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 (0.21% per day), even when the
battery pack is fully charged (100%). 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.
