Troubleshooting
The display goes blank by
itself after you have been
using it.
The notebook has gone into
Video Timeout, Standby
Mode, or Hibernate Mode
because you have not used it
for a period of time.
Press any button on the keyboard, or move the
mouse to restore operation. If that fails, push the
Suspend/Resume button. Check your power
management settings, or close your applications and
go to the Power Savings menu of the setup utility to
adjust the timeout values to better suit your opera-
tion needs. See “BIOS Setup Utility” on page 31.
The power management time-
outs may be set for very short
intervals and you didn’t notice
the display come on and off.
Press any button on the keyboard, or move the mouse
to restore operation. If that fails, push the Suspend/
Resume button. (The display may be shut off by
Standby 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 the 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 enough to interfere with
your operation needs.
Display is faulty; contact your support
representative.

screen but have less resolution by changing your
display compression setting, (See the Video Features
submenu, located within the Advanced menu of the
BIOS. See “BIOS Setup Utility” on page 31.
