74
Possible Cause
1. You are running an application which uses
a great deal of power because of frequent hard
drive access or CD-ROM access, use of a
modem PC Card or of a LAN PC Card.
2. The power savings features may be disabled.
3. The brightness is turned all the way up.
4. The battery has been exposed to
high temperatures.
5. The battery is too hot or too cold.
(See Batteries on page 23.)
6. The batteries are very old.
Possible Solution
1. Use a Power adapter for this application
when at all possible.
2. Check the Power Management and/or setup
utility settings in the Power menu and
adjust according to your operating needs.
3. Turn down the brightness adjustment. The
higher the brightness the more power your
display uses.
4. Replace the battery.
5. Restore the notebook to normal operating
temperature. (The Charging icon on the
Status Indicator panel will flash when the
battery is outside its operating range.)
6. Replace the batteries.
