Using HP PC Hardware Diagnostics (UEFI) –
Windows 10
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.
When HP PC Hardware Diagnostics (UEFI) detects a failure that requires hardware replacement, a 24-digit
Failure ID code is generated. This ID code can then be provided to support to help determine how to correct
the problem.
NOTE:
To start diagnostics on a convertible computer, your computer must be in notebook mode and you
must use the keyboard attached.
