Possible Cause
1. Power On Self Test (POST) has detected
a problem.
1. BIOS setup changes were not saved when you
made them and exited the BIOS setup utility
thus returning to previous settings.
2. The BIOS CMOS hold-up battery has failed.
1. Something is pushing on the Closed Cover
switch. (See Figure 1-5 on page 4.)
2. The notebook is set for an external
monitor only.
Possible Solution
1. See the Power On Self Test (POST) Messages
(pages 130-132) to determine the meaning
and severity of the problem. Not all messages
are errors; some are simply status indicators.
1. Make sure you select Save Changes And Exit
when exiting the BIOS setup utility.
2. Contact your support representative for
repairs. This is not a user serviceable part
but has a normal life of 3 to 5 years.
1. Clear the Closed Cover switch.
2. 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.
