Even experienced users may experience some confusion if the keyboard stops working for some reason after turning on the PC and loading Windows. A variant of the problem is when only individual buttons do not work. Less experienced Windows and computer users in general immediately think about repairing or buying a new device. But maybe the problem is in the operating system - did the keyboard stop working? If you have another at hand, then it will not be difficult to check the performance of the first one. But what to do when there is no such possibility? We will try to figure out why the keyboard on the computer does not work and how you can solve this problem.
In total, there are five main situations, the occurrence of which can lead to the lack of recoil of the device and the reason why the keyboard stopped working when turned on:
- direct breakdown;
- malfunction of the PS / 2 / USB port;
- lack of normal contact between the keyboard connector and PS / 2 / USB;
- problems with the wireless keyboard;
- blocking a device in Windows with a virus or malware.
Banal breakdown is the most common reason that your keyboard does not work. As for the port malfunction, although it is rare, it can burn out for some reason. Despite the fact that users rarely encounter such a situation, it definitely should not be ruled out. It is also possible that the keyboard — both USB and PS / 2 — is not working because you incorrectly plugged the connector into the port. Another variant of its inoperability lies in the bent contacts.
It's easier with wireless. One of the most common reasons why this has stopped working is a dead battery or the lack of necessary drivers in Windows. With viruses blocking the keyboard, everything is much more complicated, despite the fact that such a situation is extremely unlikely.
What actions need to be taken
There are several simple steps that can be taken to solve the problem:
- you need to make sure that the keyboard is correctly connected to the system unit;
it is important to understand if the wire is damaged; - you need to turn off the PC, and then disconnect and reconnect the device;
- to understand whether the "claudia" has stopped;
- The PS / 2 / USB port status is being tested with another device.
If the user is not careful, the keyboard connector may be damaged due to mechanical stress. Therefore, check to see if one or more of the pins in the PS / 2 plug are bent. Remember to check the purple connector for PS / 2; USB is a small rectangular connector (however, the USB port for such devices has been used less often lately, so it is unlikely that you own a USB keyboard). If such a nuisance does happen, then you can try to straighten the legs. To do this, use thin tools such as a knitting needle or small tweezers.
In the case of a wireless keyboard, it is important to ensure that the batteries have sufficient power for normal operation. In fact, everything described above is quite common and typical problems. But there are a number of other situations.
Why individual buttons may not work
Multimedia keyboards require separate drivers. Without them, compatibility with the Windows operating system is impossible. A natural question arises: in fact, where did the drivers go? The main reasons for their absence are damage or deletion after reinstalling the Windows operating system.
Usually, such devices install the drivers themselves, in particular, on Windows 7 and 10. Here Microsoft developers did everything possible to make the system fully automated. However, these OSs may require additional installation.
It so happens that when several buttons are clamped at once, the keyboard stops functioning. Some external noise may be causing the problem. If the only button does not work, then it is easier to purchase a new device.
How to enable keyboard in BIOS
This problem can be solved quite simply. Many computers block the operation of the keyboard or USB keyboard connector. To do this, you just need to activate the desired option when turning on the machine. Enter the BIOS (by pressing the appropriate buttons at boot time, the instruction is easily searched on the Web) and go to the following path: Onboard Services - USB Keyboard Support, and then change "Disabled" to "Enabled". Then save the settings.
Simultaneous keyboard and mouse dysfunction and / or problems in games
If this happens, then such a problem should also not be considered serious. There is a maximum chance that the reason lies in the motherboard, namely in the USB or PS / 2 ports. You can try to connect the device to other connectors, and then turn on the computer again. If no changes have occurred, then it is best to consult a specialist. If you are an experienced user, then you probably know that there is a test option through the BIOS settings. If this does not help, then another computer is needed for the final check.
If the device and / or individual buttons do not function in a certain game, then, most likely, the matter is precisely in the internal settings of the "gameplay". To solve the problem, just assign the required commands in the "Options" menu. Each game allows you to customize it "for yourself", that is, you can make it so that only the keys that are convenient for you will respond to game commands.

