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 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.
HP recommends that if you pause your work when the power
supply is uncertain, you do one of the following:
■ Initiate hibernation.
■ Shut down the notebook.
■ Save your work, and then initiate standby.
