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 some products, 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 90.
If your PC does not start in Windows, you can use HP PC Hardware Diagnostics UEFI to
diagnose hardware issues.
