The keyboard on the computer does not work. What to do if the buttons on the keyboard do not work


You may encounter the fact that the USB keyboard does not work at boot in different situations: this often happens when reinstalling the system or when a menu appears with a choice safe mode and other Windows boot options.

As a rule, this situation does not occur with a keyboard connected via the PS/2 port (and if it does occur, the problem should be looked for in the keyboard itself, the wire or the motherboard connector), but it may well occur on a laptop, since the built-in keyboard may also have USB interface.

Before continuing reading, check if everything is ok with the connection: is it in place? USB cable or wireless keyboard receiver, whether someone touched it. Even better, take it out and plug it in again, not in USB 3.0 (blue), but in USB 2.0 (Best in one of the ports on the back of the system unit. By the way, sometimes there is a special USB port with keyboard and mouse icon).

Is USB keyboard support enabled in BIOS?

Most often, to solve the problem, it is enough to go into the computer’s BIOS and enable the initialization of the USB keyboard (set USB Keyboard Support or Legacy USB Support to Enabled) when you turn on the computer. If this option is disabled for you, you may not notice it for a long time (because Windows itself “connects” the keyboard at boot and everything works for you), until you need to use it at boot operating system.

It is possible that you cannot enter the BIOS, especially if you have new computer with UEFI, Windows 8 or 8.1 and fast boot enabled. In this case, you can get into the settings (Change computer settings - Update and recovery - Recovery - Special options downloads, then to additional parameters select entry into UEFI settings). And after that, see what can be changed to make everything work.

On some motherboards, setting up support USB devices input on boot is a little more sophisticated: for example, in my UEFI settings There are three options - disabled initialization during ultra-fast boot, partial initialization and full initialization (at the same time fast loading must be disabled). And the wireless keyboard works at boot only in the latest version.

I hope the article was able to help you. And if not, describe in detail exactly how your problem arose and I will try to come up with something else and give advice in the comments.

Probably, each of us has encountered a similar situation: you turned on the computer, are trying to enter text on the keyboard or switch from one window to another, but the keys do not respond to pressing, and the device itself does not show any signs of life. What causes this behavior of the device? Why doesn't the keyboard on my computer or laptop work? And how to fix it? Let's consider what the reasons may be.

This is actually extremely awkward compared to others as it requires an excess of finger movement. Another standard is Dvorak. In addition, there are two other standards created for those who only need to enter one hand. Now check out some keyboards that might make you spend hours admiring the store window.

They usually have additional features compared to regular keyboards. You'll notice in the photo that there's also a mouse on the back of the touchpad-style peripheral. Anyone looking for practicality will want to have it. The keyboard below looks strange, but it makes the eyes of many gamers and graphics players sparkle because their keys are fully customizable not only in the function of the keys, but also in the position they occupy. You can literally put the keys wherever you want and assign them any function.

Mechanical damage

The simplest explanation is mechanical damage keyboards. Perhaps you recently spilled coffee or sweet tea on it, accidentally dropped it, pulled the wire, etc., and then conveniently forgot about it. In this case, all you have to do is disassemble the device and try to fix it yourself, or contact a service center. The second option is preferable, especially when it comes to a laptop keyboard. If you cannot bring the keyboard back to life, you will have to purchase a new input device.

Do your friends watch what you type and call you a “photographer”? It has both wired and wireless options and is available in Brazil. But it doesn't stop there, as the keys can be customized to display symbols for tools, commands, programs, or even images you've taken. Maybe in Portuguese we could have a keyboard that would better suit our needs and cause less pain in the hands of those who use the equipment for long hours on end?

Why hasn't a single keyboard manufacturer in Brazil proposed changing the standard to make life easier for users until today? With such great success in software interfaces to make it easier for the user because the keyboard is stopped in time?

Lost contact

Sometimes keyboard problems are caused by the device not being properly connected to the computer. Check whether the plug fits tightly into the socket on the system unit and whether the fragile parts of the connector are bent. If necessary, carefully straighten them with tweezers and try connecting the keyboard again.

If you use a wireless keyboard, it's worth checking to see if its battery is dead. Very often the problem disappears without a trace as soon as the power source is replaced.

Feel free to give your answers and explain your theories using the system feedback. If your keyboard is no longer working, there are a few things you can check to resolve the issue. Depending on the situation, you can try one of the following options: first you must define two important factors in this troubleshooting solution.

