If you are operating the computer on battery power, you can lengthen
the overall operating time by turning it off into Hibernation Mode - Sleep

■
Save your data. 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.
■
Data will be lost if you remove the battery or disconnect the AC adaptor
before the save is completed.

Do not install or remove a memory module while the computer is in
Hibernation Mode. Data will be lost.
