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.
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.
