed in warm soapy water, and then completely dry.
  • The field on which the keys is located, you need to wipe with a wet cloth or cotton walle.
  • After all the contaminants are deleted, set the keys to the place, using the pre-made photo.

Method # 13: Update Windows

It's easy to do in the section "Updates and Security" . There, in the update log, you need to find the installed package to be deleted, and after - restart the laptop.

Method # 14: System Restore

To this item should be resorted if several programs have been established, after which the buttons on the laptop keyboard stopped working, as well as when all previous tips did not give results.

Following the prompts of the dialog box, specify the date of the control point, which is considered successful. In other words, the day when all the peripherals of the laptop worked without failures.

Method # 15: Check the keyboard loop

The keyboard stopped working on the laptop. What if all the above options did not help - find out if there is a signal from the keyboard to the motherboard. For this we will analyze the laptop. If you are not used to working with a screwdriver or afraid that after removing the lid, the entire laptop will stop working - it is better not to start and entrust the work of a service or more experienced comrade.

We decided to disassemble yourself - to use the video recordings with YouTube, where the cover is removed from the exact same model as yours. Photographing each step will not be an error, because when assembling it may be that in front of you are cogs of different lengths: one is black, others are silver, and which were scratched, you no longer remember.

If to get to the keyboard, you need to remove the hard disk and the cooler - do not be afraid, take pictures of them in a fixed form and boldly unscrew. All items remove slowly, without sharp movements, because thin tires or wires can be hiding under them connecting them with food or motherboard. When access to a wide keyboard loop is obtained, check the quality of its fixation on both sides, look carefully, whether the veins are not interrupted along the entire length of the loop. It will not be superfluous to check the contacts at the location of the fixation - the flight or oxidation must be deleted and connect the keyboard back.

Final advice

If half the keyboard does not work on the laptop, or the device has not been fully refused, you should not plan the purchase of a new PC. Even the lack of the result after conducting self-diagnosis on our advice is not a reason to say goodbye to technology. In the service center can replace the burned outflow of the motherboard, which is responsible for the operation of the keyboard or replace the input device new. Tell the master everything that happened to the breakdown and how you were looking for a reason to speed up the diagnosis.

Will this article help you?

Yes Not

Sometimes users encounter such a problem that they do not work part of the keyboard on the laptop. In principle, it happens that the entire keyboard does not work immediately, but then, most likely, it just needs to be replaced. But if only part of the buttons stops functioning, everything is more complicated.

We will consider everything that can be done in this case independently, without the involvement of specialists.

All the actions presented further are important to perform in the order in which we will talk about them.

Part of the keyboard on the laptop does not work

Simple ways to solve the problem

Not always to restore the performance of a part of the keyboard, you need to do something complicated. Often the problem is solved quite simple. Therefore, from the beginning, do this:

1. Try to press the Fn and Num Lock keys. It is possible that pressing one of them blocked some buttons on the keyboard.

2. Hold fn and press Num Lock, then release both buttons. In some cases, such a simple way allows you to start a full-fledged keyboard operation.

3. Take a brush and pass it on all buttons. It is possible that some dust accumulated under one of the buttons. If possible, take the vacuum cleaner. On the Internet you can find special vacuum cleaners for the keyboard of a small size.

4. Restart the computer. In some cases, the system may have some minor bug that does not allow specific buttons.

In most cases, the problem will be insignificant, and it can be corrected using one of these actions. If nothing happens, go to the next step.

Fix the program failure

It is possible that the problem is in the wrong operation of some programs or services. To check this option and correct the problem, you must do the following:

1. Boot from under the secure mode without drivers. To do this, restart the computer and immediately start pressing the F8 button. Among the download options will select "Safe Mode".

Note: Depending on the system configuration, the button to select the download mode may differ. Therefore, try using all the buttons from F1 to F12, if pressing F8 does not help. As a result, such a window should appear as shown in Figure 2.

2. Try to create some kind of document and use all the keyboard buttons. You need to check not only those buttons that previously refused to work, but all the others! If the case is really in the software fail, the set of broken keys can vary at each new start.

So, if all buttons work well, it means that the problem is really in the operating system. The most likely solution to the problem lies in updating drivers. It is best to do this in the standard way:

  • Open the Start menu (Windows), then "Control Panel", find there "Device Manager";

Part of the keyboard on the laptop does not work

Device Manager in Control Panel

  • Open the keyboard item;
  • Usually there is only one keyboard, click on it with the right mouse button and select the "Update Drivers ..." item (if there are several keyboards, which is very unlikely, do the same with everyone);
  • Select the "Automatic Search ..." item;
  • Wait until the drivers are found on the Internet, their installation will occur in automatic mode.

Part of the keyboard on the laptop does not work

Driver Update Standard Windows Mode

You can also download and install the Driverpack Solution program. It allows you to scan the entire computer for the presence of the latest drivers available. If the keyboard has incorrect (roughly speaking "broken") or irrelevant drivers, you can easily bring them. The use of this program is as follows:

  • Download the program (here is the link);
  • Install it and run;
  • There will be automatic scanning, after which simply click on the "Update All" button.

Window DriverPack Solution

Scan the system with your antivirus and delete all detected viruses. And also for this you can use special utilities such as Kaspersky Virus Removal Tool or Malwarebytes Anti-Malware Free.

If the update and scanning of the drivers does not help, try to roll back the system until it worked well.

To do this, you need to do this:

  • Open the "Start" menu, then "All Programs", "Standard";
  • After that, go to the "Service" section and click on the "Restoration System" item;

Part of the keyboard on the laptop does not work

Item "Restore System" in the "Start" menu

  • In the window that opens, click "Next";
  • Further select the desired recovery point, and they are sorted here by date and time (you need to choose the one that most accurately matches the time when everything was fine);

Choosing a recovery point for system rollback

  • Click "Next" and then "Finish".

In principle, reinstall the drivers and roll back the system can also be in cases where the keyboard is also incorrect in safe mode. But in this case, the probability that it will help, very small. Most likely, the problem is already mechanical, and not software and solve it needs to be physically interfered with the computer.

Fix physical failure

In this case, you will have to disassemble the keyboard and stages to look, which could be out of order. To do this, follow these steps (it is very important to adhere to just such a order in which all actions will be further listed):

1. Turn off the laptop and remove the battery from it.

2. Take a flat screwdriver and carefully push all the latches of the plate on which the keyboard holds. If you do not see any laptops on your laptop, you should take the instructions and read that it is written about the keyboard device and how it is extracted. In any case, some fastening mechanisms should be present.

