What to do if the keyboard does not work. Incorrect installation of keyboard drivers. Why the keyboard on the computer does not work when turned on: problem solving

Sometimes it happens that after turning on the laptop, the user is faced with the fact that the keyboard does not respond to touch. Don’t worry – often there is no problem at all, and everything can be resolved very easily. The thing is that a failure may occur in the operating system, which leads to the fact that the keyboard is no longer perceived (this situation especially often occurs when the old laptop Windows 10 is installed).
Let's consider a few recommendations on how to turn on the PC if the keyboard on the laptop does not print? By the way, according to search engine statistics, this is a very pressing issue.

So, in order for the keyboard on a laptop to start working, in the vast majority of cases, it will be enough to simply restart the computer.

Bios

In this case, you will need to go into the BIOS (this should be done at the moment when the PC is just starting to boot). At this moment you will need to press the TAB key, and if that doesn’t help, then press F10 or DEL. In fact, if you were able to perform at least one of these actions, then everything will indicate that the failure is not mechanical and the cause must be sought in the software.
Exit the BIOS and reboot the system again. We evaluate the result.

Possible driver problems

It is possible that the problem of the laptop not recognizing the keyboard lies in the drivers. Solving the issue in in this case does not present any difficulties. It will be enough to look at the name of its model on the packaging of your laptop, visit the official website, download required driver and install it on your laptop.
In the event that installing the driver did not help you resolve the issue, then this will clearly indicate that the failure is purely mechanical in nature and will need to be corrected accordingly.

Mechanical damage

To be honest, all users love to drink coffee while sitting at a laptop or eat flour products that contain a lot of crumbs. They are precisely the reason why several keys or the entire keyboard does not work. In this case, you will have to disassemble the laptop, otherwise you won’t be able to get them out of there.

Before you start, you need to make sure that the device is not under warranty. Otherwise, you could simply take it to the store and they would already repair your laptop, otherwise you will have to do everything yourself. Or contact the service center.
Often the cause of laptop malfunction (and often fatal) is liquid getting on the laptop keyboard.


In this case, it will be necessary to urgently disconnect it from the power supply, turn it off using the start button, disassemble it and wipe it thoroughly. Then the laptop should dry out for 24 hours. By the way, it is much worse if the spilled liquid was sweet - in this case, you will need to wipe it with an alcohol wipe.
In addition, sometimes the cause may be a broken cable. In this case, you will definitely need to take it to a service center.

The problem when the keyboard on a computer or laptop does not work is not uncommon. This situation is faced by both beginners and experienced users who have been working at a computer for many years. Let's figure out how to find a solution to the problem when the keyboard stops working, the keys stick or does not respond to pressing.

What could be the reasons for the breakdown and their solutions?

I decided to write an article in the form of points so that you can go through them and find out why the keyboard does not work.

There is information on the blog when the keyboard on a laptop stopped working: “”.

1. Beginner users usually immediately rush into panic and forget about the most trivial things. The very first thing you need to check is whether the keyboard is connected to the system unit (directly to motherboard).

1. Disconnect the keyboard for a while (5-10 seconds) and connect it again.

1. If your keyboard suddenly stops working, try restarting your computer. Sometimes re Windows boot helps.

1. Nowadays it is very popular to use wireless keyboards and mice. If you have used wired keyboards before and at the moment If you have a wireless one, then I remind you that batteries are discharged, and from time to time they need to be recharged.

1. All modern keyboards are connected through a special connector called a USB port. If there is free USB port, then try connecting the keyboard to it. If all ports are busy, disconnect the printer or any other device to check the USB port for functionality by connecting a keyboard there.

1. If you have children at home, then it makes sense to check for extra items, in the connector or in the system unit(motherboard). I once witnessed a situation where there was paper or chewing gum in the USB port, and therefore the keyboard stopped working.

1. It is possible that the keyboard has already done its job. To check if it works for you, you can go to your neighbors and ask them to connect your keyboard to their computer. If the keyboard works, then there is something wrong with your computer. You may have a spare keyboard, then connect it to your computer.

1. If the keyboard only partially prints, you may be unable to type numbers that are on the right side of the keyboard. If so, then click the " Num Lock».

1. What should I do if the keyboard does not work, but you have already done all the methods described above? If you have an old-style keyboard called PS/2 (piss in half), then pay attention to the legs. They may be curved or one of the legs may be completely absent. These legs may bend when connecting the device in a hurry, but they do not bend on their own. If there is no leg, then you will have to change the keyboard; if it is curved, then you can correct it with improvised means, for example, a screwdriver or a knife.

For the future, you should know that the purple connector is designated as the keyboard, and the green connector is the mouse.

1. If there are food crumbs in the keyboard or you simply dropped it or hit it, then it makes sense to disassemble it. If you use the keyboard for a long time or if it gets hit, the rubber inside may slip off. When you disassemble the keyboard, you need to adjust and clean the rubber, if necessary.

