Battery Pack
Your Tablet PC has two battery packs. 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 battery’s 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 two battery packs are charged in parallel. It takes approximately 5 hours to fully
charge the two battery packs when the power is off and approximately 6 hours when the
power is on (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.