The process of opening the keyboard plate latches

The keyboard plate is attached to the laptop itself using a loop. You will immediately see it.

3. So, if it is clear damage, the loop you need to just take out and replace the new one. To do this, take the old train, go to the nearest electronics store and buy the same.

4. If the loop is not damaged, it still needs to be removed. The cable at the same time to take the guides in no case! You can only take on those plastic parts with which it is attached to other parts of the laptop. For clarity, in Figure 10 shows those parts for which you can also be taken and those for which it is impossible to take. True, there are usually several other loops in the keyboards.

5. In the same place, under the keyboard plate you can find a microcontroller. It is necessary dry and try to pull dust With the help of a vacuum cleaner.

Explain how to find this most microcontroller is quite difficult. If you just say, this is exactly the device to which the loop is mounted. Just in case, when removing the keyboard, pass through all the controllers that you will see. Alone without any special knowledge nothing will do anything else. Again, if you will see explicit damage on the microcontroller, it is better to replace it.

6. If everything is fine with the loop, you have to disconnect the keys and clean them. Usually, the button can be removed in the standard way - to pose the same flat screwdriver. Start with problem buttons. If you see damage under them, replace the items that the button is attached to the laptop.

And if all is well, remove all the buttons. Next should be pulled out all the dust and wipe the entire visible surface with an alcohol with alcohol.

7. Try to use the keyboard again.

If the problem has not disappeared, remove all the buttons and remove the aluminum plate that is under them. Usually, she also has special attachments that are removed quite easily. But under it is hidden plastic board with drawn tracks.

Inspect it for obvious damage - if any, there are two options: draw new tracks or buy a new board. In any case, walk along the platform with a vacuum cleaner.

To check the integrity of the tracks, use the tester.

What to do if some keys do not work on the keyboard

What to do if some buttons do not work on the keyboard?

One of the most common problems with which any computer user faced is a partial or complete keyboard failure, in which no pair of buttons do not work or the entire laptop.

From our article you will learn what to do if Some buttons do not work on the laptop keyboard And for what reasons could fail.

Keypad breakdown options

The broken keyboard is a fairly blurry concept. The first thing you need to do when the keys failure is to determine the type of breakage:

  1. broken and do not respond to user actions all keys;
  2. Fully does not function multiple keys (system or functional);
  3. Multiple keys stick out, work only with strong presses;
  4. broken keys of the right block (with numbers);
  5. All buttons do not respond to user actions, the lights disappeared.

Categories of category 2-4 are easily eliminated and do not require access to the service: In this case, even an unprepared person will be able to reanimate the device without any problems.

For categories 1 and 5, a complete analysis of the keyboard is required, which involves the presence of special skills and time.

If you are not sure of your own, it is better to contact a specialist: this will allow you to quickly and efficiently eliminate the problem and do not worsen the situation.

Causes of keyboard failure

Before talking about the main methods of fixing the keys, consider the most common situations, Why some buttons on the keyboard do not work. Depending on the cause of the problem, the solution is solutions can vary greatly.

Do not work some keys

1. Refused the keyboard right-hand keys - in this case, you should not rush to the master or start disassembling the laptop.

A frequent cause of the failure is random shutdown of the Num Lock function, which leads to blocking this part of the keyboard.

To find out if Num Lock is enabled, you must check the indicator on (it has the designation "1"): If the light is on - the function is active if the backlight is missing - you must repeat the corresponding key.

Do not work some laptop keys

2. One or more keys stick.

  • The most common cause of this error is to pollute the keys. The problem is easily eliminated in the process of cleaning the laptop. A distinctive feature of contamination of the device is the need for stronger pressing for a specific key.
  • The problem may be associated with the wear of the device: any key is designed for a certain load (usually about 50 thousand clicks). Over time and with active use, wearing thin wires and closing tracks, acidification of conductive contacts occurs. Under this reason, the breakdown first refuse the most used keys.

3. A number of keys do not fully function. If the keyboard is cleaned, and the buttons continue not to react to pressing, then the cause of the failure is more serious: most likely broken tracks.

All keyboard does not work

1. Software crash. The most frequent program reasons for the complete failure of the functionality of the buttons are:

  • failure of software;
  • Driver breakdown;
  • Incorrect BIOS settings;
  • PC transition to safe operation mode;
  • incorrect operation of the operating system;
  • PC infection or laptop viruses, etc.

To repair Lappleop, it is necessary to quickly eliminate the software failure.

2. Mechanical damage to the keyboard, under which the disruption of the integrity of the device is understood as a result of external influence, including falling, impact, water entering:

  • Clean the cable or loop cable inside the keyboard connecting all the internal elements of the device;
  • violation of the integrity of ports;
  • the destruction of internal contacts;
  • mechanical damage to the loop;
  • Battery breakdown (Battery replacement is required);
  • The oxidation of the contacts of the laptop loop and, as a result, the combustion of the chip (most often occurs as a result of water entering).

In the event that independent diagnostics does not allow you to identify the cause of the keyboard breakdown, it is recommended to contact a specialist.

Wrong repair or non-professional intervention in the inner device of the laptop can lead to its full failure, which is especially problematic for laptops: the keyboard replacement requires the selection of the optimal model for a particular device.

Ways to eliminate keyboard breakdown

The failure of several or all keys is not the reason to throw out the old keyboard and go to search new. In most cases, the previous device can be reanimated, and without contacting the service.

Next we will tell what to do if some keys on the keyboard do not work And we will tell about the main methods of repair depending on the cause of the mechanism failure.

The keyboard was filled with water

According to statistics, each 100 cup, drinking at the computer turns out to be spilled on the keyboard. If you accidentally poured your laptop tea, coffee or ordinary water, you should not worry - immediately go to the elimination of the problem:

  1. To avoid contacting, disconnect the keyboard from the power supply: for a laptop - disconnect the cable for a laptop - remove the laptop;
  2. If the keys hit the keys with impurities (sweet tea, soda, juice, etc.), it is necessary to gently rinse the keys under water using the tool for dishes;
  3. Leave the device to complete drying (use hairdryer and other fixtures are not recommended);
  4. Connect the device to the computer and check the key reaction;
  5. If the resuscitation of your device failed, you will need a complete keyboard pacing with the subsequent rubbing of all Ethyl alcohol elements: at this stage it is important to inspect the tracks and, if they are suspected damage, to be treated with special conductive glue;
  6. In the event that the above listed manipulations did not help, repair the device is no longer possible: the only option is to purchase a new one.

