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
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 notebook is in use.
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.

Checking the Battery Level
The notebook features battery-low warning signals that are both audible and
visible. When the battery pack is low, the notebook emits warning beeps
and the battery indicator flashes at regular intervals. Also, you can check
the battery charge level using the onscreen battery gauge.
Using the Onscreen Battery Gauge
To access the onscreen battery gauge, press
Fn-F4

battery level icon displays onscreen.
