Battery types
The computer has three types of batteries:
■ Battery pack
■ Slice Expansion Battery (optional)
■ Real Time Clock (RTC) battery
Battery pack
When the AC adaptor is not connected, the computer’s main power source
is a removable lithium ion battery pack, also referred to in this manual as
the main battery. You can purchase additional battery packs for extended
use of the computer away from an AC power source.
Do not change the battery pack while the AC adaptor is connected.
Before you remove the battery pack, save your data and shut down the
computer, or set the computer to Hibernation Mode. While entering
Hibernation Mode, the computer saves the contents of memory to the hard
disk drive. However, for safety sake, it is best to save your data manually.
