After several days of trying I gave up.
So I have an Acer E5-572G-38HC laptop. Specs :
Cpu:Core i3-4000M 2.4 Ghz
IGPU:HD4600 (working after installing patched kext and framework)
Dedicated GPU: NVIDIA 840M (I want to disable it for power saving)
RAM :4GB
Installed Yosemite 10.10.2 using Unibeast,after installing some kexts for Battery,PS2,LAN,Audio works great without any DSDT or SSDT BUT I have this issues :
-NVIDIA 840M stays on all the time
-Sleep not working (it just restarts)
-Brigtness Fn keys not working and no brigtness slider in display preferences.
-Wifi (AR9565 not supported,I know)
-VGA port (no signal)
-Full screen youtube in Safari (in chrome works fine)
-Full screen in quick time player (in VLC works fine)
-Touchpad gestures (I tried Elan driver kext but not working,kernel panic or does nothing )
-Card reader (Realtek,I tried their driver in .pkg but not working)
For turning nvidia card off I tried :
Disable from _INI (SSDT)
Disable from _REG (DSDT)
The only way to make it disappear from Graphics/Displays is by deleting IONDRVSupport.kext but then audio it's not working anymore (kext not loading).I attached some screenshots with loaded kexts before and after delete.
For brightness I tried :
-Brightness fix (Slider shows in Display preferences but does nothing)
-Brightness fix (haswell) (can't apply this,0 changes) I applied to SSDT-4 and brightness bar shows in Display preferences but again does nothing )
That's my first experience with DSDT/SSDT so maybe I'm doing it wrong.
I attached both original and modified DSDT and SSDT extracted using linux maybe someone can help me. Thanks