The keyboard was filled with water

In the keyboard accumulated garbage

With a strong contamination, the process of resuscitation of the keyboard is carried out according to the following algorithm:

1. Inspect the keyboard for identifying the most insane sites;

2. Disconnect the laptop or computer from the power supply;

3. Remove the keys around which trash accumulated:

  • Press the key from above;
  • Pattail it from below with a thin tool: needle, pin, screwdriver (top latch);
  • Continue disabling the rest of the key latches - all of them 5 or 6 (depending on the model);
  • Upon completion of the procedure, lift the button and gently disconnect the loop.

In the keyboard accumulated garbage

Important: In the process of disconnecting the loop, keep the wire only for the plastic part - this will avoid damage to the contacts and the breakage of the loop.

4. Upon completion of dismantling of all contaminated keys, go to the cleansing of your gadget. For cleaning, ethyl alcohol, alcohol napkins or specialized cleaners are required. The disassembled device is cleaned in manual with a small bruster and a sponge with liquid. This method requires increased accuracy and caution: it is important not to damage the chip.

5. After cleaning, you must collect the keyboard:

  • Lower each key to the spring element in the central part of the corresponding site;
  • Press the button to the sound of clicking;
  • Carefully contact the loop: in the case of attaching it in an inverted form, the keyboard will not work.

Alternative ways of cleaning that do not require keyboard pars are:

  • Cleaning the buttons using compressed air: For this, we will need a special canister (you can buy in the store electrical engineering) or standard vacuum cleaner. In the "Fold" mode, clean the device from dust, crumbs and the rest of the garbage. You can also use a special keyboard vacuum cleaner - sold in a number of computer stores.

Special vacuum cleaner for keyboard

  • Cleaning keys by a special sticky composition: This will require you to buy a special "velcro" for the keyboard. The acquired velcro should be put on the disassembled keyboard and slightly press - the mass is spread over the surface. After a few minutes, begin to catch the "Velcro": all the garbage and dust glued to it and can be neatly eliminated without damaging the buttons.
  • PC owners can use a simpler and quick way to clean the keyboard from the garbage: flip the device and knock on its back side slightly. So you can "knock out" from under the buttons a significant part of crumbs and dust.

Recommend to reading: Laptop diagnostic program

Plurif damage

If, as a result of the keyboard parsing, it was found that the reason why Some buttons on the laptop keyboard do not work, is a train, you need:

  • Clean the flight and rust with wiring with ethyl alcohol;
  • When damaged wires or sagging, they need to be replaced.

Before the complete breakdown of the loop, partial failures are observed in the keyboard operation: flashing multiple keys, decreased brightness or flashing the keyboard backlight, etc.

Repair the train yourself, especially on the laptop, is not recommended: To penetrate the inside of the keyboard, you need to remove the rear lid of the device, so in case of careless actions, you can damage the motherboard. This will lead to its full breakdown.

Hitting the BIOS settings

If only the function keys refused (F1-F12), then you will need to correctly configure the BIOS:

  1. Go to the BIOS settings;
  2. Change the function keys mode to "HotKey Mode";
  3. If the action has not led to success, we recommend reinstalling the driver.

Software failure

If you have Do not work some keys on the keyboard Due to the software failure, it is necessary to eliminate its reasons for fixing the device:

  • With incorrect driver operation:
  1. Download on the Internet the current version;
  2. Install the program on a PC or laptop;
  3. Restart the laptop or computer.
  • Computer infection with viruses: cleaning your device with a licensed antivirus program;
  • The incorrect operation of the operating system: Reinstalling OS.

What if the keyboard is needed urgently

If you have Some keyboard buttons do not work And there is no repair or cleaning time, you can use the following temporary measures:

  • reassign the buttons that have stopped functioning to operating (through the MapKeyboard or Other Program);
  • Use the on-screen keyboard ("Start" menu, section "Special Features");
  • Connect the external keyboard to the computer (via a USB connector).

Ask a question expert

The reasons for which the buttons on the laptop do not work can be a lot. All faults belong to either a hardware or software. We will analyze the most common causes of keyboard failure. We will analyze how to behave in a situation where the laptop spill a liquid.

Do not work buttons on a laptop - we are looking for reasons for the cause

The solution of the problem always begins with the search for the causes of its occurrence. The reason may be a hardware type, when the keyboard was damaged physically and software, when the buttons cause is an error somewhere in a virtual environment.

It is necessary to make a small diagnosis to approximately understand what happened. To do this, you need to check which keys do not work.

  • All keys do not respond;
  • Sticks part of the keys;
  • Only some buttons do not work;
  • Does not correspond to the digit block on the right;
  • Everything is completely not working, including indicators.

Such an easy-to-first diagnostics will help determine the further action on the fixing of the keyboard.

Does not respond to the commands right block numbers

Here you can immediately write a solution. Usually above the number "7" is the so-called function key "Numlock".

Do not work buttons on a laptop

Her pressing blocks all the numbers in the right block. The fact that it is active is evidenced by a special indicator, but since there are no indicators on new models, you can only check it out, and then try pressing the numbers from the block.

Sharp keyboard keys

Under the shaking keys in this case, there is a long response or no reaction after one press as a result of the accumulation of garbage under the keyboard.

Damage to tracks

If, after scratching the keyboard panel from the garbage, some buttons on the laptop do not work anyway - it means there is a serious problem, namely, damage to the board tracks.

Software reasons

As for the program part, then the keyboard failure may be due to the fact that the driver has been removed for any other reasons. The second most frequent cause is a virus on a computer that can damage the software components of the keyboard.

Contact Oxification for keyboard loop

Everything is connected to the main or motherboard with a wide loop. Throughout the loop, there may be contacts, and they can oxidize, with time or as a result of the fact that the keyboard was shed liquid.

Refusal of the keyboard board

The keyboard board consists of several microcircuits, which are interconnected. Spilled liquid, mechanical impact or adverse storage conditions of a laptop can lead to oxidation of contacts or in general to the full failure of the board.

Laptop buttons do not work - troubleshooting

Immediately after clarifying the circumstances, the breakdown can start repairing the keyboard. If you are not a confident user, and you are not used to working with computer components - do not experiment! Contact the service center. Popular repair can cause even more problems.

Keyboard repair on software or hardware level does not require special skills and knowledge. Unless of course it is not damage to chips or the entire board.

Cleaning the keyboard from garbage

Sooner or later, the keyboard begins to pollute. Depending on how she enjoys the laptop owner: how often he eats behind him, as often he is removed in the room, where there is a laptop. With a high degree of pollution and start problems with the buttons sticking.

In order to clean the space between the buttons and the following will be required:

  • Special brush for cleaning hard-to-reach places - gaps between the laptop housing and keys;
  • Vacuum cleaner, sprayed aircraft or hairdryer;
  • With a strong need, the cross screwdriver of small size and flat of any size, but not too large.

