internally. The embedded system diagnostics provides a set of options for particular
devices or device groups allowing you to:
• Run tests automatically or in an interactive mode
• Repeat tests
• Display or save test results
• Run thorough tests to introduce additional test options to provide extra
information about the failed device(s)
• View status messages that inform you if tests are completed successfully
• View error messages that inform you of problems encountered during testing
NOTE: Some tests for specic devices require user interaction. Always
ensure that you are present at the computer terminal when the diagnostic
tests are performed.
For more information, see Dell EPSA Diagnostic 3.0.
