If Your Keyboard Does Not Work

connector (and not the mouse connector) of the PC.

release it by gently manipulating it with your finger.

is correctly connected but does not work, the power-on password
may be set to "keyboard locked". You will need to enter a password

the case, get your keyboard repaired or replace it.
