Power
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.
