Battery Charging
When you use the AC adapter to connect your Tablet PC to a power
outlet, the internal battery will automatically begin to recharge. While
the battery is charging, the Battery Charge icon on the Indicator panel
will be active after 6~12 seconds. When the battery is fully charged,
the Battery Charge icon will turn off.
If your Tablet PC is turned off, a fully discharged battery will take
about 3 hours to recharge. If your Tablet PC is turned on and is not in
suspend mode, it twill take about 4~5 hours to recharge the battery.
Refer to the following table:
Charging

Note:
A fully charged Li-Ion battery can run the
Tablet PC for approximately 6.0 hours.
