The wireless keyboard on the computer does not work, what should I do? Software or driver failure

Instructions

The main reasons for such a malfunction lie in a 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. The operating system may localize and resolve 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 the mode manual search 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 feature This is a 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 keyboard failure may also be the absence BIOS connections. 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.

Often PC users encounter a problem when it crashes and does not work. wireless keyboard. There are many reasons why this happens, ranging from simple and banal to hardware failure. In today's material, we will talk in detail about all the most common faults of wireless keyboards, and also consider ways to troubleshoot problems.

Low battery

The first and most commonplace wireless keyboard is a dead battery. It's no secret that all wireless peripherals run on batteries and, of course, need to be charged from time to time. If you don’t do this, then one day the device won’t work.

So, if suddenly the keyboard does not function, then first of all you should check the charge level, because it may be the culprit of the problem. If everything is fine with the batteries, then you should move on to the next point.

Wireless connection problem

Another very common reason why a wireless keyboard does not work is a malfunction wireless connection. Wireless peripherals connect to the computer via a Bluetooth adapter, but it’s not enough to just plug its connector into the system unit; you also need to make the connection itself, through the pairing button.

But it also happens that established connection between the keyboard and the computer is lost or broken, for example due to incorrect shutdown PC. To resume operation of the wireless keyboard, it will be enough to re-pair via the corresponding button on the peripheral itself. It's simple!

Driver failure

Next reason Why the wireless keyboard does not work is a driver failure. This is also a fairly common phenomenon, which, unfortunately, occurs at the most unexpected moment, and, alas, cannot be prevented.

There are actually many reasons why drivers can fail; even the same power surge and an unexpected reboot of the computer can contribute, but that’s not about that now.

You can try to fix the problem with drivers in two ways - simple reinstallation or complete removal and a clean install.

In the first case, you just need to reinstall the drivers and restart the computer. In the second case, you will have to perform several additional manipulations.

First, go to "Device Manager". This can be done easily - just click right click mouse on the "Start" icon and select the appropriate item from the menu that appears.

Next, in the “Device Manager” we find the “Keyboards” tab and expand it. There should be a keyboard in the tab that opens, and that’s what you need to remove. To do this, right-click on it and select “Delete device” in the context menu.

Now, after these simple manipulations, you need to restart the computer and perform a clean installation of the drivers on the keyboard.

Signal problems

Another common problem why a wireless keyboard doesn't work is an unstable Bluetooth signal. You need to carefully check how well the module is installed in the USB port, and whether there are any foreign objects, which can jam the signal.

“Jamming items,” as a rule, include Wi-Fi routers, modems, radios, phones with an enabled Wi-Fi module or 3G/4G connection, activated module Bluetooth on phones wireless speakers and stuff like that.

Bluetooth module

The next reason why a wireless keyboard stops working is the Bluetooth module. It often happens that wireless module is accidentally removed from the computer or becomes loose, causing power to be cut off. It also happens that users accidentally or mistakenly disable a module in the operating system, which also disrupts its operation.

IN in this case The problem can be fixed very simply - just reconnect the module to the computer or activate its operation in the system.

But we should not forget that there are cases when the Bluetooth module completely fails and, alas, nothing can be done to help. But before you write off wireless transmitter, it should be checked for functionality on another computer - you never know. If it is not detected there, then you can go to the store for a new module.

Liquid ingress

Prev last reason Why the wireless keyboard on the computer does not work is due to liquid getting into the periphery. No clarification is required in this case, since everything is clear to everyone. Many people experience spilling tea, coffee, juice or just water on the keyboard, after which it either begins to work poorly or stops working altogether.

What can be done in such a situation? Well, first, you need to disassemble the wet keyboard and leave it for about a day so that it is completely dry. After this, if something sweet was spilled, be sure to carefully wipe all the elements, especially the circuit with the paths for the buttons, with an alcohol wipe. Once this is done, you can assemble the keyboard and try to connect it.

In most cases, everything works out well, and the periphery continues to function, but there may also be sad consequences in the form of failure of individual buttons or blocks, as well as complete failure of the entire keyboard.