Your keyboard no longer works

The problem occurred while typing, or you noticed it immediately after starting your computer. Apart from an extreme situation such as spilling water on the keyboard, the answer to this question is important in identifying the problem. If you notice that your keyboard has stopped working after downloading or, check your connection to your keyboard and make sure it is locked properly. You can reboot again.

No corresponding driver

Why does the keyboard on the computer not work if the contact is not broken and the device itself is not damaged?

Perhaps the system simply cannot find the driver for the device. In this case, you need to update your computer software.

You can do this manually by visiting the website of your keyboard manufacturer.

What keyboard are you using?

Disable desktop computer and check if it doesn't work. Also check the batteries, it may be time to change them. Wireless receivers have a signal scan button, press the button to transmit the signal and the light should start flashing. Once this happens, find the key on your keyboard to receive the signal sent by the receiver and flow with each other.

In some ways, these keyboards are more reliable because there are no drivers to install from the operating system. If it stops working while using the operating system, in most cases the problem is not caused by the keyboard. Check if your mouse is moving slowly? Do the same for each application that is not responding. You can also try this for any type of keyboard.

  • Be patient and wait until the operating system finishes.
  • On the Application tab, select all and click End Task.
  • A confirmation window will appear asking you to stop it.
  • Click "End Task" again and wait for it to complete.
To determine the status of your keyboard, you can follow the last step.

Manual driver update

  • go to the official website of the manufacturer;
  • find the appropriate section, select your device model;
  • download the archive and unpack it. Sometimes the driver has its own automatic installer, in which case you will just need to click “Run file”;
  • if there is no automatic program, launch “Device Manager”;
  • select “Update drivers”, in the dialog that opens, select manual search, enter the path to the folder in which you unpacked the archive;
  • After installation, reboot the computer.

There is another way to update drivers. It is often recommended on thematic forums when a participant does not know why the keyboard does not work on a Windows 7 computer or other OS. You won't have to look for manufacturers' websites, but you will need to install additional programs to update drivers. For example, Driver Genius Professional or Driver Checker. These utilities are paid, but if you wish, you can find a replacement for them among free software (DriverMax Free, etc.).

If your keyboard no longer works, but you have a good second known keyboard with the same connection type, replace the correct keyboard with the incorrect one and see if it works. You can also try connecting the incorrect keyboard to another computer and determine if the keyboard is broken.

Troubleshooting Wireless Keyboards

If some keys on your keyboard work but not all, follow the steps below as appropriate for your situation. The eject button mechanism starts after a short delay to avoid accidental use. Press and hold until the eject icon appears on the screen.

Viruses attacked

Sometimes input devices are blocked by malware. If you don’t know why the keyboard on a laptop or computer, and along with it the touchpad and mouse, don’t work, then more likely, exactly at viral infection systems. What to do in this case?

and how can I fix it? Forgot your computer password? Don't worry - in our article you will find information on how to restore it.

Check your system with an antivirus as soon as possible. If the antivirus did not detect a potential threat or is simply disabled, use additional utilities. The Dr.Web CureIt! program is very effective in such situations. You can download this anti-virus utility on the official website of the Dr.Web laboratory. The program is free for treating home computers. The most important advantage of the utility is its high reliability: the program will work even if a virus tries to turn off the computer during the scanning process and block it.

Common problems with keyboard customization software

You may have configured a setting that changes the behavior of the keys. If the "Speak selected text when you press a key" option is activated, deactivate it or click "Change" to select a different key. If it is activated, you must hold the keys longer than usual for the action. In the Accessibility area, click Mouse and Trackpad. Make sure "Enable Mouse Keys" is turned off. If it is activated, pressing digital buttons moves the pointer, not the number. In the Keyboard panel, select Input Methods. Make sure the correct keyboard type is selected.

Problems with keyboard functionality such as calculator, sound or brightness settings

  • In the Accessibility area, click Speech on the Left.
  • Make sure the "Enable slow keys" option is disabled.
To get the latest version, click.

You can also recommend the development of Kaspersky studio, AVZ. Like Dr.Web CureIt!, the program is free. Updated regularly. It has several settings options, which allows you to most effectively identify not only viruses and spyware, but also possible system vulnerabilities. Quickly eliminates “computer infection” and gives many useful recommendations.

Identify your keyboard in this list or search in the search bar. Once you have identified your keyboard, tap or click on it to go to the download page. During installation, you may need to restart your computer one or more times. If you log in as a member of a guest group during the installation process, an error may occur.

Some computer manufacturers come with pre-installed keyboard customization software tailored to the keyboard that came with your computer.

