11 Using HP PC Hardware Diagnostics UEFI
HP PC Hardware Diagnostics UEFI (Unied 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.
NOTE: For Windows 10 S computers, you must use a Windows computer and a USB ash drive to download
and create the HP UEFI support environment because only .exe les are provided. For more information, see
Downloading HP PC Hardware Diagnostics UEFI to a USB ash drive on page 42.
If your PC does not start in Windows, you can use HP PC Hardware Diagnostics UEFI to diagnose hardware
issues.
