power source for more than two weeks, remove and store the
battery packs.
Proper storage procedures reduce the self-discharge rate of a
battery pack. Store a battery pack in a cool, dry place within the
following temperature ranges.

Maximizing Battery Pack Life
Battery pack operating time varies depending on the system
components, options, and applications used. Battery operating
time can increase by as much as 50 percent by controlling the
energy used by the computer and the energy stored in the battery
pack.
NOTE:
T
he display, processor, and drive components use the
majority of battery power.
To maximize battery pack life, use the following guidelines:
■
Select the High level of power management (not available
under Windows 98). See Chapter 4 for more information on
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.
■
Keep a battery pack in the computer when you are using the
computer with external power.
