Power
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 tablet PC on, and your work
returns quickly to the screen when you resume from Standby. A
fully charged new battery pack can support Standby for up to
3 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: 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
tablet PC. A fully charged battery pack supports Hibernation for
up to 3 months.
If the tablet PC will be disconnected from external power for
more than 1 month: Shutting down the tablet PC 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,
“Battery Packs” chapter, “Storing a Battery Pack.”
When the Power Supply Is Uncertain
If power is interrupted while the tablet PC is in Standby, your
unsaved work is saved for up to 1 minute. Any data not saved
during this time will be lost. If power is interrupted while the
tablet PC is in Hibernation, your unsaved work is protected.
Power may be interrupted if the tablet PC is running on external
power from an unreliable power source, on battery power from a
failing battery pack, or during battery pack replacement. If you pause
your work when the power supply is uncertain, Compaq recommends
that you initiate Hibernation or shut down the tablet PC.
