Battery Pack
The battery pack is hot-swappable design as well as the internal power source for Tablet. It
is rechargeable by using the AC adapter.
 Hot-swappable features
 Main Battery (2570mAh) supports hot-swappable and back-up battery(700mAh, non-
removable) can provide provisional(30sec to 45sec) power to remain system awake
until new main battery(2570mAh) reload.
 Typical hot-swappable procedure:
- Step1: Main battery(2570mAh) unloaded by latch unlocked
- Step2: LCD backlite turned off (system is still waking)
- Step3: Another main battery(2570mAh) reloaded by latch locked (click)
- Step4: LCD backlite turned on
 Charging the battery pack
 Charging will not be started if battery pack’s temperature is out of allowed range which
is between 0°C(32°F) and 45°C(113°F). Once the temperature meets the requirements,
charging automatically resumes.
 At the period of charging, please do not disconnect the AC adapter prior to fully-charge
of battery, 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 70% of total capacity in the event of high temperature
conditions. Under this circumstances, the battery will be considered as fully charged at
70% capacity.
 The battery level may automatically be reduced due to self-charge even when the
battery pack is fully-charged (100%). Please be cautious that it happens no matter
whether the battery pack is installed in the Tablet.
To charge the battery pack, connect the AC adapter to the Tablet and an electrical outlet.
The battery indicator on front panel side shows amber to indicate charging status. Users will be
suggested to remain Tablet power off while charging. Once battery is fully-charged, the battery
indicator will be green.
It is expected approximately 3 hours to fully charge the battery pack when the power is OFF
while approximately 3.5 hours when the power is ON (may need a longer charging time at lower
temperature)
