Power Management
3 - 10 Battery Information
3
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
remove the battery for any reason see
“Removing the Battery” on page 6 - 3 .
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 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. (Re-
fer to
“LED Indicators” on page 1 - 6 for information on the battery charge
status, and to “Battery Information” on page 3 - 9 for more information on
how to maintain and properly recharge the battery pack.)
Conserving
Battery Power
To conserve battery pow-
er:
Lower the brightness lev-
el 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 commu-
nication 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 sleep
mode).
Disconnect any unneces-
sary external devices.
