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 8.

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 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.

The two battery packs are charged in sequence (Battery 1 first and then Battery 2). 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.
