The wireless keyboard on the computer stopped working. Why isn't the keyboard typing? Possible causes of malfunctions and their elimination. My keyboard doesn't work; letters are not written

Sometimes users face such a problem that part of the keyboard on a laptop does not work for them.

In principle, it happens that the entire keyboard does not work at once, but then, most likely, it just needs to be replaced. But if only some of the buttons cease to function, everything is somewhat more complicated.

We will consider everything that can only be done in this case on our own, without the involvement of specialists.

Simple ways to solve the problem

It is not always necessary to do something difficult in order to restore efficiency. The problem is often solved quite simply.

So from the beginning, do this:

1.Try pressing 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, this simple method allows you to start the full keyboard operation.

3. Take a brush and run it over all the buttons. It is possible that some kind of dust has accumulated under one of the buttons. Bring a vacuum cleaner if possible. On the Internet, you can find special vacuum cleaners for small keyboards.

4. Restart your computer. In some cases, there may be some minor bug in the system that prevents certain buttons from working.

In most cases, the problem will be minor and can be fixed by one of these actions. If all else fails, proceed to the next step.

Fixing a software glitch

It is possible that the problem is in the malfunctioning of some programs or services. To check this option and, you need to do the following:

The best way is to do it the standard way:

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

Device Manager in Control Panel

• open the "Keyboards" item;
• usually there is only one keyboard, right-click on it and select the item "Update drivers ..." (if there are several keyboards, which is very unlikely, do the same with all);
• select item "Automatic search ...";
• wait until the drivers are found on the Internet, they will be installed automatically.

Updating drivers in the standard Windows way

You can also download and install the program. It allows you to scan your entire computer for the latest available drivers.

If the keyboard has incorrect (roughly speaking "broken") or irrelevant drivers, you can easily remove them. Using this program looks like this:

• download the program ();
• install it and run;
• an automatic scan will take place, after which just click on the "Update All" button.

Read about other good similar utilities at.

If updating and scanning your drivers doesn't help, try rolling your system back to a point where everything worked well.

To do this, you need to do the following:

• open the "Start" menu, then "All programs", "Accessories";
• after that go to the "Service" section and click on the item "System Restore";

"System Restore" item in the "Start" menu

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

Selecting a restore point for system rollback

• click Next and then Finish.

In principle, you can roll back the system even in those cases when the keyboard also does not work correctly in safe mode.

But in this case, the likelihood that it will help is very small.

Most likely, the problem is already mechanical, not software, and it needs to be solved by physical intervention in the computer device.

Fixing a physical failure

In this case, you will have to look step by step what could go wrong there.

To do this, follow these steps (it is very important to adhere to the order in which all the steps will be listed below):

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

2. Take a flat-blade screwdriver and gently slide out all the latches on the plate that holds the keyboard. If you do not see any latches on your laptop, you should take the instructions in hand and read what it says about the keyboard device and how it is removed. In any case, some kind of fastening mechanisms must be present.

The process of opening the keyboard plate latches

The keyboard plate is attached to the laptop itself with a ribbon cable. You will see it immediately.

3. So, if there are obvious damages on it, the loop just needs to be removed and replaced with a new one. To do this, take an old ribbon cable, go to your nearest electronics store and buy the same one.

Keypad loop

4. If the ribbon cable is not damaged, it must still be removed. In this case, the loop should not be taken by the conductors in any case! You can only take on the plastic parts that attach it to. For clarity, Figure 10 shows the parts that can be tackled and those that cannot be tackled. True, keyboards usually use slightly different cables.

5. In the same place, under the keyboard plate, you can find a microcontroller. It is necessary dry and try to draw out the dust using a vacuum cleaner.

Explaining how to find this very microcontroller is quite difficult. To put it simply, this is exactly the device to which the loop is attached. Just in case, when removing the keyboard, go over all the controllers you see. Without special knowledge, nothing else can be done on your own. Again, if you see obvious damage on the microcontroller, it is best to replace it.

6. If everything is fine with the cable, you will have to disconnect the keys and clean them. Usually the button can be removed in the standard way - pry off with the same flat screwdriver. Start with the problematic buttons. If you see damage underneath, replace the parts that secure the button to the laptop.

