There can be a lot of reasons why the user needs to turn off the keyboard - from locking the controls to restricting access from children. How to disable the keyboard in the BIOS in a laptop and what other non-standard way exists?
Disabling the keyboard via BIOS
To begin with, it should be borne in mind that laptop models from such manufacturers as MSI, Lenovo and Acer are best adapted for this. But before you start doing anything, it is recommended that you study the keyboard that came with your laptop. For some models, the BIOS call is carried out through F2, Del, through a combination of buttons or through a specialized hardware button.
In the BIOS section, you need to find an item like USB Support Via. In order for the keyboard to be locked from the child while the operating system is running, it is necessary to set the appropriate parameter value in the BIOS. And that's all - all that remains is to save all the actions performed and restart the laptop.
If we are talking about a more advanced laptop that uses the USB bus to install and connect a keyboard, then there is a more dangerous option to block the keyboard. It is enough to disable (Disabled) the USB Legacy Support item.
But it is not recommended to do this, because in this case the keyboard can be turned on only by clearing the CMOS. And in order to do this, you will need to disassemble the laptop and find the appropriate switch right on the motherboard. In this case, neither external devices nor Bluetooth will work.
We should also mention notebooks from the manufacturer HP, because many of its models are able to block not all buttons from underage children, but only the functional part. Especially for this, HP models have an item called Action Key Mode. If the user sets the parameter value of this item to "Disabled", only the function buttons F1-F12 can be disabled. This will prevent the child from adjusting brightness, sound and other modes.
Fast way
Besides the way the BIOS is used, DOS commands can also be used. This is the easiest way that can be better than BIOS. However, this technique makes the keyboard completely inoperable and inoperable.
In order to disable the functioning of the keyboard in this way, you just need to hold down Win + R and bring up a window. Then enter cmd. This action will bring up the command line - a window with a black background.
In this window, you only need to enter one command - this is rundll32 keyboard, disable. After that, you need to press the Enter button.
By the way, if you make an appropriate shortcut with this command, you can turn off the keyboard just by pressing the mouse button. And to quickly enable it, you just need to create another shortcut, only with the rundll32 keyboard, enable command.
And one more tip: in order not to restart the laptop and turn on the keyboard on a command in the command line, you can use the on-screen keyboard (start-programs-accessibility) and enter rundll32 keyboard, disable
