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: Any subtest requiring hardware not listed in the
System Configuration
area appears to run,
but the subtest concludes with a status message stating
Component not available
.
