83 - Troubleshooting

The display goes blank by 
itself after you have been 
using it.

The notebook has gone 
into Video timeout, 
Standby 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 Power/Suspend/Resume button. 
Check your power management settings, or close your applica-
tions and go to the Power Savings menu of the setup utility to 
adjust the timeout values to better suit your operation needs. See 
“BIOS Setup Utility” on page 39.

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 Power/Suspend/Resume button. 
(The display may be shut off by Standby Mode, Auto Suspend or 
Video Timeout)

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 display does not close.

Foreign object (like 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 numer-
ous or large enough to 
interfere with your oper-
ation needs.

Display is faulty; contact your support representative.

The display is dark when on 
battery power.

The Power Manage-
ment utility default is set 
on low brightness to 
conserve power.

Press [Fn] + [F7] to increase brightness or double-click on the bat-
tery gauge and adjust Power Control under battery settings.
