Choosing Standby, Hibernation or
Shutdown
When You Leave Your Work
If you plan to resume shortly: Initiate Standby. Standby clears the
screen, uses less power than leaving the notebook on, and your
work returns instantly to the screen when you exit Standby. A
fully charged new battery pack can support Standby for 2 days. A
battery pack that has been frequently charged and discharged will
support Standby for less time.
If you plan to resume within 2 weeks: Initiate Hibernation.
Hibernation clears the screen, saves your work to the hard drive,
and uses much less power than Standby. Returning to work saved
in Hibernation takes longer than returning to work saved in
Standby, but is faster than returning to your place manually after
restarting the notebook. A fully charged battery pack supports
Hibernation indefinitely.
If the notebook will be disconnected from external power for
more than 2 weeks: Shut down the notebook and remove the
battery pack. Removing the battery pack extends the useful life of
the battery. Store the battery pack in a cool, dry place. For more
battery pack storage information, see the Hardware Guide,
“Storing a Battery Pack,” on this CD.
When the Power Supply Is Uncertain
If power is interrupted while the notebook is in Standby, your
unsaved work is lost. If power is interrupted while the notebook
is in Hibernation, your unsaved work is protected.
Power may be interrupted if the notebook is running on external
power from an unreliable source or on battery power from a
failing battery pack. If you pause your work when the power
supply is uncertain, Compaq recommends that you initiate
Hibernation, shut down the notebook, or save your work, then
initiate Standby.
