D
Battery life may be shortened through improper maintenance. To optimize the life and improve its perfor-
mance, 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 out-
let. 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. (Refer to “LED Indica-
tors” on page 1 - 7 for information on the battery charge status, and to “Battery Information” on page D - 18
for more information on how to maintain and properly recharge the battery pack.)

Conserving Battery Power
To conserve battery power:
Lower the brightness level of the LCD display. The system will decrease LCD brightness slightly to sa ve power when it is not po we red by
the AC/DC adapter.
Close modem or communication applications when they are not being used.
Remove any unused Express Cards from the computer (Express Cards quickly use up battery power even if the system enters sleep mode).
Disconnect any unnecessary external devices.