The process of removing buttons from the keyboard

7. Try using the keyboard again.

If the problem persists, remove all buttons and remove the aluminum plate that is underneath. Usually she also has special mounts that can be removed quite easily.

But under it is a plastic board with painted paths.

Examine it for any obvious damage - if any, there are two options: draw new tracks or buy a new board. Either way, vacuum the board over the board.

Checking the integrity of the tracks on the keyboard board with a tester

To draw the tracks, use the car rear window heating thread repair kit (that's what it's called).

If all else fails, your best bet is to have your computer repaired.

Part of the keyboard does not work on a laptop: what to do and how to fix it - detailed guide

Without a keyboard, we cannot imagine the full-fledged work of a computer, because this is one of the main components of a PC. If the keyboard is broken, the source of the damage must be found.

Why is the keyboard not working on hp laptop, lenovo and others?

Software glitch
You should not carry it to repair if your laptop keyboard does not work. Perhaps the keyboard is simply not activated in the laptop's settings, so the laptop does not recognize it. Follow these steps to fix the problem:

• You need to go to the "Device Manager", then click on the "Keyboard" tab. You will need to see if it is activated or not. If not, then correct this nuance.
• A reboot can also fix the problem.

Viruses
One of the reasons may be the presence of viruses in the laptop. If you installed the application, and then your keyboard stopped working, then you should conduct a deep scan with an antivirus to find all malicious files. Then move the viruses to quarantine or completely delete and restart the computer. The keyboard should work.

Drivers
Often they are faced with the fact that the keyboard on a laptop does not work, and the reason is outdated drivers. This is the simplest case that every user can handle. You need to update the driver and restart the computer and the keyboard works again.
Physical problems.

This problem is very serious as it can cover a wide range of reasons. The matter may be in the contamination of the contacts, which prevent the contact of the plug with the computer, or buttons and microcircuits, which will only need to be changed in diagnostic centers, may be damaged. Broken contacts can also be the cause. If the user was not careful and pulled the cord, then there may well be a breakdown of the contact and socket.

How can I tell why my keyboard has stopped working?

There are three easiest ways to check this! Let's analyze each in detail.

Check contacts
Perhaps they just moved away from the computer. Especially if there is a pet, then it could catch on the cord. This is the most common problem. Just stick the plug harder and it should work. If that doesn't work, then try sticking out and pushing the cord back in, as the computer sometimes malfunctions. If this did not help, then we turn to the second reason, which will help to solve this issue.

Check your computer for viruses
Try to scan your PC for malware. Use only licensed versions of antivirus software, such as: Kaspersky, Avast, Doctor Web. They will definitely be able to help get rid of viruses. Perform a deep cleaning of the entire computer, after which all viruses must be moved to quarantine and removed. After restarting the computer, the keyboard should work. But viruses are not always to blame.

Each driver becomes outdated sooner or later, which means it needs updating. There are two ways to update the driver: download a new one from the Internet, which will be convenient for users who have an Internet connection.

And the second way is to install the driver from the disk that came with the computer upon purchase. The driver is installed as a normal game, after which it requires a computer restart. The keyboard should work. Follow the next advice, it is useful for every PC user: download DriverPack Solution or DriverDoc from the Internet. These programs will be able to automatically install drivers for you when you connect to the Internet. To check for drivers on your computer, follow these steps:

1. Go to the start menu.
2. Click on the "Computer" tab with the right mouse button.
3. Go to the "Management" tab, which is protected by the administrative rights of the computer.
4. Go to Device Manager.
5. Click on the "Keyboard" tab, then right-click on the keyboard.
6. Click LMB on "Update driver". With these programs, it will automatically update to the latest version.

After that, the keyboard should work. Repeat this action every one to two months.

What to do if the keyboard does not work on a windows 10 computer?

In this case, two main problems can be distinguished, for which the keyboard may not work.

1. This is a problem in the Windows 10 operating system itself.
2. A problem related to defects in your computer or laptop.

You can hardly do anything without a keyboard, so use the temporary on-screen option. Go to "Options", go to "Accessibility" and select the "Keyboard" tab. Move the circle in the On-Screen Keyboard to turn ON.

