Using HP PC Hardware Diagnostics UEFI

HP PC Hardware Diagnostics UEFI (Unied Extensible Firmware Interface) 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.
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 UEFI detects a failure that requires hardware replacement, a 24-digit
Failure ID code is generated. For assistance in correcting the problem, 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.
NOTE: If you need to stop a diagnostic test, press esc.
