- Troubleshooting
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.
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.
The application display
uses only a portion of your
screen and is surrounded
by a dark frame.
A running application
doesn’t support the
native pixel resolution
and display compres-
sion is enabled.
Display compression gives a clearer but smaller display for appli-
cations that do not support the native pixel resolution. You can fill
the screen but have less resolution by changing display compres-
sion settings.
See “BIOS Setup Utility” on page 39.
