[Asus G73sw] How to enable keyboard backlight

[FCU4ever]

I installed succesfully macOS Sierra 10.12.6 on my Asus G73sw laptop.

A lot of hardware have I got working but not the backlight of my keyboard. Can someone help me to get the backlight working?

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

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.....

[ref]FCU4ever[/ref], but ur brightness keys is _Q0E and _Q0F?

[ref]MaLd0n[/ref],

Don’t know. How can I find out?

[MaLd0n]

[ref]FCU4ever[/ref], with debug.kext from rehabman is a good way

[FCU4ever]

[ref]MaLd0n[/ref],

I did the following things:

1) Install the kext: https://github.com/RehabMan/OS-X-ACPI-Debug

2) Apply "Add DSDT Debug Methods" and "Instrument EC Queries" that are under Brightness Fix.

3) Save the DSDT and restart

But no logging in System.log after pressing FN + F5 of FN + F6

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

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