There are two ways of cleaning from dirt, dust and garbage. The first way implies, literally blowing out the keyboard of garbage and the use of brushes for removing dust and dirt.

The second option is more complex - it includes disassembling the device.

  • On the new models, the upper part of the case, where the panel is located, is attached to the bottom with the help of special latches and bolts. This instruction is especially useful if the buttons do not work on the ASUS laptop, because The latch system is put on all their devices;
  • But in order to gain access to these latches, you need to unscrew the bolts from the bottom of the housing of the cross screwdriver;

Notebook

  • After the bolts are unscrewed, a flat screwdriver must be carefully released the latches throughout the entire body, but it should be done very carefully;

Laptop keyboard disassembly

  • After the latches are open, it is necessary to slowly raise the upper part of the case, until the cable loops and keyboards are visible (it is very narrow, it is very wide for the keyboard);

Do not work buttons on the keyboard

  • Disconnecting the loops, the user will access the inside of the keyboard with silicone linings. And here you can use a brush or a thin wet napkin to remove dust and garbage.

Do not work buttons on a laptop

Returning tracks on the keyboard

If it really is in damage to the tracks, it is recommended to contact the service center, because Nonprofessional will hardly solve the problem independently.

  • It takes the same way as when cleaning from dirt and dust, disassemble the laptop. The fee is a thin polyethylene sheet with a key of the buttons deposited by a special composition;

Do not work buttons on a laptop

  • As a rule, the fee is either damaged or there are traces of liquid. If it is just traces of a liquid, then it is clear enough to wipe the place with an alcohol napkin, and then wipe dry with a dry napkin;
  • If the board is damaged, then you need to know damaged places. It is necessary to call the tester all the tracks and find problematic;

Do not work buttons on a laptop

  • After the defective tracks are found, you need to take a conductive glue, and re-apply the layer of this glue. It is necessary to do everything very carefully, and otherwise you can simply spoil the board (picture 8).

You can check the work of the tracks with their "transk" with the help of the tester. In fact, the time and strength of the tracks to repair the tracks is incommensurable with the cost of fixing the keyboard in the service center, because Experts will make it faster and cheaper.

Reinstall the driver with a non-working keyboard

Knowing that the problem is in the driver and knowing that the keyboard does not work, you must reinstall the driver using the virtual keyboard.

To open it on Windows 10 you need:

  • Open the control panel through the Start menu;
  • Open center special features;

Key Milavra Repair

  • Select the section "Turn on the on-screen keyboard.

Do not work buttons on a laptop

You can also use the physical keyboard (of course, if it is in stock), you just need to connect it to a laptop via USB, it will automatically install drivers on a laptop. This is a good temporal replacement of a broken keyboard if the repair is postponed indefinitely.

By right-clicking on the Start menu, you need to open the device manager, find the operating keyboard driver there and delete it.

Screen keyboard

Delete Driver

Next, go to the Internet and download a new driver from the laptop manufacturer, pre-clarifying your model to download software for the desired device.

If the cause of the keyboard button failure, I used the same on-screen keyboard and the mouse, it is required to enable the computer check with an antivirus, to find the virus if possible, delete it, and then also reinstall the keyboard driver.

You can install the so-called drivers. The most popular are Driverpack Solution or Slim Drivers.

Driver Pak Solyushen

This is a whole database that contains drivers to various laptop models.

Advantages of driver-packs:

  • drivers almost all models of laptops;
  • constant updating of the base;
  • Simple installation in automatic mode.

It is very convenient when you want to use the keyboard, and it does not work and you need to quickly fix it.

Cons Bases with drivers:

  • The "left" software is downloaded - you need to go to the expert mode and turn off the injection and installation of useless programs;
  • Bases are subject to infection with viruses - if you have a working antivirus, then everything is OK;
  • The possibility of incompatibility of drivers with devices - this happens rarely.

If spilled liquid on a laptop

Due to the spilled fluid, the buttons may not work even on the laptop touchpad. If the whole surface is strongly filled, you need to do the following:

  • As fast as possible, just as possible, turn off the computer;
  • Open the top cover. Disconnect the battery (it is connected to the motherboard with a special loop or several wiring);

Do not work buttons on a laptop

  • After the laptop is de-energized, it is required to clean all layers of the keyboard: silicone lining, aluminum substrate, circuit board;
  • After that, it is possible for the confidence to "ring" contacts the microcircuit and collect all over again.

If the buttons on the laptop still do not work, it is better to check the loop that goes from the keyboard to the motherboard.

Do not work buttons on a laptop - other problems

If the reason that the buttons on the laptop keyboard stopped working, it is, for example, a mechanical impact (a laptop drop), it is better to immediately contact the service center, because you can not always know the problem yourself.

FN button does not work on a laptop

FN button does not work on a laptop

Fn - It may not work as the function key for the following reasons:

  • The lack of the desired software when installing or reinstalling the keyboard drivers (solved by reinstalling the driver);
  • Some of the pre-installed programs relating to the manufacturer and the system keys that the system keys have been removed from the startup (it all depends on the manufacturer). HP Unified Extensible Firmware Interface - If this button does not work on the HP and ATKACPI Driver and Hotkey-Related Utilities - if on Asus;
  • BIOS reset. Changing the behavior of this button in BIOS is not on all laptops. This is all in the "System Configuration" section, in the Action Keys Mode item must be disabled.

Reset BIOS settings

If the power button does not work on a laptop

Causes of refusal:

  • Keys wear (erased silicone base buttons, located under plastic);
  • Liquid track path on the board;
  • The key was damaged mechanically.

Solutions in this case will either replace the button or opening the laptop and repairing fixtures (it is better to immediately give to the service)

Do not work buttons on the laptop keyboard - follow the rules!

If the buttons do not work on the laptop, this is alarming bell for the device owner. This suggests that he prefers to ignore some safety rules, it does not follow the updates of the device, does not often use antivirus. Thus, he creates more problems for himself.

Keyboard is an important part of any computer or laptop. Without it, it is almost completely limited to the functionality of not only any programs, but also in the whole operating system.

Behind her, just like the other components of the laptop and PC follow:

  • Simple diagnostics - Checking the performance of some keys will simplify the task. You need to pay attention to the indicators if they are, try to use the function keys;
  • It is required to maintain cleanliness in the room in which the laptop is located, because In contrast to a stationary computer, its body is less protected and the laptop itself practically does not have separate components, so the injection of liquid or dust on the keyboard can damage not only it;
  • It is required to arrange preventive tests of OS (operating system) antivirus. This will allow you to identify viruses at an early stage, until the entire computer has not suffered.

