Battery Pack
NOTE:
The battery pack is not charged upon purchasing the computer.
Make sure the computer is turned off and charge it for at least 8 hours
before using it for the first time. Charging automatically starts when the AC
adapter is plugged in to the computer.
The Li-ion battery pack is the internal power source for the computer when
the AC power is “Off” or not connected. It is rechargeable using the AC
adapter. The removable battery pack, with on-line charge capacity, comes
standard with your computer. It has 107 watt operating capacity.
The computer supports up to three Li-ion battery packs: Primary, Media Bay,
and Bay 2 (Media Bay and Bay 2 are optional).
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.
WARNING:
Do not use the battery pack beyond 60
°
C (140
°
F). Permanent
damage to battery cells may occur.
NOTE:
Additional information on proper use and care for the battery is
provided in the “Battery Pack Guidelines” section in Chapter 7.
