8 Troubleshooting 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: The ePSA diagnostics can be initiated by the FN+PWR buttons while powering on the computer. • 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. Running the ePSA Diagnostics Invoke diagnostics boot by either of the methods that are suggested below: 1. Power on the computer. 2. As the computer boots, press the F12 key when the Dell logo is displayed. 3. In the boot menu screen, use Up/Down arrow key to select the Diagnostics option and then press Enter.
