Maximizing Battery Pack Life
Battery pack operating time varies depending on the system
components, options, and applications being used. You can
increase battery operating time by as much as 50 percent by
controlling the energy required by the computer and the energy
stored in the battery pack.
NOTE
:
The display, processor, CD-ROM drive, and hard drive
components use the majority of battery power.
Maximize battery pack life using one or more of the following
methods:
■
Select the High level of power management.
■
Initiate Suspend or Hibernation or turn the computer off when
you are not using it.
■
Reduce the display brightness and select a shorter screen save
timeout.
■
Avoid charging battery packs when it is not necessary.
Unnecessary charging cycles reduce the life of the battery.
■
Keep a battery pack in the computer when you’re using the
computer with external power.
■
Disconnect external equipment that does not have its own
power source. (External equipment connected to the computer
drains the battery pack.)
■
Exit modem programs when you are not using them.
■
Remove a PC Card when you are not using it.
■
When storing the computer for more than two weeks, remove
battery pack(s) and store them separately to reduce the
discharge rate and increase battery life.
■
Storing the battery pack in a cool, dry place when it is not in
use. The recommended storage temperature range for the
battery pack is from -4
°
F to 86
°
F (-20
°
C to 30
°
C). High
temperatures cause a battery pack to lose its charge more
quickly and reduce battery pack life.
■
Format diskettes while using external power when possible.
(Formatting diskettes increases the drain on a battery pack.)
