Operating on Battery Power

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 seven 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 computer is in use.
Tip! 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 computer features battery-low warning signals that are both
audible and visible. When the battery pack is low, the computer
emits warning beeps and the battery indicator flashes at regular
intervals. Also, you can check the battery charge level using the
Windows battery meter.
Using the Windows Battery Meter
The Windows battery meter indicates the present battery level.
Simply rest your cursor on the battery meter (or AC plug) icon on
the taskbar to see the present charge level of your battery.
