Enhanced Pre-Boot System Assessment (ePSA)
diagnostics
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
CAUTION: Use the system diagnostics to test only your computer. Using this program with other computers may cause invalid
results or error messages.
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.
