4. To turn on the computer, press the power button located on
the right side of the front panel, as shown below.
The power indicator below the button lights up. After a few
seconds, the computer starts to perform a diagnostic self test-
a series of checks it completes each time you turn it on to make
sure everything is working correctly.
Note
If you or your dealer have made a major change to your
system, such as adding a disk drive, you may need to wait a
few minutes for your computer to complete power-on
diagnostics the first time you turn it on.
When the system has successfully completed its self test, you
see a prompt to insert a system diskette. (Do not insert a
diskette at this point.)
If necessary, use the controls on your monitor to adjust the
brightness and contrast until characters on the screen are clear
and at a comfortable level of intensity. If your monitor has
horizontal and vertical hold controls, you may need to use
them to stabilize the display.
