3.1.3 Charging the Battery

To charge the battery, place the battery pack inside the battery compartment
and plug the AC adapter into the notebook and an electrical outlet.
Charging Modes
The adapter has three charging modes:
• Rapid charge mode
The notebook uses rapid charging when the notebook is in suspend
mode 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 four
hours.
• Trickle charge mode
When the battery is fully charged, the adapter changes to trickle charge
mode to maintain the battery charge level. This prevents the battery
from draining while the notebook is in use.

We suggest that you charge the battery pack before you go to

sleep, letting it charge overnight before traveling. This ensures

a fully charged battery for use the next day.