It is clear that neglecting the rules of operation and prophylactic checks of the software update lead to the fact that in the end, some part of the laptop can completely fail and its repair will be very expensive.

Reshenie-Problem-S-KlaviaturoyGood times day!

If there is no problem with a conventional keyboard for a PC, it broke, bought a new one, then with laptops not everything is so simple:

  • First, it is enough to find it in some cases;
  • Secondly, it is not easy independently to change (sometimes it is necessary to disassemble all the device);
  • Thirdly, not always the inoperability of some keys is related to the malfunction (and on this, many users are burned down ...)!
  • Fourth, the keyboard of the laptop often "bites" at the price (it is much more expensive).

Actually, in this article I want to give some of the exact reasons, because of which the keys can stop. In addition, it is not always worth running at the new keyboard immediately - you see if you do not work 1-2 keys (which are not so often used), then you can quite do without them?

In general, in this article I will give different options for the causes, solutions, and that in general it can be done if you encountered this problem.

So...

What to do if you do not work some keys

Testing all keys under the other OS

To begin with, I would like to recommend to thoroughly check all the keyboard buttons using one handy utility - Keyboard Test Utility. Just, maybe so that you know only one key, and you still do not work 2-3 (Yes, and the problem can be a programmic character) !

The utility is extremely simple (it does not need installation): After it starts it, you will appear with the keyboard (👇). When you press some key - it will be filled with yellow.

Your task is to shake all the keys!

Of course, to place all the points above "and" - we need to create an emergency LiveCD flash drive (and also record the Keyboard Test Utility utility).

Next, boot from this flash drive, and start checking the keyboard (thanks to this simple test - we will make sure that the inoperability of the keyboard is not related to the errors from the current version of Windows ...).

Whether keys are turned off in BIOS (relevant for Fn, F1 ÷ F12)

If you do not work function keys ( F1 ÷ F12. ), either special. key FN. - It is possible that the problem lies not in the keys themselves, but in the BIOS settings (UEFI).

By the way, I note that by default on many laptops, the function keys are disabled (Instead, excellent functions are performed: add volume, on / off. Wi-Fi, screen brightness adjustment, etc.) .

As a rule, you must enter the BIOS and change the mode of operation functionality. keys (the name of the parameter something like "HotKey Mode", as in the screenshot below).

Trash under the keys (dust, crumbs, hair)

Most often, the cause of a bad triggement of most keys is garbage and dust, which over time accumulate under them.

A characteristic feature in this case: with a weak press, the key does not work, however, when you press with some effort - the key works. Although, of course, much depends on the design of the keyboard itself (Some specially protected, and such a problem do not have such a problem) .

In any case, from time to time I recommend to clean the keyboard from the garbage (it will not be too much).

How can I clean the keyboard:

  1. Method number 1. : Use compressed air cans, which are sold in most computer stores (or by a conventional vacuum cleaner, turning on the reverse mode). With the help of such a simple "blowing" you can get rid of most dust and crumbs from under the keys. Squeezing

  2. Method number 2. : Now in many stores (for example, Chinese) sold specials. Keyboard cleaning vacuum cleaners. Also a very good and convenient means (an example of such a device - see photo below 👇). USB keyboard vacuum cleaner

  3. Method number 3. : Also in many stores now there are "spreading" velcro. The principle of working with it is quite simple: first you put it on the keyboard, slightly attach it - it spreads and fills all the emptiness between the keys, all dust and debris sticks to it. Then replete it along with the garbage.

  4. Method number 4. : If you have a regular keyboard (not a laptop) - you can simply turn it over and knock on it slightly, shake. Even this way helps to "knock out" a lot of too much of it ...
  5. Method number 5. : If you are a little familiar with the technique, you can try to disassemble it and blow from the inside, manually wipe and clean (I note that the operation requires some experience; do at your own risk) .

Wear and boiling tracks (especially relevant when the keyboard is influence)

For reference!

Conditionally keyboards can be "split" for 2 camps:

  • membrane: in which thin films are used with tracks);
  • Mechanical: where each individual button is "Button".

The most common membrane type keyboards (about 90% -95% on the market). They are cheaper and easier (which is especially relevant for laptops).

So here Which keyboard was not - it is designed for a certain number of presses (as a rule, several tens of thousands are several years, even with active use).

Over time, the conductive paths are crying, thin contacts, closing tracks, wear out, also makes their "case" and dust.

By the way!

The process of "crying" conductive tracks is accelerated hundreds of times if you 👉 Solo some fluid on the keyboard. What, by the way, not so rarely, the specialists abroad considered that every 100 mug above the keyboard overthoe on it ...

Membrane keyboard

The membrane keyboard (as an example, to understand what it was about).

When problems with the old keyboard (either with a flooded, some kind of liquid) I can advise the following recipe (He does not guarantee recovery, and do it all on his own fear and risk. However, a few keyboards revive for a while, he helped me) :

  1. first remove (turn off) keyboard from a laptop (from PC);
  2. If the keyboard is filled with some kind of liquid (lemonade, tea, etc.): well rinse it in warm water with a detergent (for example, Fairy) and let it dry. Connect again and see if it began to work normally;
  3. If the option does not help, you will have to completely disassemble the keyboard, and wipe the film with tracks and the elastic membrane using ethyl alcohol.
  4. Pay attention to the status of the tracks: if there is somewhere suspicion that they "extended" or damaged - they need to be processed using conductive glue (it would not be "ringing" the track to determine whether it conducts "signal" / current); Or simply accept and buy a new one ...

  5. The method of though "collective farm", but sometimes helps to restore the keyboard. By the way, it is suitable only for the membrane type of keyboards.

How to do without some buttons

It is not always possible to replace the keyboard: sometimes it is trite there are no funds, often many get used to their keyboard that simply do not want to change it to any other. As for laptops - it can be so to become that the desired keyboard can not find the desired keyboard ...

But in many cases, you can do without non-working keys (especially if there are only 1 ÷ 2). The most popular ways of this "bypass" will give below ...

You can reassign one key to another

The most common option is to use special utilities that can be replaced by pressing one key to press on another. Sounds a little "strange," but the principle is:

  • Does not work with you, say, key "z";
  • You install the "Ctrl" key together;
  • Now, when you click on "Ctrl" - you will have a "z" (I draw attention that you can reassign almost any buttons with each other).

The principle of working with it is very simple: first indicate which button you want to use instead of non-working; Then you specify not working and save the settings. After restarting the PC / laptop - "Case" is done, the key will be replaced (the screen is slightly higher).

