Using HP PC Hardware Diagnostics (UEFI)

HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run
diagnostic tests to determine whether the computer hardware is functioning properly. The tool runs outside
the operating system so that it can isolate hardware failures from issues that are caused by the operating
system or other software components.
To start HP PC Hardware Diagnostics UEFI:
1. Turn on or restart the computer, quickly press esc, and then press f2.
The BIOS searches three places for the diagnostic tools, in the following order:
a. Connected USB drive
