anyone can advice in how we can do it .. is it via patching dsdt or ssdt files .. or how .. please we want to enrich this forum with lots of information and computer tactics and tricks to achieve good knowledge levels ..

i use the edp ssdt  and dsdt and config list file for the broadwell lenovo z51 70 ( not the amd ) and it is working fine (ver 10.11.3 (15D21).
