The system unit and its components are quite complex equipment, the operation of which is better not to intervene unnecessarily, so as not to lead to the occurrence of any error. However, computer components must be handled no less carefully. Especially with input devices.
The above material will discuss the reasons why the numbers above do not work on the keyboard , as well as what to do if this happens.
Why is this happening?
Quite often, the buttons on the keyboard can fail. This can be caused by a large number of reasons. And not all of them depend on the user.
The culprits of the malfunction may be such details as:
- Dead batteries on the keyboard, which works through a USB adapter or Bluetooth.
- Another cause may be a damaged connector to which the equipment is connected.
- It may happen that the keyboard does not work after cleaning. This is due to the fact that the user could not fully push the keys back. Or it completely damaged the mechanical part of some buttons.
In a word, there are a lot of options. Let’s now figure out how to fix such an unenviable situation.
Question to the cord
If during the work many or even all the keys stopped working, then it is worth checking the cord that connects the keyboard to the system unit. First of all, it is important to check the connecting element coming out of the device itself. Carefully inspect it and make sure that there is no external damage caused by excesses.
Also walk along the entire length of the wire. It is worth paying attention to whether there are cracks or other visible damage somewhere. Make sure that your pet does not dine with the cord (if any).
Change of position
If no damage was found on the cord, you should make sure of something else - maybe the numbers on the top of the keyboard do not work because of the port into which the device itself is connected?
If after reconnecting to all the connectors on the computer, the situation has not changed, then you should try an additional option. Try connecting to another device. If this has not yielded results, then it is worth considering to change the damaged thing.
Cleaning
The reason that the numbers above do not work on the keyboard may be pollution with various debris. For example, crumbs from food. The first thing to do is flip the device over and shake it well so that any remaining debris clogged into the space between the keys will fall out.
You can also try to carefully remove the button caps and clean the surface with a brush. But this must be done very carefully. Otherwise, it is likely that you will only make it worse.
Restart
Sometimes restarting the computer can solve many problems. In such a situation, you should do this:
- disconnect the keyboard from the system unit;
- restart it;
- and in the process connect the keyboard itself.
Although it’s worth being honest, the chance that this will work is extremely small.
Lack of drivers
Sometimes the numbers on the top of the keyboard do not work due to outdated or missing drivers. There are two ways to solve this problem. The first is quite simple:
- go to the keyboard manufacturer’s website on the Internet;
- go to the page with downloading drivers;
- select your device from the list and download the software.
However, not all peripheral components have their own sites (for example, if the manufacturer is unknown).
Then the keyboard drivers can be updated or installed in another way:
- launch the search window by clicking on the corresponding icon of the Start menu panel;
- in the search bar, enter the phrase "Device Manager" and run the standard application found;
- in the list that opens, find your keyboard among the connected devices;
- right-click on its logo and select the driver update function.
