INCREASING BATTERY LIFE
To increase battery life:
1. Power your notebook through the AC or
optional auto/airline adapter whenever possible.
2. If your notebook is running on battery power
all day, connect it to the AC adapter
overnight to recharge the battery.
3. Keep brightness to the lowest level comfort-
able. Your notebook automatically adjusts the
brightness depending on the power source
you are using at the time; the screen will be
brighter when using the AC adapter and
dimmer when using battery power. To
manually change the brightness setting:
Double-click the Task Tray icon on the Taskbar
and select the Power Control tab.
Adjust the backlighting as desired. Lower
(darker) settings save more power.
4. Keep the volume level as low as possible for
comfortable operation.
5. Set the power management for the maximum
Power Savings profile of the PowerPanel set-
tings or set an even longer life combination
with the BIOS setup utility. (See pages 83-84
for instruction on these settings.)
6. Put your notebook in Suspend mode when it
is turned on and you are not actually using it.
7. Disable the parallel and serial ports using the
SETUP utility if no devices are connected.
8. Keep APM enabled.
9. Disconnect USB devices when you do not
need them.
10. Always use fully charged batteries.
CARING FOR YOUR BATTERIES
If your notebook is to be stored for a month or
longer, turn the machine off and remove all
Lithium ion batteries. Store your notebook
and batteries separately in a cool, dry location.
If you store your notebook with a battery
installed, the battery will discharge, and battery
life will be reduced. In addition, a faulty battery
might damage your notebook.
