This article provides methods to disable the built-in keyboard on Windows and Linux laptops. For Windows, the user needs to run the command "sc config i8042prt start= disabled" with administrator privileges and then restart the system to disable the keyboard. To enable it again, the same command should be used with "start= demand". For Linux, the user needs to install "xorg-xinput" package and use the "xinput --list" command to find the ID of the keyboard. To disable it, the command "xinput set-prop [keyboard ID] "Device Enabled" 0" should be used, and to enable it again, the command "xinput set-prop [keyboard ID] "Device Enabled" 1" should be used.

Windows#

Disable#

Run cmd as administrator and enter the following command:

sc config i8042prt start= disabled

Restart your laptop afterwards.

Restore#

Follow the same steps as disabling, but change the command to:

sc config i8042prt start= demand

Note: Manjaro requires

sudo pacman -S xorg-xinput

to be installed in order to use the xinput command.

Open the terminal and enter xinput --list to get the list of devices:
