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.
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 159.

Using PCDiagnostics

A diagnostics package for the system is contained on the configuration software CD-ROM 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.
CAUTION
Read help information for a test before running it: the diagnostic
package contains many optional tests that should be used only by a user with
advanced technical knowledge. Inadvertent actions could be damaging, such
as running a hard drive write test on a hard disk. All tests that require
external hardware, user interaction, or are destructive, are disabled in the
default configurations. Before using such a test, make sure you read and
understand the help information for that test.
