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.
