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.
