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 adapter.
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.
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 Adapter
The battery pack automatically recharges when the AC 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 Power & Communication Indicators” on page 2 - 3 for informa- tion on the battery charge status, and to “Battery Information” on page 3 - 21 for more information on how to maintain and properly recharge the battery pack.)
