[Asus G73sw] How to enable keyboard backlight

[onemanosx]

[ref]FCU4ever[/ref], try PS2K instead of PS2M

[MaLd0n]

[ref]FCU4ever[/ref], check [ref]onemanosx[/ref] words, PS2M is a mouse, u need a PS2K, is keyboard

[ref]onemanosx[/ref],[ref]MaLd0n[/ref],

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?

Voodoops2

[onemanosx]

[ref]FCU4ever[/ref], I am not on my machine right now to help you with your DSDT right now, but if you are using emilydinesh fn kext, try removing it and reboot.

[ref]onemanosx[/ref],

Without the kext no FN button work, except the Brightness bar. This goes up and down but without changing the brightness.

When I use the bootflag nv_disable the brightness keys work...... but without the bootflag not

I've patched your DSDT as per

 

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

 

Check if works

Thanks for patching. Unfortunately the brightness isn't going up or down (the brightness bar is well going up or down)

[onemanosx]

[ref]FCU4ever[/ref], no idea why it is not working then

[FCU4ever]

[ref]onemanosx[/ref],

Thanks for help. Hopefully someone else have a solution!

[onemanosx]

[ref]FCU4ever[/ref], try again

Also doesn't work I think the solution can be found in this thread: https://osxlatitude.com/forums/topic/1968-fn-hotkey-and-als-sensor-driver-for-asus-notebooks/?tab=comments&_fromLogin=1 but that thread is dead

Is it possible that the "Brightness fix" from Rehabman repro cause the problem?

[onemanosx]

[ref]FCU4ever[/ref], unlikely.

[FCU4ever]

[ref]onemanosx[/ref],

Okay. The reason I am asking is because that after adding the brightness patch from Rehabman to my DSDT the brightness bar has indeed been added to systempreference but also the brightness of the screen is a lot lower than before the patch. Maybe that is the reason I cant control the brightness with te Fn keys after different patches?

[onemanosx]

[ref]FCU4ever[/ref], if you are using RH brightness kext and ssdt, you are able to adjust the intensity of brightness. But I have not looked into that.

I found this patch. This patch is used for an Asus laptop with Nvidia Graphics card to get the brightness slider working. My laptop is also an Asus and I have the Nvidia Geforce GTX460m inside.

But with this patch I've got 3 compiling errors..... Maybe you can help me?
