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. 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.
