This section provides a more detailed approach to identifying a problem 
and locating its source.

Preparing the System for Diagnostic Testing

If the checks described in the preceding pages do not correct the problem, 
you may need to run some diagnostics programs. Most diagnostics 
programs require rebooting or the closure of all running software.

1.

Turn off the system and all external peripheral devices. Disconnect all 
of them from the system, except the keyboard and video monitor.

2.

Make sure the system power cords are plugged into a properly 
grounded AC outlet.

3.

Make sure your video display monitor and keyboard are correctly 
connected to the system. Turn on the video monitor. Set its brightness 
and contrast controls to at least two-thirds of their maximum ranges 
(see the documentation supplied with your video display monitor).

4.

If the operating system normally loads from the hard disk drive, make 
sure there is no diskette in drive A. Otherwise, place a diskette 
containing the operating system files in drive A.

5.

Turn on the system. If the power LED does not light, see “Power Light 
Does Not Light” on page 164.

To Run Diagnostics

Before disconnecting any 
peripheral cables from the 
system, turn off the system 
and any external peripheral 
devices. Failure to do so can 
cause permanent damage 
to the system and/or the 
peripheral devices.