There are many reasons why your keyboard might not perform well or show any signs of life at all. First, you need to immediately determine the root cause of such a breakdown: software or hardware. In simple terms, either the keyboard itself is faulty, or the problem lies in the Windows settings.
So, in order ...
The keyboard works, but some keys do not work well (sticky, do not respond to pressing, etc.).
The reason is usually simple - the keyboard is dirty.
You need to disassemble the keyboard and clean it. It doesn't matter what kind of keyboard you have (usb, standard, wireless, built into a laptop). Turn the keyboard over, remove a few screws. Here you will see that there is a rubber pad under each button. Sometimes it happens that the pad breaks or "slides" from its place- as a result, the corresponding key does not work. Then you just put everything in its place.
The key buttons can be wiped clean with anything, any cleaning agent. But it is better not to touch the translucent film and everything else. By the way, so as not to get confused where which key should be, take a picture of your keyboard in advance. Of course, you can later find your keyboard model on the Internet and arrange the keys. But, nevertheless, it is much more convenient to take a photo of your keyboard. Some even number the keys with a pencil so they don't get confused later. After "cleaning", place the keys in their places, place the rubber pads (they can be placed in any order - they are all the same). The work is painstaking, but the result will be a great working keyboard.
Plug problem
If you have a classic keyboard (with a round purple plug), it sometimes happens that the small legs of the plug may bend.
In general, this type of connector is called PS / 2. Purple is for the keyboard, green is for the mouse. If you forcefully insert the plug, the legs may bend. Then you need to take tweezers (or small pliers) and straighten all the legs.
USB - keyboard
This is an ordinary keyboard, only it is connected not to the PS / 2 connector, but to the USB connector.
If such a keyboard does not work when connected, then the problem most likely lies in the BIOS settings (SETUP). When you start the computer, press Del (or F6, everyone has different keys).
And since you cannot use a mouse in the bios settings, a reasonable question appears: "How can I press Del at startup, and how will I configure bios if the keyboard does not work for me ???!" The problem is solved simply - go to your neighbor and ask him for a keyboard for 5 minutes :)
Wireless keyboard
I'll ask you a stupid question: "Have you charged your keyboard?"
Surprisingly, usually the battery just runs out and people forget to recharge it.
It also happens that Windows simply cannot install drivers for your wireless keyboard. Then search for drivers on the Internet manually.
Drivers
It happens that some new installed program unknowingly corrupts the keyboard drivers. If you have Windows 7 installed, then driver problems should not bother you. The system itself installs and restores the drivers. Usually, you just need to restart your computer.
But there are times when the driver gets messed up or the new driver doesn't work well. In such cases, you can do two things. First, restore the system to the day when the keyboard worked fine. Secondly, you can go to the device manager and update the drivers, or view their properties by looking at the diagnostics.
Keys don't work in a particular program or game
You should find the settings for a program or game and look at the key assignments. In general, check out the settings. In games, as a rule, the keys can be reassigned. And in the programs, see the list of hot keys.
Some other tips
If the computer emits three long beeps (beeps, sounds) when you turn it on, this means that you inserted the keyboard incorrectly. Just pull out the plug and plug it in again.
If the keyboard does not work suddenly, first of all, check it on other computers. If you have only one computer (usually everyone has this), then go to your neighbor and check the keyboard on his computer.
Sometimes it happens that a (computer) mouse starts to work poorly - to jam and freeze. The mouse will continuously appear to be disconnected and connected (and the computer will beep to indicate that the device is connected). Due to the fact that the computer will constantly recheck the input devices connected to it, the keyboard will also begin to work poorly. Then just pull out the mouse and recheck the keyboard.
There are also times when the mouse and keyboard cannot work at the same time. This happens EXTREMELY rarely, but it can happen. In some unknown way, some mouse models are simply incompatible with some keyboard models (?!). I have personally encountered such a case only once. It is usually possible to trick the computer in this case. You need to find a mouse or keyboard in the registry and assign them different names. Sometimes it helps ... For the same reason, joysticks (gamepads) may sometimes not work in games. For example, a game only lets you use Microsoft gamepads, and the others just don't work. Then you need to find your gamepad in the registry and rename it to the name Microsoft.