Check the plugs and connectors carefully, they may have been damaged. Try plugging the USB plug into a different port on the back of your computer, it might be the problem.

The ribbon cable can be damaged in the laptop, so do not try to fix the damage yourself. It is better to take the laptop to a service where specialists can see it.

OS configuration
In order for you to finally find out the problem in the computer or keyboard, you need to go into the BIOS, since it does not interact with the operating system in any way, but is involved with the motherboard. If everything works in your BIOS, then the problem is already in the operating system itself. If the keyboard and mouse do not work already during the installation of windows, then the problem is in Windows 10, and not in the devices. And if the keyboard does not respond in the program, then there is already a problem either in it or in the computer itself. For reliability, you can ask your friends for a keyboard to try it yourself. To fix this problem, try:

1. Restart BIOS several times.
2. Go to "Control Panel", then to "Troubleshoot Windows" (in particular, the item "Keyboard" or "Hardware devices"). In Device Manager, remove the keyboard). In the "action" menu, click on the "Update computer configuration" icon. Everything should work.
3. Make sure that you have the "Num Lock" key enabled when entering your password. This can be determined by the indicator on the keyboard (if it is lit, then the key is on).

Clean from dirt / dust
Perhaps the sockets into which the plugs are stuck are simply clogged with dust, therefore they prevent the contacts from interacting. To do this, just disassemble the computer, it is advisable to work with soft brushes. You can use a vacuum cleaner that has a blowing function. In most cases, this method is very effective. Do not try to pick up the dirt with something, take a special wet napkin, which is sold in any computer store. Use it to remove dirt.
What if the keyboard does not work in assassins creed origins?

Many have faced the problem that the keyboard has stopped working. There are two options. The first is to try to start the game not through a shortcut on the desktop, but through the main folder with the game. Restarting the game doesn't hurt either, because there are times when it helps. The second option is to close the Discord program as it interferes with the functioning of the keyboard. Computer power has nothing to do with it. Of course, you can assume that the problem is with the game files, and if you have deleted something recently, then be sure to double-check.

Wireless keyboard and mouse not working

If the wireless keyboard does not work, then first of all check the battery and replace it if necessary. Do the same with the mouse. But if after that the keyboard and mouse do not work and you are sure that the battery is full, then find working devices and go to the control panel, go to "Devices and Printers". Then press RMB and press "Connect device", well, or confirm the action. Remember to restart your computer.

First of all, check the plug in the socket, whether the keyboard is connected correctly. If the computer is outdated, then the BIOS version will also be old, because of this, the device may not recognize USB devices. Go to the "USB Keyboard Support" section and look at the inscription. If it says "Disabled", then the device is disabled, change to "Enabled" and everything will be connected.

If you have multiple PCs in your home, try the keyboard on another PC in the BIOS program. If it works, then the problem is with your computer. Some programmers take the battery out of the motherboard for a few minutes, then the BIOS is reset to factory settings, but an inexperienced PC user is not recommended to do this.

What if the buttons on the keyboard don't work?

Try to carefully remove the buttons and clean them from debris, as they may not work for this reason. The keyboard buttons are connected by thin microcircuits that can be easily damaged. Viruses are unlikely to be able to harm here, so if nothing helps after cleaning, it is better to replace the keyboard. There is an option to try a different keyboard on your computer. If it works, then the problem is in your previous device. The same can be said for the number buttons. Try to be more careful when disassembling the keyboard.
If all else fails, but you urgently need to print the text.

If this happens, then use the onscreen keyboard. Go to the "Computer" menu, then go to "Local drive C", then go to the "Windows" folder, select "System 32/64", depending on your computer and open the "osk" file. This will be the on-screen keyboard. You can print it with the mouse.

Keyboard testing programs

To your attention there are a number of programs that test your keyboard for performance.

• Key-Test;
• Keyboard-Test.

These programs will easily help you determine whether your keyboard is working or not. Applications are publicly available, you can download them from the Internet. Installation will take you no more than three minutes.

