Charger

To charge the battery, place the battery pack inside the battery compartment and plug the AC
adapter into the notebook and an electrical outlet. The adapter has three charging modes:
Rapid mode
The notebook uses rapid charging when power is turned off and a powered AC adapter is
connected to it. In rapid mode, a fully depleted battery gets fully charged in approximately two
hours.
Charge-in-use mode
When the notebook is in use with the AC adapter plugged in, the notebook also charges the
battery pack if installed. This mode will take longer to fully charge a battery than rapid mode.
In charge-in-use mode, a fully depleted battery gets fully charged in approximately six to eight
hours.
Trickle mode
The adapter charges the battery pack for two hours using trickle current 380mA, then shifts to
1/10 duty pulse trickle charge to keep the battery capacity at 100%.