  • Unplug your keyboard, then plug it back in.
  • If you are using a wireless keyboard, check your wireless connection.
If your device is supported, try the following.

The keyboard is simply not connected in the BIOS

Finally, the last reason for the “lifelessness” of the device is the lack of connection in the BIOS. This case is typical for netbooks and laptops, i.e. devices with a built-in keyboard. How to fix the situation?

Very simple. Turn off the computer, then turn it on again. Before the operating system starts loading, we load the BIOS. Usually to do this you need to click Delete button, But there may be other options. Sometimes the BIOS is activated by pressing the F2 or F8 keys (depending on the computer manufacturer). The hint at the bottom of the screen (if there is one) can help you determine which button to press.

Try it following tips. Some key commands require installation specific program such as email program, web browser, media player, exchange program instant messages or graphics editing program. Keys quick access may not work as expected if you press the modifier key at the same time. If correct program is not installed, you can still use the key by reassigning it.

If your computer has two connected wireless receiver, and you press one key on wireless keyboard, double characters may appear on the screen. Some keys are designed to repeat when pressed and held. The following buttons can be repeated: previous, next, previous track, next track, volume, volume, zoom, zoom.

Then we find a tab in the BIOS that lists all input/output devices. Select the item called “USB Controller” and set the mode to “Enabled”. Go to the “USB Keyboard Setup” item and repeat the operation, setting the mode to “Enabled”. Then we confirm saving the changes and exit the BIOS. Reboot and test the keyboard.

Where are the standard function keys?

These keys are located on the top row of the keyboard. On some keyboard models they are tactile.

What to do if the computer keyboard and mouse do not work?

Why doesn't the keyboard and mouse work on my laptop? - This is another, fairly common malfunction, which happens quite often in the event of an unexpected failure in a south bridge laptop.

Often south bridge burns out in such a way that absolutely everything works on the computer except these above-mentioned devices.

But sometimes it happens that the laptop stops turning on altogether, or stops responding to the power button, precisely when the same south bridge in it burns out.

➤ This is cool: You still don’t know - it’s simple.

Probably, each of us has encountered a similar situation: you turned on the computer, are trying to enter text on the keyboard or switch from one window to another, but the keys do not respond to pressing...

A computer keyboard is one of the main information input devices. At the same time, if problems arise in its operation, users immediately wonder why the keyboard on the computer does not work. As a rule, in order for the keyboard to start working, it is enough to connect it to system unit into a special PS/2 connector or USB port. But it often happens that after connection, the keyboard buttons do not respond to pressing and the lights do not light up. Therefore, let's figure out what to do if the keyboard stops working and how to solve the problem yourself.

We all know that in order to connect a keyboard to a computer, you just need to plug the plug into a special connector. In this case, the device will automatically be detected in the system and the appropriate drivers will be installed. The user only needs to wait a little. But there are times when, after turning on the computer, the keyboard shows no signs of life. There may be two reasons why the keyboard on a computer does not work.

  1. Mechanical damage to the device.
  • Cable damage. Check the integrity of the keyboard cable, it may be damaged;
  • PS/2 plug is broken. Very often in my practice I encountered situations where the pins in the keyboard plug were bent or broken off. In order to check this moment, pull out the purple plug and inspect the inside. If you see bent contacts, try to carefully straighten them and connect them back to the system unit;
  • Problem with PS/2 connector on . It is also quite common for the connector used to connect the keyboard and mouse to fail. Solution - installing a keyboard c USB interface;

Important! Be sure to perform all steps for connecting a keyboard with a PS/2 interface when the computer is turned off. This will allow you to avoid damage to the keyboard or port on the motherboard.

  • The keyboard board or microcontroller is faulty. IN in this case, replacing the keyboard with a new one will help, since repairs will not be practical.
  1. Software problem. Software failures when installing and connecting a keyboard are quite rare and are not always associated with operating system problems. Perhaps a failure occurred in the BIOS and the keyboard was disabled by software.

These are the main reasons why the keyboard on a computer does not work. Let's now take a closer look at how to solve problems with different types keyboards

Why doesn't my PS/2 keyboard work?

As I already described above, there are many reasons why the keyboard on a computer connected via the PS/2 interface does not work. If no mechanical damage is observed, then it is possible that the problem is software. Let's do it the following actions to resume keyboard operation.


As a rule, when software glitch, the ps/2 keyboard refuses to work if the i8042prt.sys and kbdclass.sys drivers are installed incorrectly.

Why doesn't the USB keyboard work on my computer?

