Managing Power 3-11HibernationNOTE: Make sure that the hibernation feature is enabled in the “When I press thepower button,” “When I press the sleep button,” and “When I close the lid” of the PowerOptions Æ System Settings Properties from the Control Panel Æ Mobile PC inWindows Vista.Hibernation is a very useful feature. People frequently open manyapplications when they use computers. It takes some time to get all theseapplications open and running, and normally they all have to be closedbefore the computer can be turned off.When you use the hibernation feature, you do not have to close theapplications. The computer stores the state of your computer to a file onthe hard disk and then shuts down. The next time you turn on yourcomputer, you return to exactly where you left off.