Keyboard failure

And finally, the last reason. Why doesn't my wireless keyboard work, but my mouse does? It's a good question, but the answer to it will be sad for many. If none of the above methods helps solve the problem, and the peripherals refuse to work, then there is only one thing left - a broken keyboard.

In this case, the only solution that will help resolve the problem is to purchase new peripherals.

Of course, this is not the most common situation, but it still happens from time to time: the user turns on the computer, the boot is successful, and then it is discovered that the keyboard does not work. Moreover, it is completely unclear why this happened and how to get out of the situation now. Maybe you need to call a specialist or worse than that, format the disk and reinstall Windows? Don’t rush to panic, most likely you will cope and on our own.

Why it might not work computer keyboard? Why doesn't my wireless keyboard work? Why doesn't my USB keyboard work? Why doesn't the additional keyboard on the right (numeric) work? Why don't half the keys on my keyboard work?

Why might my computer keyboard not work?

The simplest and most common cause of keyboard failure, which can be eliminated in just a couple of seconds, is that the PS/2 plug accidentally fell out of the socket. Perhaps this kind of accident has four legs, a tail and a cheerful disposition.

The keyboard cord may have been pulled out while cleaning. In a word, the first thing to do is check the position of the plug in the socket, remove it and insert it back, and then, if the situation remains unchanged, restart the computer.

However, we should not exclude other cases – for example, a virus attack. You can run an anti-virus scan using mouse clicks. If it doesn’t find anything, it means the problem is more serious - either the keyboard connection port has burned out, or the keyboard itself has malfunctioned.

Although extremely rare, this still happens sometimes. You can check this assumption by connecting another, known-good keyboard. If this does not help, there is no choice, the next step is testing using professional equipment.

Why doesn't my wireless keyboard work?

Needless to say, a wireless keyboard is a convenient invention, but it has one drawback common to all wireless gadgets: it needs to be charged. If you forgot to charge your keyboard on time, it is not surprising that it refuses to work.

A new wireless keyboard that has not yet worked requires installation of its own driver. Usually the computer itself finds the required driver in memory, or for the device in included driver disk.
But sometimes in automatic mode the driver does not install, and then you have to search and install manually.

The same is done if the driver was deleted for some reason - “lost”, as experts say.

Why doesn't my USB keyboard work?

A USB keyboard differs from a regular keyboard only in the connection connector - it’s easy to guess that this is a USB connector. Therefore, the verification algorithm is approximately the same as for a keyboard with a PS/2 connector:

Checking the reliability of contact;

Anti-virus scan;

Connecting a working keyboard;

Testing using special equipment.

However, another option is possible - changing the BIOS settings. To enter the BIOS, you need to start booting and press the appropriate key, most often Del or F6, and find the tab that displays I/O devices.

Opposite the “USB Controller” item, set the status to “Enabled”, then go to the “USB Keyboard Setup” item and also set “Enabled” opposite it, i.e. included. After that, exit the BIOS, remembering to confirm the save changes made.

Why doesn't the additional keyboard on the right (numeric) work?

The numeric keypad is located to the right of the main one. It is not available on all types of keyboards and is practically not used by most users.
If you still have it, and suddenly need to turn it on, you just need to press the “Num Lock” button, which is usually located in top row numeric keypad.

Why don't half the keys on my keyboard work?

The failure of half the keys is most typical for the so-called multimedia keyboard, on which multimedia adjustments (sound, brightness, color rendering, etc.) are implemented in the form of button controls.

This media part sometimes crashes after booting due to the media key switching service being disabled. The cause may be a voltage surge in the power supply network, hardware failure and other computer problems.

This problem can be fixed very easily. Need to:

Go to the Start menu;

Select “Control Panel”;

Select “System and Security”;

Select “Administration”;

Select “Services”;

Select “Access to HID devices” and right-click;

Select “Properties” from the drop-down menu;

Select the “General” tab and click on the “Run” button.
To eliminate the possibility of service outages in the future, follow these steps:

Select the “Recovery” tab;

Find the line “Subsequent failures”;

Click the “Restart service” button;

Click “Apply” and “OK”.

After this, if there is a failure, the media buttons will start automatically.

How to connect a wireless keyboard?

After purchasing any gadget, you need to connect it, but it is not always clear from the instructions included with it how to do this. In this article we will tell you about connecting a wireless keyboard to your computer.

