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.
If your PC will not boot into Windows, you can use HP PC Hardware Diagnostics UEFI to diagnose
hardware issues.
When HP PC Hardware Diagnostics Windows detects a failure that requires hardware replacement, a 24-digit
Failure ID code is generated. For assistance in solving the problem:

automatically filled in. Follow the on-screen instructions.

Contact support, and provide the Failure ID code.
NOTE: To start diagnostics on a convertible computer, your computer must be in notebook mode, and you
must use the attached keyboard.
