    Hello, I have this model and the device is fully working but ' Computrace ' is enabled and locked. I cannot remove it. Can you help?

    I tried using the above BIOS/EC BINs and they did not work with my model for some reason.

    I have attached the Main BIOS file. Hope to hear from you very very soon.

    Kind Regards,
    Daemon

    I tried that one already. With that BIOS, there is no display on screen.

    Tested with your BIOS - Still Active - Cannot be disabled. Check Attached Image.

    Any other solutions?
