Problem
The display goes blank by itself after you
have been using it.
T r o u b l e s h o o t i n g
Possible Cause
3. The angle of the display and the brightness
settings are not adequate for your
lighting conditions.
4. The power management timeouts may be set
for very short intervals and you failed to
notice the display come on and go off again.
5. The notebook turned on with a series of beeps.
1. The notebook has gone into Video timeout,
Standby mode, Suspend mode or Save-to-Disk
mode because you have not used it for a
period of time.
2. Something is pushing on the Closed
Cover switch. (See Figure 2-2 on page 15.)

Possible Solution
3. Move the display and the brightness control
until you have adequate visibility.
4. Press any key or move the pointer, if this
doesn't work press the Suspend/Resume
button. (The display may be shut off
by Standby mode, Auto Suspend, or
Video Timeout.)
5. Power On Self Test (POST) has detected a
failure which does not allow the display to
operate. Contact your support representative.
1. Use the keyboard or pointer and if
that does not restore operation, push
the Suspend/Resume button. You may
want to change your Power Management
settings (page 48) or close your application
and go to the setup utility Power Savings
menu (page 107) and adjust the timeout
values to better suit your operation needs.
2. Clear the Closed Cover switch.
