Power
To conserve battery power:
Lower the brightness level
of the LCD display. The
system will decrease LCD
brightness slightly to save
power when it is not pow-
ered by the AC/DC adapt-
er.
Close modem or communi-
cation applications when
they are not being used.
Remove any unused PC
Cards from the computer
(PC Cards quickly use up
battery power even if the
system
enters
mode).
Disconnect any unneces-
sary external devices.
3 - 10 Battery Information
Battery life may be shortened through improper maintenance. To optimize the life
and improve its performance, fully discharge and recharge the battery at least
once every 30 days.
We recommend that you do not remove the battery yourself. If you do need to re-
move the battery for any reason see
3D Ap-Key Button
The system will default to high performance video when powered by the AC/DC
adapter (the 3D Ap-Key button will be illuminated in blue). If you switch from AC
power to battery power the system will automatically change to a lower performance
video mode setting in order to save power. High Performance Video can not be
enabled when the system is battery powered (see

Recharging the Battery with the AC/DC Adapter
The battery pack automatically recharges when the AC/DC adapter is attached and
plugged into an electrical outlet. If the computer is powered on, and in use, it will
sleep
take several hours to fully recharge the battery. When the computer is turned off but
plugged into an electrical outlet, battery charge time is less. (Refer to
