Troubleshooting

Keyboard, Mouse, and Touchpad Problems
The keyboard does not respond.
z
Try connecting an external keyboard. If it works, contact an authorized
dealer, as the internal keyboard cable might be loose.
Water or liquid is spilt into the keyboard.

Immediately turn off the computer and unplug the AC adapter. Then tilt
the keyboard 90 degrees to the right (where the drainpipe ends are
located) to let the liquid flow out of the keyboard. Make sure to clean
up any part of the spill you can get to. Though the keyboard of your
computer is spill-proof, liquid will remain in the keyboard enclosure if
you don’t remove it. Wait for the keyboard to air dry before using the
computer again.
The numeric keypad is disabled.

Make sure that the
Num Lock
is switched on. (Check if the Num Lock
Indicator glows or not.)
