D - 26 Battery Information
D
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 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. (Refer to
“LED Indica-
tors” on page 1 - 7 for information on the battery charge status, and to “Battery In-
formation” on page D - 25 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 pow-
ered by the AC/DC adapt-
er.
Close modem or communi-
cation applications when
they are not being used.
Remove any unused
ExpressCards from the
computer (ExpressCards
quickly use up battery
power even if the system
enters sleep mode).
Disconnect any unneces-
sary external devices.
