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.

CAUTION: Always keep both battery packs installed, especially when the Tablet PC is

running on battery power. A battery pack can be removed only when it is not being

charged/discharged or if you are hot-swapping the battery pack.

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. The charging time is approximately

5 hours (for the standard battery packs) and 6 hours (for the high-capacity battery

packs) when the power is off.
