SupportAssist diagnostics
About this task
The SupportAssist diagnostics (previously known as ePSA diagnostics) performs a complete check of your hardware. The
SupportAssist diagnostics is embedded in the BIOS and is launched by it internally. The SupportAssist diagnostics provides a set
of options for particular devices or device groups. It allows 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 and provide extra information about the failed device(s)
● View status messages that indicate if the tests are completed successfully
● View error messages that indicate if problems were encountered during the test
NOTE:
Some tests are meant for specific devices and require user interaction. Ensure that you are present in front of the
computer when the diagnostic tests are performed.
