Battery Pack
The battery pack is the internal power source for the Tablet PC. It is rechargeable
using the AC adapter.
The operating time of a fully charged battery pack depends on how you are using
the Tablet PC. When your applications often access peripherals, you will
experience a shorter operating time.

NOTE:
Charging will not start if the battery’s temperature is below 0 °C (32 °F) or
above 40 °C (104 °F); the charging process will stop if the battery’s
temperature gets above 60 °C (140 °F). To avoid damaging the battery under
this situation, disconnect the AC adapter and wait for the battery to return to
room temperature before charging again.
During charging, do not disconnect the AC adapter before the battery has
been fully charged; otherwise you will get a prematurely charged battery.
To charge the battery pack, connect the AC adapter to the Tablet PC and an
electrical outlet. The Battery Charge Indicator ( ) on the Tablet PC glows amber
to indicate that charging is in progress. You are advised to keep the Tablet PC
power off while the battery is being charged. When the battery is fully charged, the
Battery Charge Indicator glows green.
It takes approximately 2 hours to fully charge the Li-Ion battery pack at a room
temperature of 25 °C (77 °F) (may need a longer charging time at lower
temperatures).
CAUTION: After the Tablet PC has been fully recharged, do not immediately
disconnect and reconnect the AC adapter to charge it again. Doing so may
damage the battery.
NOTE: The battery level may automatically lessen due to the self-discharge
process (0.21% per day), even when the battery pack is fully charged (100%). This
happens no matter if the battery pack is installed in the Tablet PC.
