Possible Cause
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 1-7 on page 8.)
3. The power management timeouts may be
set for very short intervals and you failed to
notice the display come on and go off again.
1. A foreign object, such as a paper clip, is stuck
between the display and the keyboard.
1. If the spots are very tiny and few in number,
this is normal for a large LCD display.
2. If the spots are numerous or large enough to
interfere with your operation needs.
Possible Solution
1. Use the keyboard or pointer and if that does
not restore operation,push the Suspend/
Resume button. You may want to change
your PowerPanel settings (pages 41–44) or
close your application and go to the setup
utility Power Savings menu (pages 96–101)
and adjust the timeout values to b etter suit
your operation needs.
2. Clear the Closed Cover switch.
3. Press any key or move the pointer, if this
doesn't work press the Suspend/Resume
button.
1. Remove all foreign objects from the
keyboard.
1. This is normal; do nothing.
2. Display is faulty; contact your support
representative.
