Enhanced Pre-Boot System Assessment
(ePSA) diagnostics
CAUTION: Use the ePSA diagnostics to test only your computer. Using
this program with other computers may cause invalid results or error
messages.
The ePSA diagnostics (also known as system diagnostics) performs a complete
check of your hardware. The ePSA is embedded with the BIOS and is launched by
the BIOS 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 specific devices require user interaction. Always
ensure that you are present at the computer terminal when the diagnostic
tests are performed.
