[Asus G73sw] How to enable keyboard backlight

Recommended Posts

[ref]MaLd0n[/ref],

I've patched the DSDT by myself with the info on OSXLatitude. And guess what, I've got my backlight working and can control them with FN+F3 an FN+F4 :frantics

Now I want the brightness keys getting work. I've tried the patch (see attachment) but with no luck. Than I saw a solution but I don't know how to get that into my DSDT.....

Followed the guide. In the syslog I see that FN + F5 (brightness up) is Q0E and FN + F6 is Q0F. My keyboard device is PS2M z05qhc6anp4.38.07.png

and SBRG is the device name. So I edit the code to

into method label _Q0E replace_content
begin
// Brightness Down\n
Notify(\_SB.PCI0.SBRG.PS2M, 0x0205)\n
Notify(\_SB.PCI0.SBRG.PS2M, 0x0285)\n
end;
into method label _Q1F replace_content
begin
// Brightness Up\n
Notify(\_SB.PCI0.SBRG.PS2M, 0x0206)\n
Notify(\_SB.PCI0.SBRG.PS2M, 0x0286)\n
end;

 

compiled my DSDT with no errors, copied to my EFI folder, reboot. Still can't change my brightness :(

Tried with no luck :( still can't control the brightness with the FN keys...

Maybe I need to use the patch from this guide: https://osxlatitude.com/forums/topic/1968-fn-hotkey-and-als-sensor-driver-for-asus-notebooks/?tab=comments&_fromLogin=1

but how can I add this

      Method (_Q0E, 0, NotSerialized)  
       {
           If (ATKP)
           {
               \_SB.ATKD.IANE (0x20)
           }
       }
       Method (_Q0F, 0, NotSerialized) 
       {
           If (ATKP)
           {
               \_SB.ATKD.IANE (0x10)
           }
       }

to my DSDT?

Attached my DSDT
