[ref]FCU4ever[/ref], similar patch as in your dsdt
Add this patch to the latest DSDT that I had uploaded and remove AsusFN kext from your S/L/E or L/E or Clover/Kexts/Other. Rebuild permissions and reboot.
(might also need to rebuild permissions again and reboot 2nd time)
into method label _Q0E replace_content
begin
// Brightness Down\n
Notify(\_SB.PCI0.SBRG.PS2K, 0x0205)\n
Notify(\_SB.PCI0.SBRG.PS2K, 0x0285)\n
end;
into method label _Q0F replace_content
begin
// Brightness Up\n
Notify(\_SB.PCI0.SBRG.PS2K, 0x0206)\n
Notify(\_SB.PCI0.SBRG.PS2K, 0x0286)\n
end;
In some cases, slider wont adjust brightness. But working FNkeys will adjust the brightness accordingly.
If this doesnt work, then I dont know.