Keyboards with a USB interface have long begun to replace keyboards with a PS/2 interface. USB keyboards are not so capricious and can work with the port USB versions 2.0 and USB 3.0. Therefore, it makes no difference which port you connect the keyboard to. It often happens that USB keyboard support is disabled in the BIOS. We definitely check this by following these steps:


After restarting the computer, the problem of why the keyboard on the computer does not work should be resolved. Some users have problems accessing the BIOS on USB keyboard. If this problem appeared in your case, then you should find a keyboard with a PS/2 connector, go into the BIOS from it and make the settings. After that, restart the computer and connect the USB keyboard.

Brief summary.

As you can see, today we figured out the reasons why the keyboard on the computer does not work, and also found ways to troubleshoot the problem. I always advise you to check the most basic things yourself. Since it often happens that the problem, for example, is that the user accidentally pulled out the keyboard plug with his foot, the wire was damaged, or the connector was broken. In such cases, you yourself will be able to diagnose the problems and easily find solutions. If the described methods did not help you bring your keyboard back to life, then I recommend replacing it with a new one. Fortunately, their prices are affordable and will be affordable for any user.

Failure of any of the computer peripheral elements means difficulty or complete cessation of operation of the entire set. If the keyboard does not work, then working with the computer becomes impossible, since the ability to enter data disappears. Usage 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 need to work right now and there is no time to run to the store for a new device. Often the problem can be solved on the spot without resorting to drastic methods.

Why the 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’s more difficult if the device shows no signs of life at all. The first action that needs to be performed is to determine possible reason malfunctions. To do this, you need to carefully inspect the device, the connecting wire, check the connection and decide further actions. Then you need to connect the problematic keyboard to another computer. It also wouldn’t hurt to connect a known-good keyboard to your computer and make sure there are no problems with the software or the operation of the connection ports. To put it simply, you need to figure out whether the keyboard is not working, or the problems lie in the computer.

Physical breakdown

Majority similar problems have quite noticeable outlines - a broken wire, mechanical damage, etc. Based on the nature of the detected flaw, one can make an approximate conclusion about the fate of the device, although damage to the case does not actually necessarily mean full output keyboards are out of order. The situation is more complicated when the keyboard does not work and has no visible signs of damage. If the problem persists when connecting to another computer, you should 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 keeping a mug of tea, coffee or other drinks next to the keyboard has damaged many devices

Software problems

If the keyboard works normally when connected to another computer, then the reason most likely lies in the software. You may need to install or update the device driver. First of all, you need to check the status of the keyboard in Device Manager. In Windows 7, for this you need right click mouse click on “computer” in the “Start” menu. In Windows 10, you can open it by typing “device manager” in the taskbar search box. If in the “keyboard” item there is a name problematic device without additional icons (usually a yellow triangle with exclamation point), which means the system sees it and does not find any problems.

Other reasons

Those who like to snack while working on the computer often spill various liquids on it. The habit of keeping a mug of tea, coffee or other drinks next to the keyboard has damaged many devices, but apparently it will not be eradicated soon. Usually, traces of spilled liquid remain on the surface, even if they are erased in time. Signs of such a malfunction are the lack of normal response to some buttons, sticking individual buttons, random keyboard commands. Often she starts endlessly typing one letter or executing a command.

For wireless samples common problem are batteries. 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 can be overcome in most cases. The course of action depends on the specifics of the problems that have arisen and is selected in accordance with their scale. Let's consider a possible algorithm of actions in this or that case.

Repairing or replacing the keyboard and connecting cable

Mechanical failures of the device can only be restored if small volumes destruction. A body fracture or similar major malfunctions leave no chance of success. The most successful actions may be to clean the device from any liquid that has penetrated inside (sweet tea, coffee) or replace the connecting wire.

To clean, you will need to disassemble the device. The keyboard is disconnected from the computer. All buttons are carefully removed, rubber transmitters are removed, and stains from dried drinks are wiped off with a soft brush and alcohol. After cleaning is completed, the keyboard is reassembled in the reverse order. Special attention it is necessary to pay attention to the installation of large buttons, which are not simply inserted into the corresponding sockets, but are fixed with metal guides.

Video: Repairing the connecting cable

If you don’t have ready-made soldered plugs at hand, the easiest way is to purchase new keyboard and do not waste time searching for the necessary parts or elements.

Repairs can only be carried out with skills and knowledge of the design. All actions taken at random positive results do not provide. If the essence of the breakdown is unclear, then the best thing to do is simply replace the keyboard with a new, working one.

