Extending Battery Pack Operating Time
Battery pack operating time can be extended by following these
guidelines:
■
Select the high level of power conservation. See "Selecting a
Battery Conservation Level" in this chapter.
■
Initiate Standby or Hibernation or turn off the computer when
not in use.
■
Reduce the brightness of the display.
■
Select a shorter screen save timeout.
■
Avoid unnecessary fast charge cycles, which reduce the life of
the battery.
■
Keep a battery pack in the computer when using it with external
power to supply it with a constant trickle (low-level) charge.
■
Disconnect any external equipment without its own power source
to avoid draining the battery pack.
■
Exit modem programs when not in use.
■
Remove the PC Card when not in use. These cards may drain the
battery more quickly than expected, even if the computer is in
standby. See Chapter 8, "Working with PCMCIA Devices," for
more information about PC Cards.
■
Store the battery pack in a cool, dry place when not in use. High
temperatures cause a battery pack to reduce its life and lose its
charge more quickly.
If you are storing the battery for less than one month, the
recommended storage temperature is -4°F to 122°F (-20°C to
50°C); for no more than 3 months, the recommended temperature
is -4°F to 104°F (-20°C to 40°C); for an unlimited time,
the recommended temperature range is -4°F to 86°F
(-20°C to 30°C).
■
Use the AC Adapter whenever possible.
