Battery Pack
The battery pack is the internal power source for the computer. It is
rechargeable using the AC adapter.
The operating time of a fully charged battery pack depends on how you
are using the computer. When your applications often access peripherals,
you will experience a shorter operating time. In low temperature
environments, the user is recommended to turn on the system using AC
power
NOTE: Care and maintenance information for the battery is provided in the “Battery
Pack Guidelines” section in Chapter 7.
Charging the Battery Pack
NOTES:
Charging will not start if the battery’s temperature is below -5 °C (23 °F) or above
46 °C (115 °F).
The thermal protection of battery pack is 75 °C (167°F) for both Charge and
discharger mode. In any case, once the temperature of battery pack reach to
75°C(167°F), the battery pack will cut off the output and input MOSFET
immediately, the means is battery stop the charge and discharge. If this happens,
the battery pack may be damaged. Please contact your dealer.
During charging, do not disconnect the AC adapter before the battery has been fully
charged; otherwise you will get a prematurely charged battery.
To charge the battery pack, connect the AC adapter to the computer and
an electrical outlet. Battery status indicator (
) will light amber when
battery is charging, and light green when battery is charged full. Battery
low indicator will blink amber when battery capacity is below 10
percentages.
It takes approximately 180 minutes (3 hours) to charge the battery pack
when the computer is off and 240 minutes (4 hours) to fully charge the
battery pack when the computer is on.
CAUTION: After the computer has been fully recharged, do not immediately disconnect
and reconnect the AC adapter to charge it again. Doing so may damage the battery.
