Install drivers for the keyboard. The keyboard on the laptop does not work. How to find and install keyboard drivers from A4Tech

A4Tech is a well-known manufacturer of keyboards and other computer peripherals. Its devices are improved from time to time, and they also update the software that is needed to support the functionality of the device - the driver. In modern versions Windows update drivers for important system components (the keyboard is one of them) occurs in the background and practically does not interfere with the user.

However, this does not always happen and is due to the fact that the keyboard has not received required update drivers, various problems may occur. In this article we will look at how you can independently update your keyboard drivers from the manufacturer A4Tech.

How to find and install keyboard drivers from A4Tech

It is worth clarifying that for keyboards that have non-standard functionality and a set of keys, it is imperative to install drivers and additional software manually, since the system sometimes does not always correctly recognize this device. As for the usual standard keyboards, then usually the system itself detects everything correctly and installs the necessary software in the background.

Option 1: Through the official website of the manufacturer

First of all, when installing drivers, you need to go to the manufacturer’s official website and try to install them from this resource. For A4Tech products step by step instructions will look like this:

Go to the official software download page for A4Tech devices.
Some antivirus programs block the manufacturer's official page because they suspect that it may contain malware and/or other unwanted software. Fortunately, the official website is completely safe. If you have problems with your antivirus, simply disable it while performing the steps. Typically, modern antivirus programs rarely work on this site.
On the page you need to select the category to which your device belongs. This is done through a drop-down menu. Since we are looking for drivers for keyboards, pay attention to the sections “Wired Keyboards”, “Sets and Wireless Keyboards” and “Gaming Keyboards”. Select one of these sections that best suits your application. at the moment keyboards.
Now indicate the model of your keyboard in the special field. If you don’t know it, then look it up on the keyboard itself. It is usually written on the back. Select the desired model from the drop-down menu and click on the “Open” button.
Next, you will be redirected to a page on which a list of all software supported by the keyboard will be presented. Also here you can see information regarding the keyboard driver itself - weight, release date, operating system support and a brief description from the manufacturer.
Click on the "Download" button. As a result, an archive with installation file. Wait for the download to complete. After this, you will need to unzip the contents of this archive onto your computer. For your own convenience, it is better to do this in a separate folder.
Among the extracted files, find the element called Setup. It must have an executable file extension - EXE. Sometimes it happens that such a file has a different name and you will only have to look for it by extension.
Run the file. If the operating system asks you to confirm your actions, then additionally click on the “Run” button or give permission if administrator rights are requested.
The driver installer interface for the A4Tech keyboard will now open. Here you only need to read the information provided in the window and click on the “Next” button to continue the installation.
You will then need to specify the future location installed driver. By default it is set to local disk C. However, if you consider it necessary, you can select a different location for the installed drivers by using the “Browse” button.
Having decided on the installation location, click on the “Next” button.
At this stage, the program will ask you to specify a name for the folder in which the driver will be installed. Here it is recommended not to bother with this and leave all the default settings by simply clicking on “Next”.
The next window allows the user to check the previously entered information. If everything here is correct, then click on “Next”.
The installation process of the necessary software will begin. It usually doesn't take long, although a lot depends on your computer configuration. Wait for the program installation to complete.
At the end, a window will appear in which it will be written that the installation was completed successfully. Click "Done".
A keyboard icon should appear in the taskbar next to the time and date. If it is there, then everything went well. Click on it if you want to see the available settings.

This method is most recommended, as it involves installing the latest drivers directly from the device manufacturer’s website. The above instructions can be taken as a sample, since sometimes the installation process still differs between different users. This usually depends on the selected keyboard model, driver release date and other parameters.

Option 2: Third Party Software

This option does not always work perfectly, but it has a right to exist, since it implies faster and easy installation necessary for the correct operation of the software. However, it is not always done correctly - sometimes it is installed outdated version drivers or they are not installed at all. A significant advantage of this method is the fact that other drivers on the computer are also updated, for example, video card drivers.

Today on the Internet you can find many programs responsible for automatic update drivers. As an example, consider the implementation using DriverPack Solution s. That's enough simple utility, which has an interface in Russian and is distributed free of charge.

