103 Learning the Basics Powering down the computer Factors to consider when choosing Turn Off or Shut down: ❖ No power is used while the computer is turned off. This is the most efficient mode if you will be away from your computer for an extended time. ❖ Restarting from Turn Off or Shut down uses the most time and battery power. ❖ When starting up again, the system does not automatically open the programs and files you were previously using. Restart command Restart is the same as Turn Off or Shut down but automatically powers up the computer. Use it when you need to reload the operating system, for example to activate changes to system settings. Hibernation command The Hibernation command powers off the computer, but it first saves the current state of the computer to the hard disk. Since Hibernation 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 restart the computer, the computer runs a self-test, loads the operating system, and then returns to the state in which you left it. Factors to consider when choosing Hibernation: ❖ While in Hibernation mode, the computer uses no battery power. ❖ Because the state of the system is held on the hard disk, no data is lost if the battery discharges while the computer is in Hibernation mode. ❖ When starting up again, this choice uses less time and battery power than the Turn Off or Shut down option. But it uses a little more time and battery power to start up
