The keyboard is an integral part of any PC. It can be connected through different ports, but recently USB devices have become increasingly popular. This is due to the fact that such a connector is present on absolutely any computer, as well as other units to which you may need to connect this accessory, and, moreover, not in a single copy.

But many users have to deal with a variety of problems - the keyboard may suddenly stop working or some errors in its functionality may appear.

If you can correctly determine the cause, then further troubleshooting of the problem will not be difficult and you will not have to seek the expensive help of specialists at all. You will learn about how to correctly diagnose an accessory, what reasons can cause certain malfunctions, as well as ways to eliminate them in this article.

Signs and causes

Let's consider possible malfunctions and the reasons for their occurrence.

IMPORTANT! Please note that operational problems can occur with absolutely any keyboard, regardless of its model, manufacturer or price.Currently, there are a huge number of different models with advanced functionality. However, you should be as careful as possible when choosing - some features that may initially seem attractive will be used very rarely or not at all in the future. You shouldn’t overpay for something that you won’t need in the end and can only become an extra risk factor for breakdown.

There can be many reasons why such a keyboard does not work: from the most banal 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 is accidentally pulled out due to careless movement. Of course, this cannot be called a malfunction, but such inattention occurs quite often and leads to the fact that the keyboard does not work and nothing can be done about it using other methods.

Then try inserting the cable into another socket - usually there are several USB ports at once, which allows you to use another one if one of them becomes unusable. In this case, the problem will be solved by itself and there will be no need to repair the broken input, unless you need it when connecting any other additional accessories.

But if the connection still does not occur, then most likely the problem is related to the driver settings. In this case, you need to go to the BIOS. Many users think that login in BIOS It won’t work, because to do this you have to press a certain key several times, but the keyboard doesn’t work. But this is how we can determine at what level the error appeared.

If you can easily enter the BIOS and control tabs using the keyboard, then most likely the problem 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 the Windows computer. After this, insert the keyboard into any port - the drivers should install 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 manufactured your device that must ensure that you have access to the necessary drivers for the keyboard to function correctly. Therefore, do not be afraid that you will have to search for them for a long time on your own.

Another possible reason for the malfunction is that the USB controller may be disabled in the BIOS. This happens if there is any problem with the motherboard. But there are also motherboards in which this function is disabled from the very beginning.

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

A slight difficulty may arise due to the fact that in some board models the names may differ, although not very significantly.A knowledge of English or a translator can come to the rescue - by translating the name of each item, you will definitely be able to find what you need.

Then you need to enable this feature. Surely next to this parameter you will see the mark “Disabled” in English. Change it to enable the USB controller. 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 breakdown exists precisely at the keyboard level. This could 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 carry out the repair yourself if you are confident that you can handle the task. Detailed instructions can be easily found on the Internet. Study it carefully in advance so as not to bring the keyboard to a state where it cannot be repaired in any way.

What to do when the USB port on your computer does not work

If you are sure that the problem is related specifically to a problem with the USB port, then you can try several ways to fix the problem.

• In most cases, you can figure out the reason and return the nest to service. If it is completely broken and nothing helps, then you will simply have to stop using this particular input. When there are not enough ports, because usually there are several of them on each PC, and there are a lot of accessories connected in this way, you can purchase a special cartridge that will allow you to connect everything that is necessary to work on the computer.
• One solution may be to update the operating system - many users prefer to turn off any notifications and use the same operating system for many years.Unfortunately, with this approach it ends up in a terrible state. Because of this, a large number of problems can arise, so it is advisable to update all the necessary drivers and settings at least once every six months or a year.
• It is possible that the operation of the power supply has also become incorrect due to too long use or any mechanical damage. Because of this, a huge number of accessories may not appear on the computer at all. Then you need to replace the element and the ports will return to normal.
• Also check that the cables are in good condition.
• But it may also be that the problem is still related to the keyboard itself. Try connecting it to a different port, or better yet, to a different device. For example, to a TV equipped with USB ports, or another computer. This way you can make sure that everything is fine with it and that the problems lie in the operation of the computer inputs.

Repairing a completely broken entrance on your own is very difficult. It is better not to try to do this yourself and just stop using this port.

It is possible that the problem lies in the failure of your port or incorrect operation of the operating system. In order to be able to use the purchased accessory, conduct a thorough diagnosis of the computer and the device itself, and if certain causes are found, eliminate them using the knowledge gained after reading the article.
