Using HP PC Hardware Diagnostics (UEFI) (select models only)

HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run

diagnostic tests to determine if the computer hardware is functioning properly. The tool runs outside

of the operating system to isolate hardware failures from issues that may be caused by the operating

system or other software components.

To start System Diagnostics:

1. Turn on or restart the computer, quickly press esc, and then press f2.

After pressing f2, the BIOS searches three places for the HP PC Hardware Diagnostics (UEFI)

tools in the following order:

a. Connected USB drive
