Now I meet new problem, I try to patch your "Brightness fix(Haswell)", because my laptop is ThinkPad I use "Rename VID to IGPU", and I get 28 errors...And can u tell me the reason?
Your DSDT contains two VID devices. One at PCI0.VID and another at PCI0.PEG.VID. Makes automatic rename difficult... You will need to do the rename manually, renaming only PCI0.VID to PCI0.IGPU. Go to the full post
