Managing Power 3-3
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:
z Charging will not start if the battery’s temperature is below 0°C (32°F)
or above 40°C (104°F).
z The charging process will stop and the Battery Charge Indicator flashes
green and yellow by turns when the battery’s temperature gets above
60°C (140°F). If this happens, the battery pack may be damaged. Please
contact your dealer.
z 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.
