Thank you very much for your guide. I now have brightness adjustment working on El Capitan with HD4400.
Following your guide, I used ACPIDebug and found out _Q11 and _Q12 are the EC methods called for brightness up and down respectively, and by searching for PNP0303 in DSDT I found that KBC0 should be the device name for my keyboard. However, now I am confused by all the keycode stuff. Could you explain what is ADB code and where can I find the appropriate keycode to use? I have ELAN touchpad, and I'm using EMlyDinEsH's driver version 4.6.5.
Read post #1 carefully. The patches/codes required for the ELAN driver are explained.
