Quit

Selecting QUIT from the Main menu exits the diagnostics and returns you to your operating system environment.

CAUTION: It is important that you quit the diag- nostics program correctly because the program writes data to the computer’s memory that can cause problems unless properly cleared.

Tests in the System Diagnostics

To troubleshoot components or devices, run the appropri- ate test (test group or subtest) in the diagnostics. The

diagnostics exercises the functional components and devices of the computer system more vigorously and thoroughly than they are exercised during normal opera- tion. The diagnostics is organized by components into test groups and subtests within each test group. Each sub- test 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).

Table 5-2 lists the diagnostic test groups, their subtests, and comments concerning their use.
