    i will try to boot on it but i suspect hp efi bios will only execute signed efi applications... is it?

    any other suggestion ?

    Tested to boot on some uefi compliant distribution... i have seen some access on cdrom drive but
    nothing else... still black screen

    i dissassembled the entire computer to see if there is a burned component but all seems to be good
    i have unplugged the cpu and replugged it. verified all connectors... still the same