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

Typically, drivers for major peripheral devices are included with the Windows system.

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 to “Enabled”. Then you need to find the “USB Keyboard Support” tab (it may also be called “ USB Legacy Support") and also set to "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, you can use a PC/2-USB adapter. In this case, most problems are solved automatically, but the functionality of the adapter must be checked.

Setting up the keyboard itself

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

  1. The speed (frequency) of repeating a symbol when a key is pressed.
  2. Delay before replay starts. The parameter determines the time it takes for the next character to appear when a key is pressed.
  3. The frequency at which the cursor flickers on the screen.
  4. Default input language.
  5. Keys for switching layouts.
  6. Additional language support

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

The keyboard is usually not configured, since the usual parameters are initially set by default. However, due to some user actions or system failures, the settings may change, so if any problems occur, it is recommended to install them in the necessary order.

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

One of the reasons for device failure may be a virus that entered the computer from the Internet or from an infected external storage device. If signs of unstable operation or complete failure appear, it is necessary to start full check 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 “Scan” button; for most antivirus programs it is located on home page and clearly visible. You can also download and run the Dr.Web CureIt! or Kaspersky Virus Removal Tool. This free programs, effectively detecting threats that may be missed by installed antivirus software.

Upon completion of scanning and removal of detected threats, the computer reboots

After scanning and removal of detected threats, the computer restarts and the device’s functionality is checked.

Checking the functionality of the keyboard itself

You need to be sure that the keyboard works. To do this, you should connect it to another computer and check its functionality. If the problem persists, the cause of the problem lies in the device itself. If she starts working in normal mode, then a hardware or software problem has arisen in the computer. This check option should be one of the first to be used, although another computer is not always available. The ability to localize a problem allows you to significantly speed up its solution.

Other

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

Problems with the keyboard can also arise for other reasons. For example, if you connect a PS/2 device to a switched-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 when the computer is turned on, but with old PS/2 this extraction option is not allowed. Necessary in a normal way turn off the computer and only then disconnect the keyboard and connect another one. In addition, they often include a PS/2 plug and a mouse socket located nearby.

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 a new device is not so high as to waste time on a failed keyboard with unpredictable results. Therefore, after making sure that the cause of the failure lies not in the computer hardware or software, but in the keyboard itself, you should decide whether it is worth repairing it, or whether it is easier to buy a new one. Independent actions Usually done due to lack of time or when there is nothing left to lose, trying will not ruin anything. You can send the keyboard in for repair only if it is expensive; the cost of repair is not comparable to the price of a new device. In other cases, the most reliable solution is to purchase a new keyboard.

It happens that sometimes the computer keyboard does not work after turning it on. At the same time, all other devices can work, but the keyboard does not respond to key presses and no LEDs on it light up. Let's figure out why the keyboard doesn't work and what to do in this situation.

Incorrectly connected

Most often, this problem occurs after a keyboard has been connected or reconnected to the computer, for example, after disassembling the computer. In this case, check whether the keyboard cable is connected to the system unit, and also whether it is fully inserted into the correct connector. If you have a laptop, you may need to take it apart again and check if you have connected the keyboard.

Problem with the system

In some cases, the computer may simply not detect the keyboard.

In this case, you should not ask why the computer keyboard does not work, but try to solve the problem. First, restart your computer. If this does not solve the problem, go to the control panel and right-click on “System”. Go to Properties and select the Hardware tab. In Device Manager, click on the keyboard and remove it, then close this window. Select the Hardware Installation tab and install your keyboard. This usually helps solve the problem.

Connect via BIOS

It happens that you cannot connect the keyboard by any means, especially when it comes to the question of why the laptop keyboard does not work. In this case, you need to connect it through the BIOS.

Turn off your computer and turn it on again. Before loading the operating system, load the BIOS. This is usually done using the Del key, but there may be another option. Follow the prompt at the bottom of the screen to understand which key to press.

Next, consider what tabs are in the BIOS, since they may be different in different situations, depending on the manufacturer. Your task is to find the tab with I/O devices and in the “USB Controller” item change the setting to Enabled.

After this, you can exit the BIOS by confirming saving the changes. Wait for the computer to turn on and check your keyboard.

In the case of old motherboards It is possible that the BIOS does not support USB keyboards. In this case, the BIOS needs to be reinstalled, but it is better to entrust this task to a professional.

If none of the methods help you solve the problem, try connecting a different keyboard to your computer. Perhaps the problem is with the computer and not with her.
