Turning Off the Computer
Whenever you turn off your system, follow these steps:
1. Save your data and exit any application program you are
using.
2. Check the hard disk drive light and the diskette drive light(s)
to make sure they are not on. Do not turn off the computer

lose data.

4. Press the power button to turn off the computer.
5. Turn off the monitor, printer, and any other peripheral
devices.
