The ePSA is embedded with theBIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set of options for particular devices or devicegroups 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 testingYou can invoke the ePSA diagnostics by tapping F12 key when the system posts and choose ePSA or Diagnostics option on One TimeBoot Menu.CAUTION: Use the system diagnostics to test only your computer. Using this program with other computers may cause invalidresults or error messages.NOTE: Some tests for specific devices require user interaction. Always ensure that you are present at the computer terminalwhen the diagnostic tests are performed.NOTE: Regular ePSA’s run for about 5 to 10 minutes, however, the extended test takes about three and half hours with only 8GBof ram in the system.78 Troubleshooting |
