Diagnose Hardware Issues on Your Dell Laptop or Desktop

Published Nov 01, 2023

The ePSA is a BIOS feature that helps diagnose hardware issues by scanning various components. To start it, press 'F12' at the Dell logo and select 'Diagnostics' from the one-time boot menu. The test lasts a few minutes and you can view the progress at the bottom of the screen. If an issue is detected, an error code will be provided for a Dell technician to solve.