Failure of any of the elements of the computer's peripherals means the difficulty or complete termination of the entire set. If the keyboard does not work, then work with the computer becomes impossible, since the possibility of data entry disappears. Using the on-screen keyboard does not solve the problem, since its functionality is significantly limited and does not provide full-fledged operation. At the same time, sometimes you have to work right now and have no time to run to the store for a new device. Often times, the problem can be solved on the spot without resorting to drastic methods.

Why Your Keyboard May Not Work - Finding the Cause of the Problem

If any lights are on on the connected keyboard, it's not so bad. It is more difficult if the device does not show any signs of life at all. The first action to be taken is to determine the possible cause of the malfunction. To do this, you need to carefully examine the device, the connecting wire, check the connection and decide on further actions. Then you need to connect the problem keyboard to another computer. Also, it does not hurt to connect a known working keyboard to your computer and make sure that there are no problems with the software, the operation of the connection ports. Simply put, you need to figure it out - the keyboard does not work, or the problems lie in the computer.

Physical breakdown

Most of these problems have quite noticeable outlines - a broken wire, mechanical damage, etc. By the nature of the detected flaw, it is possible to draw an approximate conclusion about the fate of the device, although damage to the case does not necessarily mean the complete destruction of the keyboard. A more difficult situation is when the keyboard does not work, which does not have visible signs of damage. If the problem persists when connecting to another computer, check the condition of the connecting wire. Often, it breaks near the entrance to the device body or (less often) on the connecting plug.

The habit of holding a mug of tea, coffee or other drinks next to the keyboard disabled many devices

Software problems

If, when connected to another computer, the keyboard works normally, then the reason most likely lies in the software. You might need to install or update a device driver. First of all, you need to check the state of the keyboard in the device manager. In Windows 7, to do this, right-click on "computer" in the "Start" menu. In Windows 10, it can be opened by typing "device manager" in the taskbar search box. If the “keyboard” item contains the name of the problematic device without additional icons (usually a yellow triangle with an exclamation mark), then the system sees it and does not find any problems.

Other reasons

Snackers while working on a computer often spill various liquids on it. The habit of holding a mug of tea, coffee or other drinks next to the keyboard has disabled many devices, but it will probably take a long time to eradicate it. Usually, traces of spilled liquid remain on the surface, even if they were wiped off in time. Symptoms of such a malfunction are the lack of a normal reaction to some buttons, sticking of individual buttons, and erratic commands from the keyboard. She often starts typing one letter endlessly or executing a command.

Batteries are a common problem with cordless samples. When their capacity begins to drop noticeably, the operation of the device becomes unstable and at some point stops completely.

What to do if the keyboard does not work - solving the problem in various ways

Problems with the keyboard are in most cases surmountable. The procedure depends on the specifics of the problems encountered and is selected in accordance with their scale. Let's consider a possible algorithm of actions in this or that case.

Repair or replacement of the keyboard, connecting cable

Mechanical breakdowns of the device can be restored only with small amounts of damage. A broken case or similar major malfunctions leave no chance of success. The most successful actions can be cleaning the device from the penetrated liquid (sweet tea, coffee) or replacing the connecting wire.

For cleaning, you will need to disassemble the device. The keyboard is disconnected from the computer. All buttons are carefully removed, rubber transmitters are removed, stains from dried drinks are wiped off with a soft brush with alcohol. After finishing cleaning, the keyboard is assembled in reverse order. Particular attention should be paid to the installation of large buttons, which are not simply inserted into the corresponding slots, but are fixed with metal guides.

If there are no ready-made soldered plugs at hand, then the easiest way is to purchase a new keyboard and not waste time looking for the necessary parts or elements.

Repairs can only be carried out with skill and knowledge of the design. All actions taken at random do not provide positive results. If the essence of the breakdown that has arisen is unclear, then it is most correct to simply replace the keyboard with a new, serviceable one.

Typically, drivers for major peripheral devices are included with Windows. However, new items that are wireless or have a number of additional functions require their own software. The required drivers are supplied with the devices on CD-ROMs. In case of loss or absence, you can find the software of interest on the Internet and install it on your computer. There is also an easier way - to open the device manager, find the "Keyboard" item, right-click on it and select "update drivers" in the drop-down list. The system will find and install the software itself.