Installing the keyboard is easy, provided that in addition to it you have:

• USB adapter;
• driver disk;
• free USB port on your computer;
• batteries (usually AA batteries).

If everything is there, you can proceed with the actual installation:

1. Insert the disc into the DVD-ROM and wait for the installation program to autorun. If this does not happen, then click the “My Computer” icon and open the disk being used.
2. We find the installation file on it (with the extension .exe) and, following the prompts that appear, install the program.
3. Insert the adapter into the USB port.
4. Insert batteries if they are not already installed.

If everything is done correctly, a message indicating that the device has been detected will appear on the monitor. The computer itself will find and activate drivers for the wireless keyboard. Once the message “the device is ready for use” appears, you can use it.

How to enable a wireless keyboard?

Sometimes you need to additionally enable the keyboard. To do this, move the lever from the “Off” to “On” position. It is most often located on the bottom or top side panel of the device.

What should I do if my wireless keyboard doesn't work?

It happens that the keyboard stops or never starts working. Here's what you can do in this case:

1. Check batteries. It happens that they are not installed correctly or they are discharged.
2. Press down the USB adapter. He could simply move away and stop receiving the signal. In some cases, it’s worth trying to move it to another connector.
3. Make sure Bluetooth is turned on.
4. Remove all metal objects, including cell phones.

If the keyboard does not work, you should contact a specialist.

A wireless keyboard can be used not only to work on a computer, but also to control a TV, system Smart home"or an alarm.

2 reasons and troubleshooting of the keyboard

The statement that equipment you take care of lasts longer and breaks less often is also true for computer peripherals. Especially for mechanical devices input. You should regularly disassemble (remove the buttons) and clean the keyboard.

This, at a minimum, will avoid the inconvenience associated with incorrect typing and sticky keys. It is better to clean with a cotton swab moistened with alcohol. To avoid corrosion of plastic and other materials used in manufacturing, acetone-based solvents cannot be used. Before cleaning, record the order of the keys in a photo or other way.

Prevention is necessary, but does not provide iron-clad guarantees, and for one reason or another, a breakdown may occur.

Check the connection. Make sure that the keyboard is properly connected to the computer, first try reconnecting it and restarting the PC. Disconnect it for 10-15 seconds, and then try to connect again. Use a different USB connector.

When connecting through a hub or KVM switch, the reason for the failure may be in this intermediary. If you are using a PS/2-USB adapter, check whether your device supports it.

Make sure there is no mechanical damage. Turn off your computer. Disconnect the keyboard from the socket and check the cable for any kinks. If it is connected via a PS/2 port, you need to carefully inspect it and if you notice that the contacts are bent, carefully fix them with tweezers.

Try using the device on another computer. Among other things, the PS/2 port on the motherboard may be faulty and you should try connecting the keyboard to another PC. When the connection is made via USB, located on the front panel of the system unit, there is a possibility that the contact of the port with the motherboard is broken.

The worst case scenario is that the USB controller fails, but this can be easily checked using a flash drive.

Keyboard malfunction due to software glitch

The software is already integrated into the Windows operating system distributions required for most devices used. But if your new one is not recalled multimedia keyboard, then the reason for the inoperability lies, rather, in the lack of drivers or a malfunction in its operation.

First of all, check whether the system correctly detects the device. To do this, right-click on the “Start” icon. In the dialog box that opens, select the “Control Panel” line.

If there is a problem, in the window that appears next to the line “keyboard” there will be exclamation mark. However, even if it is not there, it is worth trying to reinstall the driver.

In addition, it makes sense to right-click on the “keyboard” and update the hardware configuration, or run automatic update drivers. The OS will automatically begin searching the Internet and installing the necessary software.

Use programs that make the search process automated and do not require active intervention. Free: Driver Pack Solution, Driver Booster, Device Doctor or paid ones: Driver Detective, Driver Genius, Driver Reviver are also useful when you cannot find the software yourself.

Manual update. By selecting manual update, we see a new dialog box that prompts you to enter an address to search for update files. Specify the location of the driver, click next. First, make sure that the required driver is available on your hard drive. To do this, you should visit the manufacturer’s website and download the software corresponding to the marking of your device.

