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.
