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, Bay1,
and Bay2 (Bay1 and Bay2 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.
