IMPORTANT! Please note that malfunctions can occur in absolutely any keyboard, regardless of its model, manufacturer or price. Currently, there are a huge number of different models with advanced functionality. Nevertheless, you should be as careful as possible when choosing - some functions that may initially seem attractive will in the future be used very rarely or not at all. Do not overpay for the fact that in the end you do not need it and can only become an extra risk factor for damage.

There can be a lot of reasons why such a keyboard does not work: from the most commonplace to quite complex technical damage.

First of all, be sure to check if the wire is connected. It happens that the user forgets to insert it or the plug accidentally pulls out due to careless movement. Of course, this can not be called a malfunction, but such inattention occurs quite often leads to the fact that the keyboard does not work and nothing can be done with other methods.

Then try inserting the cable into another slot - usually there are several USB ports at once, which allows you to use the other if one of them becomes unusable. In this case, the problem will be solved by itself and it will not be necessary to repair the broken input, unless you need it when connecting any other optional accessories.

But if the connection still does not occur, then most likely the problem is with the driver settings. In this case, you must go to the BIOS. Many users think login in BIOS it will not work, because for this you should press a certain key several times, but the keyboard does not work. But in this way, we can determine at what level the error appeared.

If you can easily enter the BIOS and manage tabs using the keyboard, then most likely the fault appeared at the operating system level, that is, in the operation of the drivers. In this case, you can try reinstalling them.

This is easily done using the "Device Manager" tab. In it, find the "Keyboard" section and delete the first item that opens, which appears in the context menu after clicking on this section.

Then you need to restart your windows computer. After that, insert the keyboard into any port - the drivers should be installed automatically, without any user intervention.

IMPORTANT! Other methods may be installing drivers using the disk that came with the computer, or downloading them from the manufacturer’s official website. It is the company that released your device that should make sure that you have access to the necessary drivers for the keyboard to work correctly. Therefore, do not be afraid that you will have to look for them yourself for a long time.

Another possible cause of a malfunction is that the USB controller may be disabled in the BIOS. This happens if there are any problems with the motherboard. But there are also motherboards in which this function is turned off from the very beginning.

If you had to deal with this situation, then in order for the keyboard to work, you still need to connect another using a different port. After the connection is completed successfully, you must again enter the BIOS. Now you need to find the parameters of the controller.

A little difficulty may arise due to the fact that in some models of motherboards the names may differ, although not very significantly. Knowledge of the English language or a translator can come to the rescue - by translating the name of each item, you can definitely find what you need.

Then you need to enable this feature. Surely next to this option, you will see the mark "Off" in English. Change it so that the USB controller turns on. When everything is ready, be sure to save the settings and exit the BIOS only after that.

The most recent option may be that the failure exists precisely at the keyboard level. This may be mechanical damage or contact failure. In this case, you need to make a decision: either replace the accessory with a new one, or try to repair it yourself if you are sure that you will cope with the task. Detailed instructions can be easily found on the Internet. Carefully study it in advance so as not to bring the keyboard to a state where it cannot be repaired in any way.