The delivery set includes a disc. Insert the disc into the drive, autorun will work, complete the installation necessary programs according to the prompts that appear. If “autorun” did not work, then open the distribution folder and find executable file. Run it double click. The file has the extension .exe; to see this, enable the display of extensions in your computer settings. To do this, we follow the path: “Control panel”? “Design and personalization”? “Display hidden files and folders."

In the window that opens, uncheck the “Hide extensions for known file types” checkbox. "Apply."

Also " software reason» can be connected to a USB chipset controller motherboard. In this case, you need to update the drivers for it.

The operating system is infected with a virus. We scan the OS with an antivirus installed on the computer or select an online virus scan on the appropriate service.

The keyboard must be connected in the BIOS. This case is typical for a situation where it is necessary to connect additional keyboard to the laptop.

We reboot the OS, press the F2 button or the Delete button, other options are possible (depending on the manufacturer), at the moment of loading, a hint appears at the bottom of the screen.

In the BIOS we find a tab that displays a list of input/output devices (see How to enter the BIOS). Find the USB Controller item and activate it by selecting Enabled. Next, in the USB Keyboard Support line, select the same value – Enabled. Changes are saved by pressing the F10 button.

When the keyboard doesn't work

If the keyboard is faulty, work on the PC is suspended. If there is a login password, the OS will not be able to boot, since there is no way to enter it.

The periphery of the working kit does not work

When you turn on your PC and discover that the keyboard doesn’t work, your annoyance is replaced by surprise: it worked yesterday.

Possible reasons:

If the device does not respond to key presses when you turn on the working PC, the very first thing to do is check the connection of the peripherals to system unit. If the cord is pulled out of the PC connector, the reason for the inoperability is simply simple. To make the keyboard work, just plug the plug tightly into the connector and reboot the computer. Peripherals can be connected through another connector of a similar port or, using an adapter, to other ports. It will work if the PS /2 or USB port is burned out.
It's a funny situation when peripherals are connected to the wrong PS /2 port. Coloring the plug and connector intended for peripherals - a keyboard or mouse - in the same color eliminates confusion. The purple keyboard plug must be plugged into the purple PS /2 port.

Keystrokes can be blocked computer viruses. You can verify that the keyboard is connected by pressing the keys Caps Lock or Num Lock: an indication should appear indicating that they are turned on. After treating your PC with an antivirus, your computer should be in perfect order.

Other reasons

For another reason, you need to go to Device Manager and look in the equipment to see if there are devices that are not determined by the system(the equipment will not be detected if the driver is not installed or has crashed). It will not be possible to view the status of equipment without working keys when the input is password protected. We'll have to look boot disk with a minimal OS and a set of utilities that allow you to view the status of the system and equipment.

Often a false problem occurs when entering digital input from the field on the right side of the device. Entry is only possible when the Num Lock key located above the numbers is pressed. If there is no backlight indication indicating the state of the key, entering numbers is blocked. · Due to dirt; The keys stick and don't work due to dirt. In case of inoperability due to lack of contact due to crumbs, dust, moisture from spilled coffee, the periphery is disassembled, cleaned of debris, the contacts are wiped with alcohol, and the slipped seals are returned to their place. The work is labor-intensive; those who have disassembled the device themselves know that disassembling it is easier than assembling it.

· Due to an outdated driver;

The equipment may not work due to an outdated or broken driver. This cause of the problem will be resolved by updating the driver. To do this, you will need a software disc included with the purchased peripherals or files downloaded from the Internet to install the driver. To update the driver, you need to click the Start button, go to Control Panel, select Hardware, expand the list of devices in Hardware Manager. Become the mouse on the keyboard, right-click to open the menu, select Properties. In the Driver tab of the window that appears, select Update, then follow all the suggested actions. For correct operation updated driver the computer needs to be rebooted.

If users complain about the inability to play with keys, they should go to the game settings and select the desired key action. The default key control is changed.

The mechanism itself may be faulty (everything breaks down at some point), or the cord may have been broken or bitten by an animal. You can verify the malfunction by connecting the equipment to another PC.

New peripherals don't work

Manufacturers produce peripherals with keys, pressing which is equivalent to typing commands. It's hard to resist replacing your old keyboard with a better one. When a new keyboard does not work when connected, the search for the cause must begin with the connection.

