Choosing Standby, Hibernation Or Shutdown - HP Notebook Reference Manual

Power
Choosing Standby, Hibernation or
Shutdown
If you plan to resume shortly: Initiate Standby for shorter times
and Hibernation for longer times or power conservation.
The amount of time a battery pack can support Standby or
Hibernation or hold a charge varies by notebook configuration
and the condition of the battery pack.
Initiating Standby clears the screen, uses less power than
leaving the notebook on, and your work returns quickly to
the screen when you resume from Standby. A fully charged
new battery pack can typically support Standby for up to 48
hours.
Initiating Hibernation clears the screen and uses much less
power than Standby. Returning to work saved in Hibernation
takes longer than returning to work saved in Standby, but it
is faster than returning to your place manually after
restarting the notebook. A fully charged new battery pack
can typically support Hibernation for several weeks.
If you plan to resume within 2 weeks: Shut down the notebook. If
possible, connect the notebook to external power to keep an
inserted battery pack fully charged.
If the notebook will be disconnected from external power for
more than 2 weeks: To extend the life of an inserted battery
pack, shut down the notebook. Remove the battery pack and
store it in a cool, dry location.
If an external power supply is uncertain, for example, because of
an electrical storm, save your work, then initiate Hibernation or
shut down the notebook.
