Turning On the Computer
1. Before turning on your computer, make sure that all the necessary cables (such as the mouse, keyboard, printer, etc.) are connected to the system unit. Also make sure that the system's power cords are connected to an appropriate power source.
2. Make sure that there are no diskettes in the computer's diskette drive, unless you must boot the system from a diskette, (The term BOOTING means starting the computer.)
3. Find the On/Off switch on each attached device (the monitor, printer, etc.), and place it in the ON position. A device's power switch may not be on the front panel. If not, check the sides and back.
4. Find the On/Off switch on the computer's SYSTEM UNIT its main box, into which all other components are plugged-and place it in the ON position. Most computers take a minute or two to start. Your computer may display under mentioned messages during the start-up process.
After the computer has started, the Windows desktop will appear on your screen.
As simple as it may sound, there is a right way to turn a computer's power on and off. If you perform either of these tasks incorrectly, you may damage its components or cause problems for the operating system, programs, or data files.
