Battery types
The computer has two types of batteries:
■ Battery pack
■ 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 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.
