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.
NOTE: Care and maintenance information for the battery is provided in the
“Battery Pack Guidelines” section in Chapter 7.
Charging the Battery Pack
NOTE:
Charging will not start if the battery’s temperature is below 0C (32F) or
above30C (86F).
The charging process will stop and the Battery Charge Indicator flashes
green and yellow by turns when the battery’s temperature gets above 60C
(140F). 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. The Battery Charge Indicator (
) on the
computer glows yellow to indicate that charging is in progress. You are
advised to keep the computer power off while the battery is being
charged. When the battery is fully charged, the Battery Charge Indicator
is off.
It takes approximately 3 hours to fully charge the Li-Ion battery pack when
the computer is off, and approximately 6 hours to fully charge the Li-Ion
battery pack when the computer is on.