Go to the utility download page. There click on the download button.
It will be downloaded to your computer executable file programs. Launch it. It is worth noting that DriverPack Solution does not require installation and can be launched immediately after downloading.

After opening, the utility will scan operating system for outdated drivers available for download. It will take no more than a minute.

Based on the scan results, you will be prompted to install the detected drivers. However, you should not rush, since additional software, for example, a browser, may be installed on your computer along with them. Installing these programs will not harm the system, but the user does not always need them.
To disable their installation, go to “Expert Mode”. To do this, use the button of the same name at the bottom of the program window.

Next, pay attention to left menu. Here you need to open the “Soft” tab, which is marked with an icon in the form of 4 squares.
There, uncheck those programs that you do not intend to install.

After this, return back to the main utility window using the button in the form of a wrench. Here, by the way, you can select the drivers that will be installed. Some of them can be disabled.
Click on the “Install All” button.

Wait while the utility prepares a system restore point. This is a standard procedure that takes no more than a couple of minutes.
After the restore point has been created, the process of installing drivers and selected programs will begin (if you have not unchecked them). It takes a little time.

Once finished, it is best to restart your computer and check if the keyboard is working properly. Ideally, a keyboard icon should appear on the taskbar.

DriverPack Solution allows you to save a lot of time searching and installing the necessary drivers. However, he does not always cope with the task perfectly. Sometimes it happens that the required driver is not installed or is installed incorrectly.

Option 3: Search by hardware ID

Each device connected to a computer is assigned a unique ID (sometimes there may be several IDs for one device). Using it, you can get comprehensive information about this device on specialized resources, as well as find the latest drivers for it (again on the same resources).

We have already looked at how to search for drivers by hardware ID number: How to find a driver by hardware ID

In short, you will have to do the following:

Option 4: Device Manager

This option is suitable in cases where you need to install only the most basic drivers for the keyboard. If you are using a model with some specific capabilities, it is better to use the methods described above.

Let's move on to implementing this method:

Launch Device Manager. How to do this was written above. If you have another Windows version, then it can be launched through the “Control Panel”.
Expand the “Keyboards” branch again.
Now click right click mouse over the desired element and select the “Update drivers” option from the context menu.
The system will offer options for searching and installing drivers. It is recommended to select the option " Automatic search updated drivers." The fact is that on your computer you most likely do not have necessary files, so this is the only option left.
Wait while the system searches and installs drivers.
Restart your computer when finished.

Despite the fact that users often experience problems with their keyboards, the process of installing drivers is not difficult if you follow the instructions provided. If you have any difficulties and/or questions regarding the article, please leave comments. We will try to respond as quickly as possible.

Each of us connects an input device to our PC. But what if it doesn't work correctly? You need to download drivers for the Windows 10 keyboard. This is one of the main computer control devices. Thanks to it we can enter characters, write messages, search necessary information, play and so on.

All ways to download Keyboard driver

So, you connected the input device, restarted the PC, however, it does not work correctly. Let's look at methods to download a keyboard driver for Windows 10.

Automatic installation

The new operating system itself detects connected devices and selects software. All you need to do is connect the keyboard.

device Manager

If you have connected an input device to your computer, but nothing happens, then:

Right-click on the start menu.
Will open context menu. Select "Device Manager".

In the window that appears, find the unidentified device.
Right-click on it and select "Update driver".
Click on "Automatically search for updated drivers".

The system itself will find, download and install keyboard drivers for Windows 10 on your laptop or computer.

Driver.ru

There is a huge database of software on the Internet for various devices driver.ru. All you need to know is your keyboard model:

Downloading a keyboard driver for a computer on Windows 10 is all that remains for you in a situation where the keyboard does not work. It is important to distinguish between the situation that the keyboard does not work from the very beginning or it breaks after a long time of use. If you just installed the OS and the keyboard does not work, then the problem is probably in the drivers. If you've been using your computer for years and the keyboard suddenly stops working, then it's most likely due to a physical breakdown. Be that as it may, you can download drivers for the keyboard and at least try to solve the problem using them.

Are there drivers for the keyboard?