You can connect an additional keyboard

Also, like the PC, you can connect a regular keyboard to any laptop (most often the classic USB keyboard is used). As a rule, there are no problems with the setting: the keyboard becomes available for work immediately after connection.

Damage to the keyboard for a personal computer is, of course, unpleasant, but not critical for the entire device. The keyboard on it can be replaced. As for the laptop, it will not pass such a number. In case of damage to the keyboard, you need to either repair or purchase a new one.

Some buttons do not work on the laptop keyboard

Why do not work buttons on the keyboard laptop

The reasons for such a breakdown can be different. Here are the main of them:

  • The defective device is the simplest reason. Now it is found quite rare, but still takes place. It is manifested immediately after purchasing the device. One or two buttons can not work, rarely - completely. It is recommended to return such a laptop back, from where they brought.
  • Error in the operation of the system - the operating system installed on the device does not cope with the load. Despite the fact that the computer industry develops for a long time, the computing machines still work unstable. An error may occur due to hardware imperfection or due to viruses. Signs of such ailment - the entire keyboard is disabled, perhaps not only she. Reboot and subsequent cleaning of a computer will help to cope with the trouble.
  • Chip damage or fees are a more complex problem. It affects the physical shell of the device. To find out if your case should check your charger entry, USB input and touch panel. If they do not give signs of life - it means that you need to go to the service of techwork. Perhaps the chip will be damaged in part, which will explain why half the keyboard on the laptop does not work.
  • Plue damage - problems with interaction between the hardware and the monitor. This reason is manifested by a sharp disconnection of the keyboard, but in good job of other elements of the laptop. You can try to open the laptop yourself and fix the loop.

ATTENTION. If you have never had to disassemble electronic devices - tablets, laptops, system blocks of computers - and you are not sure that you can do everything right, it is not recommended to conduct experiments with your laptop. It is better to provide an opportunity to a specialist to deal with trouble.

  • The lack of drivers is a rather rare cause. In most situations, the keyboard on the laptop does not require additional software. This problem is solved by removing old drivers and installing new ones.

Partially does not work Keyboard on a laptop

Some buttons do not work on the laptop keyboard

The situation when not the entire keyboard ceases to work, and some keys are not as often. Most likely, these are foreign objects. The presence between the buttons pieces of food or liquid explains why the keyboard on the laptop does not work. Even if the user does not have a habit of chewing behind the monitor, all the same over time the dust is stuffed between the buttons. You can disassemble and clean yourself, but can be attributed to the technical support center.

What to do if some buttons do not work on the laptop keyboard

The answer is simple - try to correct the breakdown yourself or attribute to the service so that the specialists "cured" there. Below will be presented options for self-repair.

Simple ways to solve the problem

The keyboard has its own blocking. It is possible that the user accidentally blocked his keys. Depending on the modification of the device, in order to unlock the buttons, it is necessary to clamp Fn + Numlock, Fn + Pause, Fn + Win or a special button with the image of the lock, if it is. If the buttons then start working, it means that the problem was solved.

Alternatively, you can try to clear the keys to the tassel, or use the special vacuum cleaner intended for the keyboards. Such an event will help get rid of the problem if the laptop has been driving dust and the key from the keys to the system does not pass.

Some buttons do not work on the laptop keyboard

Fix the program failure

Simple ways did not help, it means you need to try to solve the problem at the program level. Incorrect work of programs or driver can affect the response of several buttons or the entire keyboard. List actions for verification and correction:

  • Run the laptop and when the first window appears to press F8. It is not always this key that calls the download menu, different keys can be used in different versions of operating systems. If the F8 did not bring the result, you should try to press other F. The result must serve the "Additional Download options" window.

Software

  • Using arrows or additional navigation buttons at the screen (rare laptop models are supplied with them), select "Safe Mode" or "Starting in Safe Mode". This will allow you to start the system without using drivers.
  • It remains to check the performance of each key on the laptop, regardless of which of them worked before, and which are not. It is enough to use the online keyboard buttons service. To find it, just enter in the Key-Test search engine and choose the first link. In such services, each pressed key is displayed, which will help to easily check the condition of each button.
  • If the buttons in safe mode show a good job, the fault really lies in the system. In this case, step further on the list. If some of them are not triggered, or they are unstable, then the software shell is needed.
  • To correct system problems, you can try to update the drivers. Running the system in normal mode, in the "Search" menu "Start" enter "Device Manager". If the required letters on the keyboard do not work, you can try to enter a similar request in the browser search engine, and it will correct errors, after which you copy the corrected option (Ctrl + C by default) and insert in the search field (Ctrl + V). Or just from any text on the Internet copy the necessary letters and use them.
  • From found items to choose the desired service.
  • NotebookA window will open in which to select the keyboard item and selecting one of the items, click on the right mouse button. A list will fall out, where the user will be useful to "update drivers". After that, the question of searching for drivers, where you need to choose "Search drivers online".
  • These actions need to be repeated for each position if there are several of them. Some keyboards are indicated by several names, but it rarely occurs.
  • If the system has decided that new drivers are not required, then you should remove the old and download new software. This can be done in the same place in the device manager by selecting "Delete" in the drop-down list.
  • After that, the automatic installation of the drivers on the keyboard should begin. If this did not happen, turn off the laptop and turn on again. The system will detect a new device without drivers and try to install them.

Updating drivers is also possible using a variety of programs that independently detect all the provision in the system that needs to be updated. If, after reinstalling the drivers, the problem with non-working keys is not solved, it means that the problem is not in the program sphere.

Fix physical failure

This option provides for disassembling the laptop and eliminating the physiological cause of failure. If you are not able to disassemble and properly collect an electronic device, do not risk better, and contact a specialist. The sequence of actions is as follows:

  • Fully turn off the laptop and remove the battery. The battery is usually located at the bottom of the device, closer to the joint of the monitor. The laptop at this moment should not be connected to the power grid, and, in general, it is desirable to remove all additional devices from it.
  • Complete the top plate with a simple screwdriver, needles, knife, or any other narrow item. The latches are located at the edges of the site with the buttons, you can find them quite quickly. If there are no snacks, you should pay attention to the instruction that went with a laptop - it is possible that it says how to open a laptop.

