Choosing Standby, Hibernation or
Shutdown
When You Leave Your Work
If you plan to resume shortly: Initiating 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 up to 2 weeks.
A battery pack that has been frequently charged and discharged
will support Standby for less time.
If you plan to resume within 2 weeks: Initiating 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: Shutting down the notebook and removing
the battery pack extends the useful life of the battery pack.
Store the battery pack in a cool, dry place. For more battery pack
storage information, refer on this CD to the Hardware Guide,
“Storing a Battery Pack.”
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.
