Closed Cover switch. Clear the Closed Cover switch. (See figure 2-3 on

The notebook is set for an
external monitor only. Pressing [F10] while holding down the [Fn] key

The display angle and bright-
ness settings are not adequate
for your lighting conditions. Move the display and the brightness control until
you have adequate visibility.
The power management time-
outs may be set for very short
intervals and you failed to
notice the display come on
and go off again. Press any button the keyboard, or move the mouse
to restore operation. If that fails, push the Power/
Suspend/Resume button. (The display may be shut
off by Standby mode, Auto Suspend or Video

The notebook turned on
with a series of beeps and
your display is blank. Power On Self Test (POST) has
detected a failure that does not
allow the display to operate. Contact your support representative.
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 Power/
Suspend/Resume button. Check your power manage-
ment 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 operation needs.

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.