Wipe the rubber with a dry cloth, and the keyboard itself can be wiped with a damp cloth.

When disassembling the keyboard, it is important for novice users not to forget where all the keys were. In order not to get confused about the location of the keys, you can find a photo on the Internet that will be identical to your keyboard. Also, when disassembling, you can put the keys on the table in the order they were or take a photo with your cell phone.

1. If the USB keyboard does not work, then you can look in the BIOS to see if it is disabled. But there is one caveat: to enter the BIOS we need a keyboard that will work on this computer. There is a way out. You need to take a PS/2 keyboard or a USB to PS/2 adapter. By connecting PS/2 you can now use the keyboard. Go into the BIOS and switch USB Keyboard Support to Enabled. We also make sure that the USB Controller is Enabled.

1. Another reason for the keyboard to fail is that the driver on the computer, which is responsible for the correct functioning of the keyboard, may have stopped working. In such a situation, there are a number of steps you can take to try to troubleshoot the problem yourself.

Firstly, you can do a system restore or roll it back to the date when the keyboard worked normally. Stretch your memory to remember the approximate date ;).

Secondly, try updating the keyboard driver. To do this, go to “Device Manager” and find our keyboard. Right-click and select "Update drivers..."

1. If when you purchased your keyboard it came with a driver disc, you need to install them. Before installation, remove old drivers.

When the keyboard does not work: you now know what to do and how to find out the reason. Just in case, go through all the points; perhaps you missed some of them.

Keys do not work in a program or game

Users who like to play games sometimes encounter a problem when some of the keys do not work.

If the keyboard works, but after entering a program or some game, some keys refuse to work. In this case, it would be appropriate to first look at the assignment of the keys. If you are not satisfied with how they are set, then look for their settings in the game itself. In some games you need to save all changes, so don't forget about it.

Usually all hotkeys in programs are the same, but there are exceptions. To change them, find the key settings in the program itself. Change the part of the hotkeys that you are not happy with to the ones you are familiar with.

If your keyboard doesn’t work, and you’ve tried everything I’ve said here, then you can buy the most ordinary keyboard, since their cost is not high.

Do you like to eat on your laptop? Then this video is for you:

It doesn’t matter what kind of laptop you have: asus, acer, hp, samsung, toshiba, dell or sony vaio the keyboard may suddenly become stubborn, or rather not work.

Why doesn't my laptop keyboard work? There are several reasons. The worst thing is if the bridge (controller) has fallen.

Then you need to take it to a workshop or you need to replace it entirely, and for your laptop model there may not be a keyboard.

However, don’t be too sad, you can buy a computer keyboard (costs from $15).

You can also use the virtual one - it’s inconvenient, but you can be patient. Now let's take it in order - let's put everything on the shelves.

The first reason why the keyboard suddenly does not work

If the buttons show no signs of life, the problem is most likely in the laptop’s motherboard - the microcircuit has burned out. What to do - a technician at home or a laptop to a service center.

If the touchpad and USB ports are functioning, you can dance - in most cases the matter is fixable.

It’s bad if the cable doesn’t contact (it’s wrung out, oxidized, etc., sometimes it requires replacement), but it’s fixable. At minimal knowledge electronics - you can try to fix it yourself.

I won’t describe how, look online for information about the keyboard cable with pictures and you’ll see everything with your own eyes, but we’ll move on to the following reasons.

The second reason why the keyboard on a laptop fails to work

Many people fiddle around when only part of the laptop buttons do not work, not suspecting that they themselves were the cause.

Laptops have some keys on the right side with numbers, in addition to letters.

This keyboard option is provided for those who work a lot with numbers. This makes it possible to introduce them much faster.

The third reason for keyboard failure

Virus. Yes, yes, it is precisely this that can damage the drivers responsible for the operation of the keyboard, and the laptop will not only begin to become dull, but also refuse to work.

However, drivers can fail for other reasons. This doesn’t matter, they need to be restored, for this you can use the usual one or by logging into .

Minor laptop keyboard problems

If you usually work for battery, if the battery is low, the keyboard may not work. What to do. Take out the battery - connect the network, insert the battery - charge it completely and continue to work as if nothing had happened.

• What to do if only the keys do not work, you can read more.

Sometimes you just need to clean your laptop keys. I’ll tell you how to do this using a funny example. I once killed a fly on the keyboard of my Asus laptop with a fly swatter, and as a result, 8 keys jumped out of their sockets - absolutely undamaged. I cleaned the keyboard and put the buttons back in their places.

Of course, you don’t do this, and if you need to clean the buttons, it’s best to use a special air canister. Then you won't have to remove the buttons - it costs about $10.

In conclusion, I would like to say or remind you that all components of the laptop, including the keyboard, are displayed in the device manager (you can look at their performance). Look, maybe you will find the reason there.

