- Troubleshooting
The display goes blank by
itself after you have been
using it.
(continued)
Power management timeouts
may be set for short intervals
and you failed to notice the
display come on then go off.
Press any button on the keyboard, or move the mouse to
restore operation. If that fails, push the Power/Sus-
pend/Resume button. (The display may be shut off by Sleep
Mode, Auto Suspend or Video Timeout)
The display does not
close.
A foreign object, such as a
paper clip, is stuck between
the display and keyboard.
Remove all foreign objects from the keyboard.
The display has bright or
dark spots.
If the spots are very tiny and
few in number, this is normal
for a large LCD display.
This is normal; do nothing.
If the spots are numerous or
large, display is faulty.
Contact your support representative.
The application display
uses only a portion of
your screen and is sur-
rounded by a dark frame.
You are running an applica-
tion that does not support
the system’s native resolution
and display compression is
enabled.
Display compression gives a clearer but smaller display for
applications that do not support the system’s native pixel
resolution. You can fill the screen but have less resolution by
changing display compression settings. These settings can
be changed in the Intel GMA control panel.

external monitor and it
does not display any infor-
