22 Chapter 03: Battery Usage and Care
NOTE: This procedure will take a while as the system will discharge the
batteries and then charge them again. Make sure you have some time
before performing this routine. This routine might be better run at the
end of the day.
If you are still having problems, contact your dealer and arrange
for replacements.
In general, running the system until a “Battery Low” warning
indicator appears and then fully charging the battery (full
discharge/charge cycle) will ensure the accuracy of the battery
status gauge and prolong the battery’s charge efficiency.
Running your system until the batteries are almost totally
drained, like described in the calibration routine, on a regular
basis is not recommended as it can damage the battery’s ability
to hold a charge.
Charging the Batteries Under Typical Conditions
When you connect the computer to an electrical outlet, the
Smart Battery IC in each battery pack checks its charge level and
temperature status. If charging is necessary, the corresponding
battery indicator on the front of the tablet will glow orange and
the AC adapter will automatically begin charging the batteries.
When a battery is fully charged, its corresponding indicator will
change to green and the battery’s charge will be maintained
while connected to the external power source. When the
computer is disconnected from the electrical outlet, the battery
indicators will turn off.
NOTE: The time to fully recharge both batteries is approximately
120 ~ 160 minutes when the computer is powered off. The time to
fully recharge the battery when the computer is in use varies
according to the power requirements of the operations that the
computer is performing while charging.

Environmental conditions can affect the ability of the computer
to charge the battery. If the battery is too hot from either being
