Battery pack
The computer uses a battery pack that gives you long use between charges.

Battery pack characteristics

The battery pack has the following characteristics:
• Employs current battery technology standards
• Battery-low warning
When the battery charge level becomes low, the status indicator of the
computer flashes at regular intervals. This tells you that the battery powe r is
critically low (and you should save your work ). You can correct this situation
by recharging the battery pack.
Whenever possible, use the AC adapter . The batter y wil l come in han dy when you
travel or during a power failure. It is advisable to have an extra fully-charged
battery pack available as backup.

Using a battery pack for the first time

When using a battery pack for the first time, follow these steps:
1. Connect the AC adapter to a power source and to the computer and fully
recharge the battery.
2. Disconnect the adapter to use up the battery before recharging again.
You only need to do this once or twice with a new battery or with a battery that's
been stored without being used for a long time. If the computer is to be stored for
more than two weeks, we suggest you remove the battery pack. Battery power
from a fully charged battery pack depletes in roughly a day with the computer in
Standby mode, a month in Hibernation mode or when power is off.
Warning! Do not expose battery packs to temperatures below 0ºC (32ºF) or
above 60ºC (140ºF). This may adversely affect the battery pack.

Installing and removing the battery pack

Important! Before removing the battery pack, make sure that you have an
AC adapter conn ected to the com puter; otherwis e, turn off the co mputer.
