Learning the Basics Powering down the computer 77 Turn Off command The Turn Off command shuts the computer down completely. When you start up again, the computer runs a self-test and loads the operating system. You must open any programs and files you want to use. Factors when choosing Turn Off: ❖ No power is used while the computer is shut down. This is the most efficient mode if you will be away from your computer for an extended time. ❖ Restarting from Turn Off uses the most time and battery power. ❖ When starting up again, the system does not automatically open programs and files you were previously using. Hibernation command The Hibernation command shuts the computer down completely, but it first saves the current state 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 state in which you left it. Factors when choosing Hibernation mode: ❖ 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. ❖ Restarting from Hibernation mode uses less time and battery power than restarting from Turn Off.
