D 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 "3D Ap-Key Button" on page 1- 7).
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. (Refer 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 power:
Lower the brightness level of the LCD display. The system will decrease LCD brightness
slightly to save power when it is not powered by the AC/DC adapter.
Close modem or communication applications when they are not being used.
Remove any unused PC Cards from the computer (PC Cards quickly use up the battery
power even if the system enters sleep mode).
Disconnect any unnecessary external devices.
