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 Guidelines” section in Chapter 6.
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, place your Tablet PC in the charging cradle, and
connect the AC adapter to the cradle 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 4 hours to fully charge the battery pack when the
power is off and approximately 6 hours when the power is on (may need a
longer charging time at lower temperatures).
