Battery and Power Management

This chapter explains how to charge your computer's standard or an optional
secondary battery and how to keep them in good condition. It also explains how you
can use the power management features to maximize battery life while operating
under battery power.

Battery Pack

The removable battery pack is installed in the base of the computer. If you have an
optional secondary battery pack (Model CE-BL11), you can extend the operating
time of your computer when there is no AC power available. See Changing a Unit
in the Unit Bay of chapter 2 for installing an optional secondary battery pack.
The length of time you can run your computer using a fully-charged battery pack is
variable. If you are using applications that make heavy use of peripheral items such
as the hard disk drive or the CD-R/RW drive, the battery discharges in a shorter
time. If your battery is older and has already been through many cycles of charging
and discharging, it stores less charge. Finally, the temperature and environment can
influence battery life.
After you have operated your computer using battery power only, you will have a
good idea of how long it takes a fully-charged battery to discharge. Use this time as
a standard. If the battery begins discharging in a significantly shorter time, and you
are not using your computer in a different manner, or have not changed the power
management settings, it may indicate a battery problem.
After repeated cycles of charging and discharging, all batteries store
less charge. Expect a gradual decrease in battery life after a few
hundred cycles of charging and discharging. When battery life
becomes too short, ask your local dealer for replacement standard
battery pack.
