90 - Troubleshooting
The notebook turned on
with a series of beeps and
the built-in display is blank. Power On Self Test has
detected a failure which
does not allow the dis-
play 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,
Sleep mode, or Save-
to-Disk 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 tim-
eout values to better suit your operation needs.
The power manage-
ment timeouts may be
set for very short inter-
vals and you failed to
notice the display come
on and go off again. Press any button on the keyboard, or move the mouse to restore
operation. If that fails, push the Suspend/Resume button. (The dis-
play may be shut off by Sleep Mode, Auto Suspend or Video Tim-
eout)
Your display won’t turn on
when the system is turned
on or when it has resumed. The system may be
password-protected. Check the status indicator panel to verify that the Security icon is
blinking. If it is blinking, enter your password.
The Built-in Display does
not close. A small foreign object,
such as a paper clip, is
stuck between the dis-
play and keyboard. Remove all foreign objects from the keyboard.
The display has bright or
dark spots. If the spots are tiny and
few, this is normal for a
large LCD display. This is normal; do nothing.
If the spots are numer-
ous or large enough to
interfere with your oper-
ation needs. Display is faulty; contact your support representative.
