Battery pack operating time can be increased by as much as 50 percent by controlling the
energy required by the computer and the energy stored in the battery pack.

Minimizing the Energy Required

To minimize the energy required by the computer, follow these steps:
Set the power conservation levels in the Power Management utility to Maximum.
Customize the timeout value to work more efficiently with the applications. The
amount of battery life depends on the values selected.

Maximizing the Energy Stored

To maximize the energy stored in the battery pack, follow these guidelines:
Condition the battery pack at least every 30 days to improve overall battery
performance.
Keep a battery pack in the computer when using it with AC power to supply the
battery pack with a constant trickle charge.
Store the battery pack in a cool, dry place when not in use.

Conditioning a Battery Pack

CAUTION: To avoid a loss of data, ensure that all data is saved before
discharging a battery pack.
To condition a battery pack, complete the following steps:
1. Plug in the AC adapter and allow the battery to charge until the fast charge arrow on the
display disappears. Your battery gauge may read 100 percent for a period of time before the
arrow disappears. Do not unplug the AC adapter until the arrow disappears.
Select Disabled in the Power menu of the BIOS Setup. The system will hibernate after one
hour of being in suspend. By selecting Disabled, the system will not timeout and enter
suspend.
2. Unplug the AC adapter and allow the battery to drain until the computer reaches
hibernation and turns itself off. Do not plug in the AC adapter during this process or
you will need to restart with Step No. 1. You may use the computer while the battery is
draining.
3. Your battery is re-conditioned.
