Display problems

system displays one or more keyboard error messages.
You may need to update your keyboard driver. Refer to the
documentation that came with the keyboard or to the keyboard
manufacturer's Web site.

Display problems
Here are some typical display problems and their solutions:
The screen is blank.
Display Auto Off may have gone into effect. Press any key to
activate the screen.

options.
If you are using an external monitor:
Check that the monitor is turned on.
Check that the monitor’s power cord/cable is firmly plugged
into a working power outlet.

computer is firmly attached.
Try adjusting the contrast and brightness controls on the
external monitor.
