Battery Pack
The battery pack is an internal power source for the computer when
no electrical outlets are available. The battery pack can be
recharged with the AC Adapter.
The approximate operating time of the computer with a fully charged
battery pack depends on the applications used, whether power
management is used, the frequency of keystrokes, and the
configuration of the system.
To ensure the longest possible battery life, in terms of both length of
use per charge and number of charge and discharge cycles before
wearing out, please observe these guidelines:
•
Battery packs shipped from the factory are in an almost-
discharged state, so you must charge them fully before use.
•
When charging, always charge the battery pack fully. Even if
you only need to run on battery power for a fraction of the
battery’s capacity, you should not try to give the battery a partial
charge.
•
Normal charging causes the battery pack to heat up slightly. Let
it cool for 15 minutes before you use it.
•
Immediately after the battery pack has been drained of power, it
may be warm to the touch. This is normal. However it should
be set aside to cool for 15 minutes before recharging.
