11 Using HP PC Hardware Diagnostics (UEFI)
HP PC Hardware Diagnostics is a Unied 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. Start BIOS:
●
Turn on or restart the computer, quickly press esc.
2. Press f2.
The BIOS searches three places for the diagnostic tools, in the following order:
a. Connected USB drive

on-screen instructions.
