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: • 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. Running the ePSA diagnostics 1 Power-on the computer. 2 As the computer boots, press the F12 key as the Dell logo appears. 3 On the boot menu screen, select the Diagnostics option. 4 Click the arrow key at the bottom left corner.
