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
specific devices require user interaction. Always ensure that you
are present at the computer terminal when the diagnostic tests are
performed.
