3.2 Charging and Checking Charging Status
3.2.1 Charging the Battery Pack The battery pack is the internal power source for the tablet PC.
It is rechargeable using the AC adapter. The operating time of a fully charged battery pack
depends on how you are using the tablet PC. When your applications often access peripherals,
you will experience a shorter operating time.
NOTE:
1. Charging will not start if the battery’s temperature is below 0 �C (32 �F). It is also
recommended not to charge the battery when temperature is above 45 �C (113 �F)
2. To prevent damage, the charging process may stop and the Battery Charge Indicator
flashes red when the environmental temperature gets above 55 �C (131�F)
3.2.3 Charging Approaches There is one way recommended to charge the battery pack. By
connecting the AC adapter to the tablet PC and an electrical outlet, the Battery Charge
Indicator on the tablet PC glowed orange 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 Charge Indicator glows green.
CAUTION:
1 After the tablet PC has been fully recharged, do not immediately disconnect and
reconnect the AC adapter to charge it again. The above-mentioned may damage the
battery.
2 During charging, do not disconnect the AC adapter before the battery has been fully
charged; otherwise you will get a prematurely charged battery.
