HP PC Hardware Diagnostics tool on my Z840 says only HP devices supported will not launch

HP Recommended
Microsoft Windows 10 (64-bit)

I've just installed the HP PC Hardware Diagnostics tool on my Z840  but when I start it it puts a dialogue error box up and says 'only HP devices supported' and then will not launch the diagnostics tools.


Thsi is an HP supplied Z840 workstation and all other HP applications seem to be OK i,e the Support Assistant etc.

was this downloaded directly from HP? or did you click on a 3rd party's web site link to download it. if so you may have a outdated of the diag program



next are you running it from the Hard drive or from a USB key?




If the HP PC Hardware Diagnostics cannot load the extended tests from the hard drive, a properly prepared USB device can be used to boot the PC into an extended testing environment. To prepare a USB device, download and install the latest version of HP PC Hardware Diagnostics (UEFI) on a USB device.
  1. Turn off the computer.
  2. Insert the USB device containing the latest version of the PC Hardware Diagnostics into a USB port on the computer.
  3. Turn on the computer, then press the Esc key repeatedly until the Startup menu screen is displayed.
    If you cannot start the computer from the USB storage device, temporarily disable Secure Boot from the BIOS. For instructions to disable Secure Boot, see Secure Boot (Windows 10) or Secure Boot (Windows 😎.
  4. Press F2 to select System Diagnostics.
    Figure : Startup Menu

  5. Select your preferred language from the list.
    The HP PC Hardware Diagnostics home page opens, showing the version number and USB.