If the peripheral you are replacing was running on a PS/2 port, the lack of communication with the new device connected via the USB port may be due to the port being closed for use. You can configure it to connect a keyboard by going to the BIOS menu and opening (Enabled) USB port support Keyboard Support. Also responsible for connection USB controller, in SETUP you need to correctly configure USB Controller by setting it to Enable.

Installing drivers for a new keyboard

In order for the new equipment to work, you need to install drivers. It can be done in different ways:

Manual driver installation

– Go to the System from the Control Panel, open its Properties window, select working with Equipment, action – Installation; – in the Installation Wizard window that opens, agree to further work by clicking the Next button. You will be prompted to select the location of the distribution. The installer will extract necessary information from the specified folder, will set additional questions, will notify you of the completed connection with the message “Installation of new devices is complete.” The new device will work correctly after restarting the PC.

Even experienced users may experience some confusion if, when turning on the PC and booting Windows For some reason the keyboard stopped working. A variant of the problem is when only separate buttons. Less experienced Windows users and computers in general, people immediately think about repairing or buying a new device. But maybe the problem is in the operating system - has the keyboard stopped working? If you have another one at hand, then checking the functionality of the first one will not be difficult. But what to do when this is not possible? We will try to figure out why the keyboard on the computer does not work and how to solve it this problem.

In total, there are five main situations, the occurrence of which may result in the device not responding and the reason why the keyboard stopped working when turned on:

• immediate breakdown;
• PS/2 / USB port malfunction;
• lack of normal contact between the keyboard connector and PS/2 / USB;
• problems with the wireless keyboard;
• blocking the device in Windows virus or malware.

A banal breakdown is the most common reason that your keyboard is not working. As for the malfunction of the port, although it is rare, it can burn out for some reason. Despite the fact that users rarely encounter this situation, it certainly cannot be ruled out. It is also possible that the keyboard is like with USB input, and PS/2 - it doesn’t work because you connected the connector to the port incorrectly. Another option for its inoperability lies in bent contacts.

It's easier with wireless ones. One of the most common reasons why such a device stops working is a dead battery or lack of Windows required drivers. 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 actions, the implementation of which will help solve the problem:

• you need to make sure that the keyboard is correctly connected to the system unit;
  it is important to understand whether the wire is damaged;
• you need to turn off the PC, and then disconnect and reconnect the device;
• understand whether the “clave” has stopped;
• PS/2 / USB port status is tested using another device.

If the user is not careful, the keyboard connector may be damaged due to mechanical stress. Therefore, you should check whether one or more pins on the PS/2 plug are bent. Remember that you need to check the purple connector if we are talking about PS/2; USB is a small rectangular connector (however, USB port for such devices in lately is used less frequently, so it is unlikely that you own a USB keyboard). If such a problem does occur, then you can try to straighten the legs. To do this you should use fine instruments, for example, a knitting needle or small tweezers.

For a wireless keyboard, it is important to ensure that the batteries have sufficient charge to operate. normal operation. In fact, everything described above is quite common and typical problems. But there are a number of other situations.

Why some buttons may not work

Multimedia keyboards require separate drivers. Without them, compatibility with the Windows operating system is impossible. A natural question arises: where did the drivers go? The main reasons for their absence are damage or removal after reinstalling the Windows operating system.

Usually, similar devices They install the drivers themselves, in particular on Windows 7 and 10. Here, Microsoft developers have done everything possible to ensure that the system is fully automated. But these OSes may require additional installation.

It happens that when several buttons are pressed at once, the keyboard stops functioning. The problem may be caused by some external interference. If the only button does not work, then it is easier to purchase a new device.

How to enable the keyboard in BIOS

This problem can be solved quite simply. Many computers block the keyboard connector or USB keyboard from working. To do this, you just need to activate the desired option when you turn on the machine. Enter the BIOS (by clicking the appropriate buttons during boot, instructions can easily be found on the Internet) and follow the following path: Onboard Services – USB Keyboard Support USB keyboards), and then change "Disabled" to "Enabled". Then save the settings.