There are many reasons why your keyboard may not work well or may not show any signs of life at all. First, you need to immediately determine the root cause of such a breakdown: software or hardware. Speaking in simple language- 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 (stick, do not respond to pressure, 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 the laptop). Turn the keyboard over and unscrew a few screws. Here you will see that under each button there is a rubber pad. Sometimes it happens that the lining breaks or “slips” out of place.- as a result, the corresponding key does not work. Then you just put everything in its place.

The key buttons can be wiped with anything, any cleaning agent. But it’s better not to touch the translucent film and everything else. By the way, so as not to get confused later about where each key should be, take a photo of your keyboard in advance. Of course, you can then find your keyboard model on the Internet and arrange the keys. But, still, it is much more convenient to take a photo of your keyboard. Some even number the keys in pencil to avoid confusion later. After “cleaning”, arrange 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 perfectly working keyboard.

Plug problem

If you have a classic keyboard (with a round purple plug), then sometimes it happens that the small legs of the plug can bend.

In general, this type of connector is called PS/2. Purple is for the keyboard, green is for the mouse. If you forcefully try to 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 a regular keyboard, but 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 in bios settings If you can’t use a mouse, then a reasonable question arises: “How can I press Del at startup, and how will I configure the bios if my keyboard doesn’t work???!” The problem can be 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, the battery usually just runs out and people forget to recharge it.

And 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 keyboard drivers. If you have Windows 7 installed, then driver problems should not bother you. The system itself installs and restores drivers. Usually, you just need to restart your computer.

But there are times when the driver is damaged, or new driver doesn't work well. In such cases, you can proceed in two ways. First, restore the system to the day when the keyboard worked properly. 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 specific program or game

You should find the program or game settings and look at the key assignments. In general, study the settings. In games, as a rule, keys can be reassigned. And in programs, look at the list of hot keys.

Some other tips

If, when you turn on the computer, it makes three long beeps (beep, sound), this means that you have inserted the keyboard incorrectly. Simply pull out the plug and reinsert.

If the keyboard suddenly does not work, first of all, check it on other computers. If you only have one computer (usually everyone does), then go to your neighbor and check the keyboard on his computer.

Sometimes it happens that the mouse (computer) begins to work poorly - it jams and freezes. The mouse will constantly seem to be disconnecting and connecting (at the same time the computer will make beep about connecting the device). 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 cases when the mouse and keyboard cannot work at the same time. This happens EXTREMELY rarely, but it can happen. Somehow, some mouse models are simply incompatible with some keyboard models(?!). I personally encountered such a case only once. Usually you can fool the computer in this case. You need to find the mouse or keyboard in the registry and assign different names to them. Sometimes this helps... For the same reason, joysticks (gamepads) may sometimes not work in games. For example, the game allows you to use gamepads only from Microsoft, and the rest simply do not work. Then you need to find your gamepad in the registry and rename it to 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!

Instructions

The main reasons for this malfunction lie in hardware failure or software error. Checking the hardware version is very simple - check the plug on your keyboard and the connection connector. If everything is visually in order, replace the keyboard with a working one and reboot the computer. If you continue to be unable to use this device, you should check the version software malfunction.

First, try rebooting the machine. Maybe, operating system localizes and eliminates software glitch. Try reinstalling the keyboard. To do this, in the “System Properties” window of the “System” item “Control Panel”, find the “Hardware” tab. Click the "Device Manager" button. In the "Device Manager" window, select the "Keyboard" item and delete it, close the "Device Manager". Then enter the “Hardware Installation” item and run the “Setup Wizard”. Click Next and wait for the installer to detect the keyboard. The OS will indicate that the keyboard is detected and functioning by turning on indicator light Num Lock. If the program displays a message that the installation of new devices is complete and prompts you to reboot, then click the “No” button, since the keyboard is already functioning. Also click the “Finish” button in the “Found New Hardware Wizard” window and exit the “System Properties” menu.

One possible problem could be that the operating system does not detect required driver. To reinstall the driver, go to your keyboard manufacturer's website, select the desired model, download the archive and extract it. As a rule, such drivers are equipped with their own installation program, and then you should just run the file. If there is none, you will have to launch the “Device Manager”, select the “Update Driver” command and specify in manual search mode the path to the directory in which the unpacked driver is located. The computer must be restarted after installation.

Often, keyboard not working– consequence virus program, settled in your car. A characteristic sign of this is the failure of the mouse, as well as the touchpad. Check the system with antivirus program. Better not to rely on free utilities, promising instant success and healing of your computer. Use reputable and well-known antiviruses. The chances of success with such security are much higher.

Quite the real reason A keyboard failure may also be due to a lack of BIOS connection. This failure is especially common on machines with a built-in keyboard. Correcting the situation can be quite simple. As your computer boots, enable the BIOS. Find the tab with a list of input and output devices. Select USB Controller and turn on Enabled. Enable the same mode for the USB Keyboard Setup item. Exit the BIOS with confirmation to save the new settings. If none of the above helped you, contact the service center.