Physical failure

  • Immediately twink the plate with the buttons is not necessary - it is attached to the rest with the help of a loop, and harsh movements can damage it. The plate should be carefully lifted and, while taking care of the plastic portion of the loop, disconnect it from the rest of the laptop. If there are noticeable damage on the loop, it is necessary to replace it (most likely, the problem is in it). Troat the location of the loop with wires is categorically not recommended - only plastic.
  • The plate covers the microcontroller. This is a special tool that provides the transmission of the signal from the buttons to the PC reader. If dust or humidity is noticeable on it, these factors need to be eliminated - they can cause poor laptop operation. Learn the microcontroller is easy - this is the item on which the loop was attached. If you have a noticeable damage to the unarmed eye, you need to be replaced.
  • After that, you need to disconnect each key individually (the same thin object that was used to open a laptop), then clean the surface of the plate. If there are damages on the buttons, it is better to replace them - buy spare.
  • After complete cleaning, you need to repeat all the actions on the disassembly of the laptop keyboard in the reverse order and check the operation of the buttons. If it did not help, it is better to use the technical support of specialists.

Physical failure

How to do without some buttons

If you solve the problem with several non-working keys there is no possibility, then you will have to use any time as it is. Options for compensation missing letters:

  • Create a text document and copy the necessary letters there from the Internet, and copy them from there as needed.
  • Use the automatic adjustment of words in Microsoft Word or Internet resources.
  • Download the virtual keyboard, or find such online.

In any case, the absence of some keys does not yet put the cross on the entire laptop. In most situations, the problem can be solved or adapted.

Some keys on the laptop keyboard stop working

Cause 1: Keyboard Mode

If you do not work key blocks F1 - F12 or a digital block, just change the keyboard mode.

Cause 2: Keyboard Pollution

The most popular reason why some keys on the keyboard, located in random order, cease to be accommodated - its pollution. At the same time it can be different:

  • The gear hit the key, for example, crumbs, dust, hair;
  • The keyboard was spilled liquid;
  • The julp key, again, most likely, because of the fluid that fell inside.

Stripping from the cause, you can already navigate what to do. With just a dirty keyboard (sometimes the steers are not visible externally, but if you remove the button itself, the remnants of the food, animal wool, accumulated dust and fat) are quite clearly cleaned and check whether the key is pressed.

If the keyboard flooded with liquid, it could very seriously suffer. In any case, it will take it to disassemble and clean the contacts from the residues of liquid, oxidation and other negative consequences. However, it is worth understanding that this is not always effective, because to provide "help" a component needed immediately after spilling fluid. At best, the keyboard can be corrupted, in the worst - the liquid fell on the motherboard and spoiled it. In more detail, we considered the situation with the fault below. Cause 6. .

In the presence of knowledge and confidence in your abilities, you can disassemble the laptop on your own and clean the keyboard. Everyone who has never come across such an operation and is afraid to break something, it is better to contact the service center. Tell the master of the problem - you may be able to get rid of the trimming of the affected areas.

The poured keys are usually there from spilled liquid type of sweet tea, but sometimes there are a consequence of other reasons, so be sure to check the operation of all keys that are not related to letters and numbers - maybe some of them do not give normally the rest. It is best to do this through special online services.

Cause 3: Software errors

Often, problems with clicking some keys calls the software installed on the user's computer. It is not possible to list such a software possible, so the user will have to independently understand whether any of the established, especially running, programs adversely affect the keyboard. For example, some people stopped accommodating random keys even after installing the driver for the GeForce Experience video card. That is, as you understand, the culprit of the problem can even become the software that you will not think about checking under normal conditions.

First of all, the "Anamnesis" is important: remember that you were installed or updated quite recently. It is likely that some of the installed programs and turned out to be a source of malfunction. Stop her work, and if it did not help, make a "clean" launch of the operating system:

  1. Keys Win + R. Call the window "Run" Where write msconfig and then click ENTER or "OK" .
  2. Call Application System Configuration when searching for the cause of broken keys on the keyboard

  3. Being on the tab "Are common" Select option "Selective launch" and leave a tick only item "Download system services" , Secondly remove.
  4. Clean Windows Starting through the System Configuration application when searching for the cause of non-working keys on the keyboard

  5. Switch to the tab "Services" , Install the checkbox at the item "Do not display Microsoft services" , then click "Disable everything" . Now restart the computer and check if the keys work. If yes, look for the culprit among the disconnected services, selectively including some of them.
  6. Disable the start of all services through the system configuration application when searching for the cause of non-working keys on the keyboard

When unsuccessful loading, the problem should be searching among autoload records. Windows 7 users, being in the same application, can go to the tab. "Autoload" and click on the button "Disable everything" .

Applying a clean download to the autorun list in the snap-in configuration of the system in Windows 7

WINDOWS Windows 10 will have to open "Task Manager" For this purpose, for example, keys Ctrl + SHIFT + ESC . In it, go to the tab "Autoload" Remove from download Absolutely all programs that do not affect the performance of the PC (most likely, this is the entire list of autoloads). To do this, select the mouse every process and click on the button "Disable" .

Disable the program startup when searching for the cause of non-working keys on the keyboard

N1 may cause an unsuccessful update of the operating system. If it was just recently produced on a computer, roll back the update. In the "dozen" there is a convenient feature:

  1. Open the application "Options" .
  2. Go to parameters to roll back the last installed update when searching for the cause of non-working keys on the keyboard

  3. Go to section "Update and Security" .
  4. Go to roll back the last installed update in Windows 10 when searching for the cause of non-working keys on the keyboard

  5. Through the left tab, switch to "Restoration" where you will see the block "Return to the previous version of Windows 10" . You have 10 days from the moment of installing the update, after which the refund will be unavailable. Press immediately "To begin" to start a rollback, or first learn about this action more using the link button "More" .
  6. Rollback of the latest installed update in Windows 10 when searching for the cause of non-working keys on the keyboard

Cause 4: Virus

Very often viruses in this way violate the performance of the computer. Cases when it is the malicious software that did not allow the user to normally type the text or perform other actions, are relevant annually, so we strongly recommend checking your computer using protective software. For a reliable result, it is preferable to use third-party programs, and the defender does not fit into the system. In more detail about which utilities and applications for this goal are best suited, we told in another material.

Cause 5: Marriage

If the laptop on which the keys do not work, a new one, with a large share of the probability, you can judge that the defective instance caught you. Of course, it is worth understanding that even on a new laptop, a virus may be due to the user's inattention, or he could already pour it, such as water. We are not talking about this, but about the device, which has become incorrectly functioning almost immediately after purchase or after a short term with a very careful physical and software operation.

In the presence of warranty status, be sure to contact the store in which the device bought. It can be diagnosed or send you to a service center, where the laptop will be taken as in the same way to check. In such a situation, everything you have to do is wait for solutions from specialists.

