Hi everyone,

I finished my build of Yosemite 10.0.1 and I got everything working except for the backlight. By using AsusNBFnKeys.kext (Thank you so much EMlyDinEsH) I'm now able to change volume by using fn+f3 and fn+f4, and Volume fn+f10 (mute), fn+f11 (volume down), fn+f12 (volume up).

The one thing I cant do is dimm down my screen brightness and it's driving me nuts. 

I actually can get brightness to work natively with the use of my Windows generated DSDT, but I use one from another user fully patched for Graphic card, keyboard backlight.

Here are the two DSDT's if someone knows how to, I appreciate the help.

Thank's in advance.

Hi EMlyDinEsH, I have an ASUS G74SX with backlight keyboard and Media buttons so after search for the solution I found this forum (I thanks good for that) I make all the DSDT edits posted here and installed your kext I tried 1.4 and Zeenbook but none of them work . Did I screw something? I select Yes on booth HasKeyboardBLight and HasMediaButtons.

 

The Screen BackLight control doest work either. I get this on log

This machine has and NVDIA GTX560M and no HD3000 at all, this still could work or is only for integrated GPU´s?

 

and I really really, like to had light come out my keyboard Could you please help me???

I got this with your kext

 

Fn+F1=Sleep

Fn+F2=Wi-Fi ON/OFF

Fn+F3/Fn+F4= Not Working

Fn+F5/Fn+F6= Not Working either

Fn+F7=Freeze I had to reboot 

Fn+F8=Freeze I had to reboot

Fn+F9=Not working

Fn+F10= Mute with Animation

Fn+F11=Volume Down with Animation

Fn+F12=Volume Up with Animation

Fn+ Up= Stop

Fn+ Down=Play/Pause

Fn+Right= Forward 

Fn+Left= Rewind

 

I post my DSDT with all my edits (some name edits, basic patch, Graphics patch for HDMI, and Battery to use vanilla ACPI kexts), I also attach my Vanilla DSDt for compare.

 

As soon I get paid I will donate to support all the hard work!!!

 

Thanks!!!!