Simultaneous keyboard and mouse dysfunction and/or gaming problems

If this happens, then such a problem should not be considered serious either. There is a maximum probability that the reason lies in the motherboard, namely in the USB or PS/2 ports. You can try connecting the device to other connectors, and then turn on the computer again. If no changes occur, then it is best to contact a specialist. If you advanced user, then you probably know that there is a testing 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 problem is internal settings"gameplay". To solve the problem, it is enough to assign necessary commands in the Options menu. Each game allows you to customize it, that is, you can make sure that only keys that are convenient for you respond to game commands.

Any USB keyboard can suddenly outgrow its functionality - even a regular budget one, or one with an advanced design, backlighting, and a bunch of other stuff. additional buttons. USB keyboards are slightly, but still more vulnerable than keyboards connected via the PS/2 port. The list of possible causes of problems with the PS/2 keyboard is small: as a rule, problems arise either with the keyboard itself, or with the wire, or with the motherboard connector. The range of possible causes of problems with USB keyboards is slightly wider, respectively, due to the USB interface. We will discuss the possible causes of a non-working USB keyboard and ways to resolve the situation below.

1. Pulled wire

If the USB keyboard was working successfully, and then at one point stopped responding to input, you should first check whether the wire has been pulled out of the USB port on the computer. Even if the wire is in place, you can temporarily remove it from the USB port and insert it again after a couple of seconds.

2. Another USB port

If previous method did not give successful results, you need to reconnect the keyboard to another USB port. This will either reveal that one of or eliminate one possible cause of the problem. After a motherboard failure due to a power surge, one or more USB ports may stop working, while others remain operational. If the keyboard does not work with any of the USB ports, you need to check the functionality of the USB ports themselves by connecting any other device to them - a flash drive, mobile device, printer, etc. If all the USB ports on the computer turn out to be inoperative, the problem will then need to be resolved with them.

Keyboard connected to USB 3.0 (port with output blue), may not work during the process Windows installations until the drivers are installed on the motherboard. In this case, the keyboard must be reconnected to USB 2.0 (port with white).

3. Reinstalling the driver

If reconnecting to another USB port does not produce results, you need to check whether the keyboard works in the BIOS environment. The fact that you successfully enter the BIOS and use the navigation keys to move through its sections will mean that the problem arose at the Windows OS level. In this case, you can try to reinstall the keyboard drivers. You can do this in the manager Windows devices. You can get into it in Windows 7 by calling the “Start” menu and selecting “Control Panel”.

On Windows 8.1 and 10 systems, the path is shorter: Device Manager is available via a direct link in the context menu on the Start button.

Directly in the device manager window, open the “Keyboards” section, and in the “HID Keyboard” item, call context menu and remove the driver.

We confirm the decision.

Reboot the computer.

After rebooting, the keyboard driver will be installed automatically.

For individual models Manufacturers of USB keyboards may provide their own drivers included with such keyboards. This point needs to be clarified, and if this is the case, then the driver must be installed manually by downloading it from the manufacturer’s website or by finding installation disk included with the keyboard.

4. Enable USB controller keyboard support in BIOS

A malfunction of the motherboard (as a consequence of the same power surge) may cause the USB keyboard support controller to turn off in BIOS settings. Not often, however, it also happens that the USB keyboard support controller at the BIOS level is initially disabled. This nuance will make itself felt only when it becomes necessary to operate the computer in pre-boot mode. Until this moment Windows system will use a USB keyboard own funds. Of course, in such cases you cannot do without a PS/2 keyboard, and if one is not stored anywhere just in case, you will need to borrow it from someone for a while. Alternative option- usage USB adapter- PS/2.

What should you do once you enter the BIOS? In the BIOS settings, you need to find the USB keyboard support controller option. These are usually the words “Keyboard Support” or “Legacy USB Support”. The UEFI BIOS may simply have the name "USB Support". Having found it, you need to check that the value opposite is not “Disabled” (turned off), but “Enabled” (enabled). The value “Enabled” should also be in the “USB Controller” parameter. For example, in AMI BIOS version 17.9 USB controllers are configured in the “Integrated Peripherals” section.

5. Faulty keyboard

And finally, the simplest test to check the functionality of the USB keyboard itself is to connect it to another computer device.

Have a great day!