Many people believe that the keyboard does not need drivers. But this is completely wrong. The keyboard is a component like any other. Just because you've never installed keyboard drivers before doesn't mean you don't need to install them now. Usually, the system itself loads the necessary drivers. So before, you didn't have to download them yourself. But if after installing the new OS the keyboard does not work, then download the drivers and the problem will go away. The problem with the keyboard is usually solved after installing the drivers, but you need to know a number of facts:

Doesn't exist universal driver for keyboard;
The driver is needed for a laptop keyboard and a regular keyboard;
The installed driver may crash;

If the problem persists after installing the driver, then there is a chance that the problem was not with the drivers. But if you didn’t physically break the keyboard, then try to revive it using drivers. This option is unlikely if the keyboard stops working after a long time. Downloading the driver is a matter of minutes. If this solves your problem, then you can save a lot of money because you won't have to buy a new one.

You need to download drivers for the keyboard not only on your computer, but also on your laptop. And if you use wireless keyboard on a Windows 10 tablet, then you need to install drivers for it too. Since there is no universal Keyboard driver, we are posting the program - . It will allow you to install any driver, including the keyboard driver. The program will cope even if the keyboard is wireless, that is, if you need a driver for a Bluetooth keyboard.

Desktop computers have two key input devices: the mouse and the keyboard. Therefore, when any failure occurs and the keyboard/mouse stops working, the computer actually turns into useless hardware. We have already looked at this before, and in this article we will look at why the keyboard on desktop PCs may fail to work.

Checking the wires

The keyboard is connected to the system unit via two types of connectors - outdated PS/2 or modern USB.

Initially, check the integrity of the wire itself; if there are no defects, proceed to inspect the connectors. In the case of PS/2, the plug contacts are often bent; in the worst case, they can be completely broken off when the user inserts the plug with all his might, but it does not fit into the connector due to incorrect placement. If you have a newer keyboard connected to your computer via a USB connector, then simply switch the keyboard to another USB port, since the contacts in them can also fail. ATTENTION: it is recommended to disconnect and reconnect the keyboard when the computer is turned off, or after connecting it, restart it. For example, in the case of a PS/2 connector, there is a 90% chance that the keyboard will not work without restarting the computer.

Updating the driver

If you have a special gaming keyboard or similar multimedia keyboard with a bunch of additional functional buttons, then drivers should be included with them. They can also be downloaded from the official websites of manufacturers. In the case of simple keyboards, you can update the drivers using the Windows OS itself. Due to a software glitch, the keyboard driver may crash, so you need to install it again.

Open menu Start - Control Panel - Device Manager. In the list of devices, find Keyboards, right-click on the selected one and click Update drivers. For Windows to update the driver itself, the computer must be connected to the Internet. If for some reason the update fails, you will have to independently find a driver for your keyboard model on the Internet, download and install it.

As a rule, these two reasons lead to the keyboard not working on desktop PCs in 99% of cases - broken connector contacts and lost drivers. The remaining 1% is when the keyboard itself fails, as well as very exotic cases. For example, viruses that block the keyboard; lost or incorrectly configured BIOS settings.

Sometimes after Windows starts, the keyboard remains “unresponsive” (does not respond to key presses). In this case, the keyboard indicator lights do not light up.

There are two main causes of the malfunction: hardware (the keyboard or the port to which it is connected has failed) or software (failure to load the driver).

If the keyboard fails, it needs to be replaced with a working one (or repaired).

What to do in case of a software failure?

1. You can try to restart your PC. After a reboot (if the keyboard is working properly), the operating system will “deal” with the keyboard drivers, and the incident, as a rule, should be resolved.

2. You can use the keyboard without restarting the PC (in this case, the mouse should function normally!).

To do this:

Click Start -> Settings -> Control Panel -> System;

In the System Properties window, open the Hardware -> Device Manager tab;

In the Device Manager window, the keyboard will be marked with a yellow circle with a black exclamation point inside -> select it with the mouse;

Select menu Action -> Delete;

In the Device Removal Confirmation window, authorize the removal of the keyboard by clicking OK;

Close the Device Manager window;

On the Hardware tab of the System Properties window, click the Add Hardware button;

In the Add Hardware Wizard window, click Next;

After a short search for the equipment, the keyboard will be “found” (the Num Lock indicator will turn on);

If the Change system settings window appears with the message “Installation of new devices is complete. You must restart your computer to complete the software installation. The new settings will only take effect after the system is rebooted. Should I reboot now? Yes/No", click No, since the keyboard already works without rebooting;

In the Add Hardware Wizard window, click Finish;

Close the System Properties window;

You can work with your keyboard.

