Extending Battery Pack Operating Time - Compaq Armada 4200 Reference Manual

Extending Battery Pack Operating Time

Battery pack operating time can be extended by following these
guidelines:
Select the High level of power conservation. See "Setting
Battery Conservation Levels" in this chapter.
Initiate Suspend or Hibernation or turn off the computer when
not in use for several hours.
Reduce the brightness of the display.
Select a shorter screen save timeout.
Avoid unnecessary fast-charge cycles, which reduce the cycle
life of the battery.
Keep a battery pack in the computer when using it with
external power to supply it with a constant charge.
When not in use, any external equipment without its own
power source should be disconnected to avoid draining the
battery pack.
Exit modem programs when not in use.
Remove the PC Card when not in use or turn off power to the
PC Card slots. See Chapter 10, "Connecting External
Devices," for more information about PC Cards.
Store the battery pack in a cool, dry place when not in use.
High temperatures reduce the life of the battery pack and
cause it to lose its charge more quickly. If you are storing the
battery for less than one month, the recommended storage
temperature is 32 F-122 F (0 C to 50 C); for no more than
three months, the recommended temperature is 32 F-104 F (0
C to 40 C); for an unlimited time, the recommended
temperature is 32 F-86 F (0 C to 30 C).
Use the AC Adapter when possible.
