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.

Before you remove the battery pack, save your data and shut down the computer, or place the computer into Hibernation Mode. Please be aware that, when placing the computer into Hibernation Mode, the contents of memory will be saved to the hard disk drive, although for safety sake, it is best to also save your data manually.
