101 Learning the Basics Powering down the computer NOTE For more information about the Power Saver utility, see "Optimize" on page 148. Starting again after Shut down To start the computer up again, press the power button until the on/off light changes to blue. If you shut down the computer by closing the display panel, you can start it again by opening the display panel. Using Hibernation Hibernation mode shuts the computer down completely, but it first saves the current mode of the computer to the hard disk. Since Hibernation mode does not require power to maintain the saved information, the system settings are retained indefinitely. Restoring information from the hard disk takes longer than restoring it from memory. When you start up again, the computer runs a self-test, loads the operating system, and then returns to the mode in which you left it. Factors to consider when choosing Hibernation: ❖ While in Hibernation mode, the computer uses no battery power. ❖ Because the mode of the system is held on the hard disk, no data is lost if the main battery discharges. ❖ When starting up again, Hibernation uses less time and battery power than does Turn off computer. ❖ Restarting from Hibernation uses a little more time and battery power to start up than restarting from Standby, because information is being retrieved from the hard disk rather than from memory.
