The following subsections provide a more detailed approach to identifying a problem

and locating its source.

Preparing the System for Diagnostic Testing

Caution: Turn off devices before disconnecting cables: 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.

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. Turnon thevideo monitor. Setits brightnessand contrast controls to atleast

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 105.

Using PCDiagnostics

Adiagnostics package forthe systemis containedon theconﬁguration softwareCD that

comes with the system. For documentation about the test modules, see the Diagnostic

help disks that end with the extension .HLP. They are ASCII ﬁles that you can print to

form a manual of all tests in this product.

• The program called Testview uses a simple DOS-based menu system.

• The program called T.EXE is a noninteractive test executable used to run test

program modules from DOS batch ﬁles.

• The README.TXT ﬁle for diagnostics tells how to install the program.
