How to include a keyboard on the computer, and what are the pitfalls?

It may be that one of the interfaces of the personal computer is not detected. Quite often this applies to the keyboard. Within the framework of the article, we will consider what can lead to this and how to correct it. In addition, the issue of including a virtual keyboard will be considered. After all, it can only be used with a mouse to work with a computer.

Why can not the keyboard work?

The following factors may serve as a cause of the malfunction:

1. The keyboard connector disconnected from the computer.
2. There were hardware malfunctions.
3. The operation of the keyboard is blocked by a key on the system unit.
4. The XT / AT switch is in the wrong position.

Below we will discuss the steps that will explain how to enable the virtual keyboard on the computer in various cases.

Detaching the connector

This is the most trivial and common cause. The connector must be connected to the system unit (on its rear panel) and to the keyboard itself. To eliminate this problem, it is enough just to securely fix the cable that they must be connected. Depending on the hardware features or errors, you may need to reboot so that the computer "sees" the device.

Key lock

This method is used to prevent unauthorized access to the computer. Usually the mechanism is such that a special lock is placed on the front panel of the system unit. And with the help of the key in the complete set it is possible to completely block the operation of the keyboard. When you try to use it, the screen will display the message: "Keyboard is locked". To switch to the operating mode, you need to turn the key to the "open" position and necessarily restart the computer.

Incorrect setting of HT / AT switch

It depends on what kind of hardware is currently being used. Look at the bottom of the keyboard. If you notice a switch, move it to another position. There is a small chance that the computer can not detect the device, so it must be rebooted.

Hardware Fault

If none of the above methods has given you an answer to the question of how to include a keyboard on your computer, then perhaps the matter is in 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 verify the functionality. Some devices can even define the nature of the damage with the help of three LEDs in the upper right corner.

Special abilities

What if the data entry device is needed to send a message, and the previous answers did not help? Well, now you will get an answer to the question about how to turn on the keyboard on the computer screen. To make a one-time start, go the following way:

1. Start.
2. All programs.
3. Standard.
4. Special abilities.
5. Screen keyboard.

Agree, not difficult. We know how to turn on the keyboard on the 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 change its size at your discretion.

Full time job

And how to enable the virtual keyboard on the computer so that it runs with the operating system (if the new device is not expected in the near future)? To do this, go to the above path, but instead of the fifth step, go to the "Accessibility Center". Start the on-screen keyboard and click on the "Show all parameters" link, which is located at the bottom.

Using

We figured out how to turn on the keyboard on the computer. And there are tips for using it? Yes. For printing, simply click on the letters with the mouse cursor. Also, the on-screen keyboard has an additional numeric keypad. To see it, click on the "Options" button, which is located in the lower right corner. A window appears in which you need to tick the "Enable numeric keypad" check box. Then click the "Save" button. To disable the checkmark, you must remove it. We figured out how to turn on the keyboard on the computer, but here's what to do with the function buttons? Click on Fn. As you can see, all the function buttons from F1 to F12 appeared on the virtual keyboard. However, with a "one-time" startup, this function will not be available.

Job

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. Do you know how to turn on the sound on the computer keyboard , for example ? Yes, there is such a function. You can right now restart the computer and use it when loading such keys:

1. F10. This is if you want to mute the sound at all.
2. F11. Click on it if you want to make it quieter.
3. F12. This key makes the sound louder.

Surprised? But that is not all. Do you know how to turn on the computer using the keyboard? Yes, there are no typos - with the help of this device you can actually run the computer. You can try it yourself - you just need to hold down the Ctrl + Esc keys at the same time. The computer can also be turned off using the keyboard. But there are those nuances that you need to work with the BIOS for this.

Conclusion

As you can see, you can do without a keyboard. It can be successfully replaced with a virtual analog. But the use of the latter in the conditions of the game will be quite problematic. Now that you know how to include a keyboard (both conventional and virtual) on your computer, working on the computer will be even easier.
