Charging the battery
To charge the battery, slide the battery pack into the battery bay and
plug the AC adapter into the computer and an electrical outlet.
Charging modes
The adapter has two charging modes:
•
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 3 hours.
•
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 4.5 hours.
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.
Checking the battery level
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.
