Maximizing the Energy Stored
To maximize the energy stored in the battery pack, follow these guidelines:
• Condition the battery pack as described below at least every 30 days to improve
overall battery performance.
• Keep a battery pack in the Notebook 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
Ä
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 Battery Charge Light
on the front bezel of the Notebook goes out. Do not unplug the AC adapter until the
charging light is off.
2. Unplug the AC adapter and allow the battery to drain until the computer enters
Hibernation mode and turns itself off.
Note: You may use the Notebook while the battery is draining.
Ä
CAUTION:
Do not plug in the AC adapter during this process. If the AC adapter is
plugged in while the battery is draining, begin again with step 1 of the
conditioning process.
3. The battery is reconditioned.
4. Resume normal use of the Notebook with AC power.
