Hardware Device Problems
The computer does not recognize a newly installed device.
The device may not be correctly configured in the BIOS Setup program.
Run the BIOS Setup program to identify the new type.
Make sure if any device driver needs to be installed. (Refer to the
documentation that came with the device.)
Check the cables or power cords for correct connections.
For an external device that has its own power switch, make sure that the
power is turned on.
Keyboard and Touchpad Problems
The keyboard does not respond.
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
turn the keyboard upside down to drain the liquid 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 touchpad does not work, or the pointer is difficult to control
with the touchpad.
Make sure that the touchpad is clean.
