Charging ModesCharging Modes
The adapter has three charging modes:
q Rapid mode
The computer 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.
q Charge-in-use mode
When the computer is in use with the AC
adapter plugged in, the computer 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.
q Trickle mode
When the battery is fully charged, the adapter
changes to trickle mode to maintain the
battery charge level. This prevents the
battery from draining while the computer is in
use.
Note: We suggest that you charge the battery pack
before retiring for the day, letting it charge
overnight before traveling. This ensures a fully
charged battery for use the next day.
