Initiating Standby, Hibernation or Shutdown
The following sections explain when to initiate standby
or hibernation and when to shut down your notebook.
When You Leave Your Work
■ Initiating standby clears the screen and uses less power than
leaving the notebook on. Your work returns instantly to the
screen when you resume from standby.
■ Initiating hibernation clears the screen, saves your work
to the hard drive, and uses much less power than standby.
■ Shutting down the notebook and removing the battery pack
is recommended to extend the life of the battery pack when
the notebook will be disconnected from external power for
an extended period. For details on battery pack storage, refer
to the “Storing a Battery Pack” section, later in this chapter.
When the Power Supply Is Uncertain
Make sure that hibernation remains enabled, especially if you are
operating the notebook on battery power and do not have access
to an external power supply. If the battery pack fails, hibernation
saves your work to a hibernation file and shuts down the
notebook.
If you pause your work when the power supply is uncertain, it is
recommended that you do one of the following:
■ Initiate hibernation.
■ Shut down the notebook.
■ Save your work, and then initiate standby.
