Power Initiating Standby, Hibernation or Shutdown The following sections explain when to initiate standby or hibernation and when to shut down your tablet PC. When You Leave Your Work Initiating standby clears the screen and uses less power than leaving the tablet PC on. Your work returns instantly to the screen when you resume from standby. Initiating hibernation clears the screen, saves your work to the hard drive, and uses much less power than standby. Shutting down the tablet PC and removing the battery pack is recommended to extend the life of the battery pack when the tablet PC will be disconnected from external power for an extended period. For details on battery pack storage, refer to the "Storing a Battery Pack" section in this chapter. When the Power Supply Is Uncertain Make sure that hibernation remains enabled, especially if you are operating the tablet PC on battery power and do not have access to an external power supply. If the battery pack gets extremely low, hibernation saves your work to a hibernation file and shuts down the tablet PC. HP recommends that if you pause your work when the power supply is uncertain, you do one of the following: ■ Initiate hibernation. ■ Shut down the tablet PC. ■ Save your work, and then initiate standby.
