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.