Notes

1. The problem described in the article is observed on a PC with a PS/2 keyboard.

2. The problem is usually caused by a failure to load the i8042 port driver (\WINDOWS\system32\drivers\i8042prt.sys). Less often, the keyboard class driver (\WINDOWS\system32\drivers\kbdclass.sys) fails.

3. If this malfunction occurs in the system event log (see Can the log Windows events become fascinating reading?) events of two types are recorded, for example:

Warning (Event Source: i8042prt; Event ID: 20; Description: Keyboard LED status cannot be set);

Error (Event Source: Service Control Manager; Event ID: 7026; Description: Failed to load the system reboot or startup driver(s): i8042prt).

In this article we have to understand an important question: why does the keyboard not print? This phenomenon is not as rare as we would like. But you shouldn't be afraid of him. Problems are resolved without any problems. And only in some situations it is necessary to make a lot of effort to improve the functioning of the computer component. But for what reasons might the keyboard refuse to work? And what to do in this or that case?

Connector damage

The first case does not occur very often, but it does occur. Especially on older computers. For laptops, this situation is relevant only when we are talking about a separately connected keyboard.

What are we talking about? Why doesn't the keyboard print? The problem may lie in the equipment connector. It sometimes breaks or gets damaged. In this situation, the keyboard cannot be connected. If you are using an older model (PS/2 socket), it is advisable to change the hardware to USB. Or connect the device to another connector. You can also try to repair the nests. But this technique will not provide a long-term guarantee of the device’s operation.

Drivers

Why doesn't the keyboard print? The next, more common reason is the lack of drivers for especially if we are talking about a multifunctional device with a large number of additional buttons. If the device refuses to work, it is recommended that you first reinstall the drivers for it. Or update them.

Typically, keyboards come with a disk with the appropriate software. Next And if the reason lay precisely in the drivers, then everything starts to work. You can optionally turn the device off and on after logging into the operating system. But everything is not always as simple as it seems. After all, a computer is a device that can present various surprises. And fixing them is not always easy or simple. So what other options for the development of events can be identified?

Clogging

Why doesn't the keyboard print? This question sooner or later begins to concern almost every user. This is especially true for those who do not monitor the computer and its components at all. The keyboard does not print some letters? What to do? If we are talking about a device that has been working properly for at least a month, we can only advise one thing - to clean the component.

The keyboard is a device that can get clogged. Dust, food debris, crumbs - all this remains between the buttons. And we are talking about both laptops and desktop computers. Therefore, all keyboards need to be cleaned from time to time. At least once a year. Or as needed. It is also recommended not to eat in front of the monitor. This technique will allow you to avoid clogging the connected device again. By the way, this problem is the most common scenario.

Now it’s clear why the keyboard doesn’t print. Just pay attention to the fact that you should not clean it yourself. Especially if we are talking about a novice user. And even more so, it is not recommended to clean the laptop keyboard yourself. It is better to take the input device to a service center. Almost everywhere offers keyboard cleaning services. In just a few hours, you can fix the problem that has overtaken the user. After cleaning, the keyboard will work at full capacity.

Rearrangement

But these are not all possible scenarios. Sometimes it happens that the keyboard prints the wrong letters. And in this situation it is very difficult to find an explanation for what is happening. After all, the device actually works. Just not the way it should be. There is only one reason that letters print numbers or not what is needed. This is an incorrect assembly of the device. If you disassemble the keyboard, you will notice that each button has its own mechanism. The computer receives a signal from a certain key and prints a particular character. For the convenience of the user, these mechanisms are labeled as buttons on the keyboard. If the latter are swapped, it appears that the device is printing the wrong characters.