Typically, drivers for basic peripheral devices are included with Windows

Such a change may be necessary if you are replacing an old keyboard with a PC / 2 connector with a more modern one with a USB connector, or when connecting the device to a laptop. In the BIOS settings, you need to find the "USB Controller" tab and set the value "Enabled". Then you need to find the "USB Keyboard Support" tab (it can also be called "USB Legacy Support") and also set "Enabled". If you plan to work with the keyboard in DOS, you will need to enable the corresponding value in the "USB Keyboard Support Via" tab, although it is not available in all BIOS versions.

Such a change may be necessary if you are replacing an old keyboard with a PC / 2 connector with a more modern one with a USB connector.

Experts note that problems with USB keyboards are quite common. In order to avoid them, a PC / 2-USB adapter can be used. In this case, most problems are solved automatically, but the operability of the adapter must be checked.

Customizing the keyboard itself

The keyboard is configured in the control panel: "Start" - "Control Panel" - "Keyboard" - "Properties: keyboard". Can change:

1. The speed (frequency) at which the character is repeated while the key is pressed.
2. Delay before replay starts. The parameter determines the time it takes for the next character to appear when the key is pressed.
3. Blinking frequency of the cursor on the screen.
4. The default input language.
5. Layout switching keys.
6. Additional language support

The keyboard is configured in the control panel: "Start" menu - "Control Panel" - "Keyboard" - "Properties: keyboard"

Customization of the keyboard is usually not performed, since the usual parameters are initially set by default. However, as a result of some user action or system failures, the settings may change, so if any problems appear, it is recommended to install them in the required order.

One of the reasons for a device failure can be a virus that has entered the computer from the Internet or from an infected external storage device.

One of the reasons for the failure of the device can be a virus that got to the computer from the Internet or from an infected external storage device. If signs of unstable operation or complete failure appear, you must run a full scan of your computer for viruses. You can use your own antivirus program installed on your computer, for which you need to click on the program icon in the taskbar and click the "Check" button, for most antivirus programs it is on the main page and is clearly visible. You can also download and run the Dr.Web CureIt! or Kaspersky Virus Removal Tool. These are free programs that effectively detect threats that might be missed by the installed anti-virus software.

After completing the scan and removal of detected threats, the computer restarts

Upon completion of the scan and removal of detected threats, the computer restarts and checks the device's performance.

Checking the performance of the keyboard itself

You need to make sure the keyboard works. To do this, it should be connected to another computer and check its functionality. If the problem persists, the problem is with the device itself. If it starts to work normally, then a hardware or software problem has arisen in the computer. You should be one of the first to use this check option, although you don't always have another computer at hand. The ability to localize the problem can significantly speed up its solution.

Other

The color of the socket matches the color of the plug, for the keyboard it is lilac

Keyboard problems can arise for other reasons as well. For example, if you connect a PS / 2 device to a turned-on computer, you can damage the motherboard. Many users take this action too lightly, especially those who use a USB keyboard. It can be extracted even when the computer is on, but with old PS / 2s, this is not possible. It is necessary to turn off the computer in a regular way and only then disconnect the keyboard and connect another. In addition, they often include a PS / 2 plug and a nearby mouse jack.

In most cases, a keyboard that has stopped working can be restored or made to work again. The main question will be the feasibility of such restoration, how durable and reliable it is. The price of the new device is not so high as to waste time on a failed keyboard with unpredictable results. Therefore, after making sure that the reason for the failure lies not in the hardware of the computer or software, but in the keyboard itself, you should decide whether it is worth repairing it, or it is easier to buy a new one. Independent actions are usually performed due to lack of time or when there is nothing to lose, the attempt will not spoil anything. It is possible to return the keyboard for repair only if it is expensive, the payment for the restoration is incomparable with the price of a new device. In other cases, the most reliable solution is to purchase a new keyboard.

User question ...

Hello.

Help with one problem. The keyboard on my Lenovo B70-80 laptop stopped working out of the blue. The laptop did not hit, did not flood, did not hit - just after switching on, it does not respond to pressing some keys. What can be done?

Good day!

What is good about an ordinary computer in this regard is a quick change from one keyboard to another. Unfortunately, this procedure cannot be done so quickly in a laptop.

