Using HP PC Hardware Diagnostics UEFI

HP PC Hardware Diagnostics UEFI (Unified Extensible Firmware Interface) allows diagnostic tests to be run 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 the PC will not boot into Windows, 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, the computer must be in notebook mode, and the
attached keyboard must be used.
NOTE: If a diagnostic test needs to be stopped, press esc.