Therefore, in this situation there is only one solution - to assemble the keyboard correctly. That is, place the mechanisms located under each key in the desired order. Doing this on your own is very problematic. Therefore, it is best to take the gadget to a service center. If you don’t want to think again about why the keyboard doesn’t print, you shouldn’t wipe and wash this component yourself. Often, problems with incorrect placement of buttons occur precisely after cleaning them yourself. Not the most dangerous, but not very pleasant moment either.

Incorrect assembly

Keyboard buttons not working? What should I do? First of all, don't panic. Secondly, analyze your recent actions with this device. In most cases, the user himself becomes the culprit of problems with components connected to the computer. What to do if If the user tried to figure out the device on his own, it is recommended to immediately take it to a service center.

The cause is incorrect assembly of the input device. Most likely, when the user tried to assemble the keyboard, an important contact came loose somewhere. This is not uncommon and should be kept in mind. You can fix this problem yourself. But users point out that in inept hands the keyboard will never work. Unless it is completely broken. And craftsmen usually manage to disassemble the device the first time and assemble it so that it works fully and without interruptions.

Marriage

What to do if the keyboard does not print? Much depends on the situation. If we are not talking about a new device, then the above scenarios may well be the reason for the failure of the component to work. But what to do when the conversation is about the keyboard you just bought? If all the drivers have been installed, the problem most likely has only one cause - a defect. And here only a complete replacement of the keyboard will help. It is recommended that you immediately contact the store where you purchased the device. There it will be possible to make an exchange. Otherwise, you will have to buy a new gadget.

Incompatibility

What to do if the keyboard doesn't work? You need to find out why the connected device refused to perform its functions. In fact, only in rare cases do users experience serious incidents as the cause. Much more often, all problems can be solved on your own.

Why doesn't the keyboard print? The whole point may be that the device is incompatible with the operating system. This problem appeared quite recently. Most often, users who have Windows 10 encounter this problem. With this operating system, older models do not experience a similar problem. Yes, the keyboard also has its own minimum requirements. And you should pay attention to them. Because you will either have to change the device eventually, or reinstall the operating system to one compatible with the gadget.

Viruses

Keyboard buttons not working? Has this device stopped working at all? If all of the above cases do not apply, you can think about the last, rarest scenario - infection of the operating system. Viruses are the main enemies of the stable operation of computers. They can affect not only software, but also connected devices. For example, under their negative impact the keyboard either does not print, or displays the wrong characters, or it even enters several letters/numbers per press.

There are two ways out: reinstalling the operating system from scratch or treating the computer for the corresponding infection. In the first case, you will have to completely format the hard drive, and only then reinstall the OS. And the second option, as a rule, does not turn out to be effective enough. For this reason, it is recommended to save all data and reinstall the operating system on your computer. This way the virus will disappear 100%.

Any USB keyboard can suddenly outgrow its functionality - even a regular budget one, or one with an advanced design, backlighting and a bunch of 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 a little wider, respectively, due to the USB interface itself. 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 the previous method did not produce successful results, you need to reconnect the keyboard to another USB port. This will either reveal the problematic USB port on the computer, or eliminate one possible cause of the problem. After a malfunction motherboard 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.

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

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 Windows Device Manager. 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 with a direct link in the context menu on the Start button.

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

We confirm the decision.

Reboot the computer.

After rebooting, the keyboard driver will be installed automatically.

For certain models of USB keyboards, manufacturers 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 the 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 be disabled in the 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 point, Windows will use the USB keyboard itself. 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– use of a USB to PS/2 adapter.

What should you do once you enter the BIOS? IN BIOS settings You need to find the USB keyboard support controller parameter. 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!

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.

Mechanical damage

The simplest explanation is mechanical damage to the keyboard. 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.

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.

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.

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.).

Viruses attacked

Sometimes input devices are blocked by malware. If you don’t know why the keyboard on your laptop or computer, and along with it the touchpad and mouse, don’t work, then the problem is most likely due to a virus infection of the system. 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.

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.

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. Typically you will need to click the Delete button to do this, 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.

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.

Sometimes the BIOS does not support USB keyboards. In this case, it is better to entrust the computer setup to professionals from the service center, since it is necessary to reinstall the BIOS. Doing this on your own is quite difficult.

Setting up and optimizing operating systems