In general, it is extremely rare for the keyboard to stop working for no reason. Most often, the user guesses what the reason is (and sometimes keeps quiet). For example, quite often the keyboard is flooded with tea, water, juice; mechanical damage, etc.

This article will discuss the main causes of keyboard failure and what you can do to restore your device to working condition. So...

The keyboard on the laptop refused: reasons

What can be done to fix the situation temporarily

I want to start the article with what temporary measures can be taken in order to somehow type some characters, press the necessary keys (which may be needed during the recovery process).

1. Method number 1 - connect a USB keyboard. So that any modern laptop has several USB ports. By the way, if the USB ports also do not work, then this is a rather bad sign, it may indicate a failed mat. fee;
2. Method number 2 - call the on-screen keyboard. It is located in the section: control Panel / Accessibility / Ease of Access Center (see screenshot below).

1) Inattention / ignorance of the user

No matter how funny it sounds, but very often the keyboard "does not work" due to the ignorance of the user. For example, how many times have they complained to me that the numbers on the keyboard are broken, that no dates are entered, etc. - but the point is that the numeric keypad works when the key is pressed Num luck (by the way, there is often an LED on or above it).

So, if this key is not pressed, when you try to enter numbers from the numeric keypad, your cursor will jump, move, and not react at all.

If numbers don't work for you, be sure to pay attention to this key!

Note: some laptop models include a numeric keypad only by pressing a key combination: Fn + Num Lock.

By the way, one more point: regarding the function keys (F1, F2, F, 3 ... F12)... On modern laptops, for any of these keys to work, you need to press the FN key in addition to it. Usually, this moment is configured in the BIOS.

The screenshot below shows the "Advanced" section of a Dell laptop - in the "Function Key Behavior" item - it is possible to choose how the function keys will work: in the mode of multimedia buttons (turn down / turn up the volume, brightness, etc.), or in the normal mode functions (update the page, call help, etc.).

I will not consider in detail here how to enter the BIOS and how to configure it, but I will give a couple of links to articles from which you can get this information:

1. how to enter BIOS -
2. bIOS buttons for different laptop manufacturers -
3. how to reset BIOS settings -

2) Garbage under / between the keys

Dust, dirt, crumbs are very fond of accumulating under the keys of the keyboard, and in general, the keyboard gets greasy over time from greasy hands, fingers, even among rather neat users. Over time, some of the keys (usually starting from 1-2) cease to respond normally, they have to be pressed and pressed with force.

An article on how to clean your laptop / PC from dust. A link to the section of the article on how to clean the keyboard from crumbs, greasy marks and dust -

There are three ways to clean the keyboard (in my opinion):

1. use special USB vacuum cleaner, which can gently and gently pick up most of the crumbs from the keyboard surface;
2. use special Velcro, which, when pressed, fill the plane of the keyboard, and when you unhook them, all dust and dirt remains on them;
3. you can blow out the keyboard with a regular vacuum cleaner (especially if it has a reverse mode), and then gently wipe it with a damp cloth moistened with soapy water.

3) Software glitch, error while loading OS

If not a single key on your keyboard works at all (and you did not fill it, did not knock, etc.), then I hasten to assure you, in more than half of the cases, the software is to blame. For example, a driver conflict occurs, at the stage of loading your OS, or some kind of virus is picked up, etc.

The easiest and surest way is to try restarting your laptop first. It will not be superfluous to try entering the BIOS (see how this is done in this article :).

Note: if your keyboard works in the BIOS (and the fact that you entered it already speaks about it), then you probably have a reason in the software. In case of problems with hardware, the keyboard will not work anywhere: neither in BIOS, nor in Windows, nor in any other OS!

If, after restarting the laptop, the keyboard does not work again (and the keyboard worked in the BIOS), try rolling the system back to the state when it worked. Below is a link to an article on recovering Windows.

How to repair Windows 10 -

If recovery doesn't help (or you don't have recovery checkpoints) you can try. I also recommend paying attention to the drivers, about them below ...