The same rules concern and devices that, on the contrary, were just driven from SC. As a result of the error during repair or assembly, the keyboard could suffer (most often its train), and the correctness of this should be done by the masters that allowed the oversight. Therefore, in the same way, please contact where the laptop has previously passed for repair, "this defects are obliged to fix it for free.

Cause 6: Hardware Malfunctions

One of the most popular causes of problems with the keyboard, it is the hardware problems that arose both by themselves during operation and after any influences from the user. Next, we list the list of possible situations that could adversely affect the accessories.

  • Motes with loop. The train is a cable connecting components with a motherboard, and it could be damaged for various reasons. Often he just moves out over time, and then it is necessary to disassemble the laptop and reconnect it. The loop can be launched, because of which the signal quality suffers and some keys cease to live. The listed cases are the consequence of the negligent factory assembly, manifest us, as a rule, at the initial stage of the use of a laptop, and do not need to make a correction of the lack of independently - pass the laptop under warranty. You can reconnect the train of the old device yourself, if there are sufficient knowledge, and in absence, refer to the masters.

    It should be borne in mind that the loop can close or partially pull out, and then it is most likely to change along with the keyboard. Experienced users sometimes correct the loops themselves without fully replacing the keyboard, but if you do not belong to this category, we recommend not experimenting to accidentally not disturb the performance of the entire laptop.

    Example Laptop keyboard with loop

    The train may well be damaged in the course of user intervention, for example, when a person disassembled a laptop for other actions and did not fully connect the loop or incorrectly laid it (it is necessary to monitor the cable to be fixed in the connector), which is why he began to change it. Of course, nothing remains here how to proceed to repeated disassembly and thorough assembly. Additionally, we recommend using double-sided foamed scotch, placing the place of bending. Other features of the correct laying are looking for in videos devoted to the competent assembly of laptops - this will help significantly reduce the likelihood of wear.

    Neaxorate actions and excessive physical strength when disassembling a laptop also lead to damage to the cable, forcing a person to engage in its repair or fully change the keyboard. If you shed liquid, the loop could also be damaged that in most cases it causes the need to replace the entire keyboard.

  • Motherboard problems. In the absence of visible problems with the loop, it makes sense to check the motherboard. Usually it happens to feed power failures, and any device, including the keyboard, can suffer because of this. Indirectly confirms this and the behavior of the laptop as a whole: if you are encountered with its unstable work, for example, unexpected shutdowns, it actively signals that it follows the root of the problem in the motherboard. Nevertheless, only a specialist can diagnose such a specialist, and we all just advise to contact the SC.
  • READ ALSO: Major faults Maternal maternal diagnosis of computer motherboard

  • Faults of other elements. This can include the natural wear of the loop or the oxidation of conductive tracks (most often as a result of the influence of the laptop with a liquid), breakdown the button on the keyboard. The latter is rarity with several non-working keys, but it is quite real, if you have dropped something heavy on the keyboard, hit it or tried carelessly to remove the caps for cleaning the trash from the garbage. Those who wanted to do without qualified intervention defective tracks can be tried to fix it properly, for example, using conductive glue or other technicians. With the keys, everything is much more difficult, since it is often very difficult to fix the design, and if you do not have enough skills or such an opportunity is missing, it is easier to give a laptop to repair, or buy a used keyboard from the same model of the laptop selling in parts, And gently replace some keys.

  • Developed resource. It is worth understanding that any technology has its own limit of service life, and if you do not have a new laptop, and you used the keyboard often, it is likely that it has already just taught the term laid. Repair there is usually nothing, it is easier to replace it with the same new one.

Additional Information

In addition to the basic information, we also want to emphasize that occasionally may affect the performance of the keyboard, as well as how to use a laptop before replacing the keyboard.

Specific methods for checking the keyboard

Since the situation under consideration is caused by both software failures, it is necessary to fully eliminate this suspicion or confirm it and do not move to more complex and costly hardware diagnostics.

  • If the keys that can be used in the BIOS, check them there. This, for example, arrows, F-row, ENTER, +/-, ESC or keys to enter the BIOS. When the specific key does not respond even in BIOS, with a greater probability, it can be judged about its hardware fault.

    See also: How to enter BIOS on Acer / MSI / Lenovo / Samsung / ASUS / Sony VAIO / HP laptop

    However, this can occur due to "crooked" of established BIOS updates. If you recently updated his firmware, there is a chance that it was the cause of the failure. The first thing that makes sense to try, - reset its settings.

    Read more: Reset BIOS settings

    The second is to return the previous version.

    Read more: BIOS rollback to the previous version

    We want to warn you about the unsafe of these actions. You are engaged in the firmware and risk, and possible consequences can lead to the fact that the computer simply does not turn on. Be sure to find out more information about the BIOS update procedure to secure it.

  • If you have or your acquaintances, any keyboard with a USB or Bluetooth interface, use it literally at the time of checking. By connecting an external device, start pressing those keys that are not accommodated on the built-in keyboard. If they function, apparently, the malfunction is hardware, and not software. You can also work with it for a while until you give a laptop for repairs.
  • If you have two OS on a computer, you must start the second system and check whether there are problem keys. For this purpose, any distribution system is also suitable for this goal, starting from the flash drive. Another option is to use the loading flash drive by booting with which you can not reinstall OS, but open, say, console in the recovery environment and check the keys there.
  • Reinstall the keyboard driver. The recommendation is rarely helped by someone, but it is still worth performing it. There is a small chance that the driver files have been damaged due to a hard disk problem, or incorrectly downloaded / installed.
    1. Open "Device Manager" , having found this application through a search in "Start" Or clicking the right mouse button on it.
    2. Launch Device Manager when searching for the cause of non-working keys on the keyboard

    3. Expand section "Keyboards" : Most likely, there will be only one item in which you need to click on the right mouse button and choose "Delete" (or "Delete device" ).
    4. Deleting the keyboard driver from the device manager when searching for the causes of non-working keys on the keyboard

    5. Confirm the action, and then restart the laptop. When you turn on, the driver must be installed automatically, and when logging in to the system, you can check the keys.

Using a screen keyboard

To be able to use non-working keys to repair, it is convenient to run a virtual keyboard. It is already built into the operating system, and you can even call it before entering your account if the password is installed on it and it is not physically unable to enter it. In the link below, you will find information on how to open it and use on a laptop with any version of Windows.

Key reassignment

Another option is to reassign the function of the non-working key to the operating. It is more suitable for long-term use, since the reassignment process itself may not be from rapid, or if you need to print a lot, and every time you call a virtual simplicity is inconvenient. In addition, not everyone wants to contact the service center if the pair of unpopular keys does not work.
