Battery Pack
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.
NOTE: Care and maintenance information for the battery is provided in the “ Battery
Pack Guidelines” section in Chapter 7.