If the keyboard does not work, and you still need to find something on the Internet (for example: drivers for the keyboard), then you can use the on-screen keyboard.
That's all. Ask questions - I will be happy to answer them.
Thank you for your attention!

Sometimes users are faced with 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 very beginning, do this:
1.Try pressing the Fn and Num Lock keys. It is possible that pressing one of them blocked some of the 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 quite 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.
Vacuum cleaner for keyboard
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 corrected 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 in 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 DriverPack Solution program. It allows you to scan your entire computer for the latest available drivers.
If the keyboard has incorrect (roughly "broken") or irrelevant drivers, you can easily remove them. Using this program looks like this:
- download the program (here is the link);
- install it and run;
- an automatic scan will take place, after which just click on the "Update All" button.
DriverPack Solution Window
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";
- then go to the "Service" section and click on the item "System Restore";
The item "System Restore" 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 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 the laptop.
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 latches of the keyboard plate
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, you just need to remove the loop and replace it 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 those 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 loops.
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 through all the controllers you see. You can't do anything on your own without special knowledge. Again, if you see obvious damage on the microcontroller, it is best to replace it.
Laptop with keyboard removed
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 it off with the same flat screwdriver. Start with the problem 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.
Use a tester to check the integrity of the tracks.
Part of the keyboard does not work on a laptop: what to do and how to fix it - a detailed guide
5 (100%) 2 vote [s]The keyboard is the main tool for entering information, without which it is impossible to work on a computer. Most often, in order for this device to work flawlessly, it is enough to simply connect it to the computer, and it will install all the necessary drivers automatically. This happens in most cases, but not always. There are situations when, when the keyboard is connected to the USB or PS / 2 connector, it is not detected on the computer and does not show any signs of operation - the indicators are off, and the buttons do not work. As part of this article, we offer instructions on what to do if the keyboard on your computer does not work.
We recommend reading:
Connecting a keyboard to a computer is as simple as possible - just insert its wire into the corresponding connector on the motherboard, and then the device will start working. There are wireless keyboards, the radio receiver from which is inserted into the USB-connector, after which the device works if the distance between the transmitter and the device is observed.
Due to the simplicity of the process of connecting a computer, we can conclude that there are only 2 reasons why the keyboard does not work on a computer:
- Mechanical. Problems may arise directly with the keyboard or the wire that connects it to the motherboard. A broken connector on the motherboard may also be the cause of the malfunction.
- Software. The keyboard drivers are installed automatically, but during the installation of any software failures may occur, and this situation is no exception. In addition, problems may not be observed at the operating system level, but in the BIOS, where the appropriate settings for the keyboard are disabled.
Depending on which connector the keyboard is connected to the computer, we offer different solutions to the problems that arise.
What to do if the keyboard does not work on the computer via the USB protocol
The most common interface for connecting a keyboard to a computer is USB. The speed of information transfer from a peripheral device to the computer is sufficient, both via the USB 2.0 protocol and via USB 3.0, so there is no difference in which connector to connect the keyboard.
If the USB keyboard does not work when you turn on your computer, do the following:
It is worth noting that users whose keyboard is connected to the motherboard via USB may have problems navigating to BIOS on the computer's boot screen if they are using an old version of the basic software. In this case, you need to find a keyboard with a PS / 2 connector or use the appropriate adapter.
What to do if the keyboard does not work on the computer via PS / 2 protocol
Keyboard makers are moving away from the PS / 2 connector in favor of USB. It is very difficult to find a keyboard with a PS / 2 connector on sale, but if you come across such peripherals and it does not work when Windows boots, the problem is most likely related to the drivers. To make the keyboard work, you need to do the following:
It should be noted that a similar problem with keyboards connected via PS / 2 protocol most often occurs due to an error during the installation of the i8042prt.sys or kbdclass.sys driver.
