• The batteries can be recharged about 500 times when used as
directed. Excessive rapid recharging decreases battery life.
2.3.2 Conditioning the Battery Pack
Conditioning the battery pack reduces the possibility of memory effect. We
recommend that you condition the battery pack at least once every month,
preferably twice a month.
Follow these steps to condition the battery pack:
1. Disconnect the AC adapter.
2. Turn on the notebook (with the battery pack installed).
3. Press m (during POST) to enter Setup.
4. Leave the machine turned on.
The battery pack begins to use up the battery. Once the notebook has
used up all battery power, the notebook power turns off (the power
indicator turns off). You can then connect the adapter to begin
recharging the battery pack (the battery charging indicator lights up).
Do not turn on the notebook until the battery has been fully charged.
For faster and automatic discharging and charging, you can
use the optional external battery charger.
5. Repeat the conditioning process.
