GiovaTrabuzz Posted June 1, 2013 Share Posted June 1, 2013 I am able to use QE/CI, but I still have a problem. When I wake from sleep the pc, the brightness automatically sets to max. I found this post at tonymacx86 where is explained how to fix it, but I am not able to understand: This fix works in case brightness increases after sleep. i know this issue in some laptops using intel graphic chipset and for only intel integrated graphic chipset (hd3000, hd4000) cautions. - remove any kexts related backlight. - PNLF exists in your dsdt - set snb platform id or ig platform id in dsdt 1. HD3000 - find your snb platform id. For macbook pro 8,1 it is 01020400 - open appleintelgraphicsfb.kext with hex editor - find your snb platform id and go to 100700100700 right after your id - replace 1007000010070000 to 121300001213000 - rebuild kernel cache What shell I do?