Why the keyboard doesn't work: main reasons, symptoms, remedies.
Symptoms of a keyboard malfunction
To fix the problem, you need to establish its cause, which means, figure out why the keyboard on the laptop does not work: due to mechanical stress or spilled liquid, after visiting questionable sites or installing new software. Or maybe malfunctions began to appear suddenly, without any reason .
Also should check individual buttons on the keyboard do not work or is it completely out of order, and if so, has it stopped working in the operating system or in the BIOS too.
Symptoms of a broken keyboard:
Spilled liquid
Water, tea, coffee, soup, alcohol got on the keyboard
If you spill any liquid on the keyboard, turn off immediately laptop: holding the power button for a few seconds or simply removing the battery. At the same time, try to hold it so that liquid does not seep under the keyboard, inside the computer. This can lead to malfunction of the motherboard and other components. 
After shutting down, blot the keyboard with a dry cloth and disconnect it from the laptop. This is done quite simply: it is enough to press with something thin on the latches located on top or on the sides of it Their location differs depending on the manufacturer and model of the laptop..
be careful: A thin ribbon cable connects the keyboard to the computer, be careful not to damage it with an awkward movement. Now you need to wipe the keyboard with an alcohol wipe and leave to dry. You can speed up this process with a hair dryer, but only with cold air.
When the keyboard and laptop are completely dry, put it back in and try turning it on. There is a chance that now everything will become as before, however, if any malfunctions appear, there is only one way out: replacement with a new one. If the laptop stops turning on at all or is unstable, feel free to take it to the workshop. An ordinary user cannot cope with such breakdowns on his own.
Some buttons on the keyboard do not work
Keys do not respond to keystrokes or are typing the wrong characters
If, for no apparent reason, any buttons on the keyboard do not work, while others continue to work, then you should check, first, if you have Num Lock turned off. If this is the problem, then the numbers on the right 
will not function on the keyboard, the computer will see arrows instead .
Find the "Num Lock" button to the left of them (in the upper right part of the keyboard) and press it. On some laptop models, you need to press one of the hot keys (F3, F11, etc.) together with the function (fn) key.
If other buttons stopped working, check if there is dust under them, which prevents them from pressing. In this case, you should either thoroughly blow through the keyboard with a special spray can, which you can buy in a store, or remove the keys by gently prying them with something thin (for example, a screwdriver) and wipe the keyboard by hand.
The whole keyboard is not working
No keyboard keys respond to keystrokes
If the keyboard on the laptop does not work at all for no apparent reason, try restarting it and entering the BIOS. If the keyboard works before Windows boots, then the problem is in the system, and you will not have to spend money on a replacement.
Most likely, a virus has wound up on your computer that has deleted or damaged the corresponding driver which was the reason why the keyboard doesn't work. Perform a full scan using your antivirus, and after finishing the treatment, update the keyboard driver manually by installing it from the disk that came with the laptop, 
or automatically: by letting the system download it from the Internet.
In the first case, you just need to insert the disc into the drive and follow the instructions of the installer. In the second - right-click on the "Computer" shortcut, select "Properties", in the window that opens in the upper left corner, click on the "Device Manager" item. Find the line "Keyboard" in the manager, open it and you will see the corresponding device. Click on it with the left mouse button twice, or right-click and select the "Properties" option. In the new window, open the Driver tab and click Update.
If this did not help (no virus was found 
or the system did not find a more suitable driver, and the keyboard still does not work), you should try to restore or reinstall Windows.
Even if the keyboard does not work in the BIOS on a laptop, the easiest way is to take it to the workshop, especially if you have never done computer repair yourself and have no idea how to do it. Not only can you damage your laptop even worse by acting at random, but also because not every store can find the exact keyboard your laptop needs. In our workshop, we will select the required device ourselves and install it correctly.
However, if together with the keyboard you have the touchpad does not work and USB inputs, then be prepared for the worst: this is a clear sign of a malfunctioning motherboard. Its repair or replacement requires much more time and money, and it certainly cannot be done without the help of professionals.