4) Driver problem

Generally, keyboard drivers are usually installed automatically during Windows installation. But sometimes the following problems are observed with them:

• Some laptops have a somewhat non-standard keyboard with additional. functions - and for its full operation, specials are needed. driver. If they are absent, the keyboard may not work in full mode;
• A driver crash / conflict may have occurred on the system. This often happens with USB drivers, TV tuners, audio drivers, etc.;
• The keyboard drivers themselves may have been damaged.

- programs for working with drivers: search, update, delete:

5) Acidification of the keyboard loop contacts // loop damage

If the previous steps did not help, and the laptop keyboard also does not respond to any of your pressings, I recommend checking the flex cable. The following usually happens to him:

1. if you disassembled the laptop and disconnected / connected the keyboard, it is quite possible that the cable could simply not be inserted tightly into the socket. If this was the case, try reconnecting the keyboard;
2. just as often it is damaged when the laptop is not carefully disassembled (the wiring in the cable is thin enough and can be interrupted with one not careful movement);
3. the contacts of the loop, or the socket into which it "sits down" could oxidize over time and not give good contact. Try to gently wipe them with an eraser (as a rule, the contacts begin to become lighter even by eye, which means you have removed the oxidized plaque).

IMPORTANT! On some laptop models, it is far from easy to remove the keyboard: sometimes you may need to disassemble the entire device to the bottom! In general, usually, it is enough to unfasten a few latches with a screwdriver (see photo above), and raise the plane of the keyboard.

By the way, if your laptop is under warranty, use the service center. Your independent disassembly (including disconnecting only the keyboard) will almost certainly cause a refusal of warranty service!

6) Filling the keyboard with liquid

Some experts have summed up interesting statistics: every 50th circle above the laptop falls over on it. First of all, it is the keyboard that suffers. By the way, from my own experience, I will say that with any flooding, the keyboard suffers 100%, but the rest of the devices (under it) still have a chance to remain dry: it all depends on the user's reaction speed after the incident, and the amount of liquid spilled.

In general, liquid liquids are different. Especially dangerous for iron is a liquid containing salt or sugar: tea, juice, lemonade, etc. When such a liquid gets on the contacts and metal parts of the boards, the process of oxidation and corrosion begins, which destroys (in some cases, far from immediately, but true) iron.

What to do if the laptop is flooded:

1. turn off your laptop: you can immediately disconnect the power supply and remove the battery as soon as possible (the faster the better);
2. then turn the device over so that liquid begins to flow out of it;
3. dry the device for several days (earlier - the device simply will not dry out). For drying, do not use hair dryers, heaters, or other similar devices;
4. it is highly advisable to disassemble the device and see how far the liquid has penetrated. In general, of course, if you have never done this yourself, I recommend showing the device at the service center: even if your device works after drying, the remaining liquid (especially if it was aggressive: juice, beer, tea, etc.) will slowly and surely destroy your iron from the inside, causing corrosion and oxidation.

7) Mechanical damage

In general, by and large, there is nothing to break in the keyboard, and as a rule, the breakdown is associated with damage to a specific key (i.e. 1-2 keys will no longer be pressed). Usually, this happens if something falls on the laptop keyboard, or you accidentally hit the device (for example, this could be on the road when moving the device).

In some cases, when the contacts on the keyboard board are damaged (or the button is "clamped"), the keyboard may not respond to pressing other keys and behave unstably. By the way, if you have any key pressed, you can find out if you open any text editor: Word, notepad, etc.

Button "a" is stuck

By the way, if 1-2 keys do not work for you, then you can reassign to others and use the keyboard for some time (maybe this time will be long ?!).

8) What about the laptop battery?

And the last thing I would like to dwell on in this article. In general, this is quite rare, but still I met on one "no name" Chinese laptop: the keyboard on it stopped working if the battery was discharged and below a certain minimum of 7%, apparently a kind of software was working (I hope this software doesn't become popular?) .

This concludes my opus, for additions on the topic - a big merci in advance. Good luck!

Over time, everything breaks down sooner or later. This is especially true for computer hardware such as a keyboard. Often the keyboard stops working at all or some buttons do not work on it. What is the reason and how to fix this so as not to spend money on a new keyboard and not repeat mistakes? Let's consider further.

