Battery Pack
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 Guidelinessection 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 batterys 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 Indicator glows green.
It takes approximately 3 hours to fully charge the battery pack when the power is off
and approximately 3.5 hours when the power is on (may need a longer charging
time at lower temperatures).
