Battery Pack
The battery pack is the internal power source for the Tablet PC. It is
rechargeable using the AC adapter.
NOTE: Care and maintenance information for the battery is provided in the
“Battery Pack Guidelines” section in Chapter 7.
Charging the Battery Pack
NOTE:
 Charging will not start if the battery’s temperature is outside the allowed
range, which is between 0 °C (32 °F) and 50 °C (122 °F). Once the
temperature meets the requirements, charging automatically resumes.
 During charging, do not disconnect the AC adapter before the battery
has been fully charged; otherwise you will get a prematurely charged
battery.
 The battery has a high temperature protection mechanism which limits
the maximum charge of the battery to 80% of its total capacity in the
event of high temperature conditions. In such conditions, the battery
will be regarded as fully charged at 80% capacity.
 The battery level may automatically lessen due to the self-discharge
process, even when the battery pack is fully charged. This happens no
matter if the battery pack is installed in the Tablet PC.
To charge the battery pack, connect the AC adapter to the Tablet PC and an
electrical outlet. The Battery 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.
The charging time is approximately 3 hours (for the standard battery pack)
and 5.5 hours (for the high capacity battery pack) when the power is off.
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.
