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 LED light on the display stops
blinking. Your battery gauge may read 100 percent for a period of time before LED light on the display
stops blinking. Do not unplug the AC adapter until the arrow disappears.
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.
4. Plug in the AC adapter and begin using the computer.
