Tests in the Dell Diagnostics
To troubleshoot components or devices, run the appropriate test (test group or subtest) in the diagnostics on
your diagnostics diskette. The diagnostics exercises the functional components and devices of your
computer system more vigorously and thoroughly than they are exercised during normal operation. The
diagnostics is organized by components into test groups and subtests within each test group. Each subtest is
designed to detect any errors that may interfere with the normal operation of a specific device of the
computer.
NOTE: Some subtests requiring hardware not listed in the System Configuration area of the
diagnostics screen appear to run, but they conclude with a status message stating Component not
present (or disabled).
The diagnostic test groups, their subtests, and comments concerning their use are listed in Table 2.
