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.
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.
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.
