Possible Solutions
See the POST messages to determine the
meaning and severity of the problem. Not
all messages are errors; some are status indi-
cators.
Make sure you select Save Changes And
Exit when exiting the BIOS setup utility.
Contact your support representative for
repairs. This is not a user serviceable part
but has a normal life of 3 to 5 years.
Clear the Closed Cover switch.
Press the [Fn] + [F7] keys repeatedly until
you have the desired brightness.
Pressing [F10] while holding down the [Fn]
key allows you to change your selection of
where to send your display video. Each time
you press the combination of keys you will
step to the next choice. The choices, in
order are: built-in display only, external
monitor only, both built-in display and
external monitor.
Press any button or key on the keyboard, or
move the mouse to restore operation. If that
fails, push the Power and Suspend/Resume
button. (The display may be shut off by
Standby mode, Auto Suspend or Video
Timeout.)