If some keys on the keyboard do not work

The keyboard and its one or more buttons do not work for the following reasons: driver damage, exposure to a virus or errors in settings, sticking, loose contacts and dirt. Sometimes water is caused by the lack of work of some keys, but often in this case the entire keyboard does not work.

What should be done in the above cases? There are a number of simple things to do:

1. Check if the connector of the wire of the device that connects it to the computer has fallen out; if it does, insert it back and restart the PC;
2. See if Num Lock (on a laptop) or F-lock (on a stationary computer) has been turned on - it must be off;
3. Update device drivers and scan the entire system for viruses. If viruses are found, remove them or reinstall the system;
4. Clean the buttons from dirt and sticky spots by taking the device apart.

Attention! In cases where the functional buttons on top and all other programs do not work, you should reinstall the system.

Also, some buttons do not work because the pc system is in safe mode. This means that the drivers are looking for the problem and the virus. When they finish their work, you should remove the safe mode and the buttons will work again. If the buttons do not work after these steps, it is recommended that you restart the computer system or reinstall Windows.

Reasons for keyboard malfunction

Incorrect operation of computer hardware is due to mechanical and software reasons. A mechanical cause is a broad concept, which includes breakdowns in the form of a cable break, moisture, excessive dirt, port integrity problems, problems with loose contacts, mechanical damage to the cable, etc. The software reason is software failures with incorrect BIOS settings, viruses, malfunctioning drivers, etc. In any case, the device needs repair and elimination of problems to continue working. To do this, you can contact the service center or try to solve the difficulties that arise on your own.

Dirt and liquid

Dirt with spilled liquid on the keyboard is the most common reason why buttons become malfunctioning. Often people are typing on a computer and drinking tea, coffee and other drinks. As a rule, close-standing drinks are spilled on the weak spot of computer equipment - the keyboard. As a result, it breaks down.

Mechanical damage by dirt or liquid can be easily identified by specialists and repaired. Anyone can also do this. There are five simple steps to follow: visually inspect the degree of damage to the device, remove the keys, clean, dry and reassemble. In 90% of cases, the keyboard starts displaying typed characters. If it does not work, there is only one way out - to buy a new one.

Loop damage

Loop damage is a more serious breakdown problem, with which they go to specialists. A flat cable is a wire that is located inside the keyboard and connects printed circuit boards and all additional electronic elements together. Wires have a large list of varieties and features of soldering due to the unusual arrangement of contacts. Therefore, the elimination of the breakdown of the loop is carried out in service centers.

Breakage occurs due to constant use of the device, rough handling and sticky keys. A frayed and broken train is replaced. To do this, take a copper wire suitable for the cross-section, clean the varnish layer and remove the wire. A new one is put in place of it. It is fixed with conductive glue and technical varnish. The recovery process takes about an hour. The main thing is to handle contacts well with improvised means.

Software reasons

A broken keyboard for software reasons is due to a software failure, a damaged driver, a virus on the computer, incorrect operation of drivers or the entire system. It also often fails due to the PC being in safe mode and the inconsistent build order at system startup.

How to troubleshoot

All arising problems can be eliminated by yourself or with the help of IT specialists. You can fix things on your own, for example, a software failure, viruses and driver malfunctions. A crashed or malfunctioning driver can be removed by restarting the computer or reinstalling the system. Viruses can be cleaned by running a licensed anti-virus system. If it does not help, then, as in the first case, you will need to reinstall the system.

What buttons stop working most often

Most often, the buttons used during virtual or downloaded games on the PC become faulty. As a rule, these are space, enter, tab, shift, numbers and F series buttons, arrows (down, up), letters, print screen, windows button. The most problematic is repairing the space bar. This is the longest button and has a metal bracket attached to the slots in each key support. The staple must be placed in the slot without pressing, since in case of deformation, it will not be possible to replace the key. Thus, this is a complex process that not every repairman undertakes.

As for the rest of the buttons, there are no problems with them: they can be simply replaced in case of breakdown with others, and also repaired.

In general, the keyboard breaks for a variety of reasons: mechanical or software. To avoid mechanical breakdowns, you should treat buttons and technology as carefully as possible. To avoid repetition of software errors, it is worth remembering a number of the tips listed above.
