It may be that one of the interfaces of the personal computer is not detected. Quite often this applies to the keyboard. As part of the article, we will consider what can lead to this and how to fix it. In addition, the inclusion of a virtual keyboard will be considered. After all, with its help you can work with a computer only with the mouse.
Why might the keyboard not work?
The causes of the malfunction can be the following factors:- The keyboard connector is disconnected from the computer.
- There are hardware problems.
- The keyboard is locked with a key on the system unit.
- The XT / AT switch is in the wrong position.
Below we will consider the steps that will explain how to enable the virtual keyboard on the computer in various cases.
Disconnect connector
This is the most trivial and common reason. The connector must be connected to the system unit (on its rear panel) and to the keyboard itself. To fix this problem, all you need to do is fix the cable securely so that they must be connected. Depending on the hardware features or due to errors, a reboot may be necessary for the computer to “see” the device.
Key Lock
This method is used to prevent unauthorized access to a computer. Typically, the mechanism is such that a special lock is placed on the front panel of the system unit. And with the included key, you can completely block the keyboard. If you try to use it, the screen will display a message: "Keyboard is locked". To switch to the operating mode, it is necessary to turn the key to the "open" position and be sure to restart the computer.Incorrect installation of the XT / AT switch
It depends on what equipment is being worked on. Look at the bottom of the keyboard. If you notice any switch, then move it to another position. There is a small chance that the computer will not be able to detect the device, so it must be restarted.
Hardware malfunction
If none of the above methods gave you an answer to the question of how to turn on the keyboard on your computer, then maybe the device itself. Take a picture of his appearance (this will be needed later). Then try to disassemble and clean the contacts. If this does not help, then find the official documentation and look at ways to check the health. Some devices can even determine the nature of the damage using the three LEDs in the upper right corner.
Special abilities
What if the data input device is needed in order to send a message, but the previous answers did not help? Well, now you will receive an answer to the question of how to turn on the keyboard on the computer screen. To make a one-time run, go through the following path:
- Start.
- All programs.
- Standard.
- Special abilities.
- Screen keyboard.
Agree, it’s not difficult. We know how to turn on the keyboard on a computer screen, but is it convenient to use it? Usually it is adjusted to the size of the monitor and has its width, as well as half or a third of the height. Although you can put it in a separate window and resize it as you wish.
Permanent job
But how to enable the virtual keyboard on the computer so that it starts with the operating system (if a new device is not expected in the near future)? To do this, follow the path above, only instead of the fifth step, go to the "Accessibility Center". Launch the on-screen keyboard and click on the link “Display all parameters” located at the bottom.Using

Interaction with the keyboard is not difficult. By the way, working with this device has many different aspects that most people do not know about. For example, do you know how to turn on sound on a computer keyboard? Yes, there is such a function. You can restart your computer right now and use these keys when booting:- F10 This is if you want to turn off the sound at all.
- F11 Click on it if you want to make it quieter.
- F12 This key makes the sound louder.
