Need help disabling NVIDIA Optimus!!

[kosakgroove]

Hello users of this amazing forum!
I am a long time reader and I've always admired the talent of the moderators here, we've come a long way... I've successfully set up a dual boot between windows 8.1 and OS X 10.10.4, using Clover. I've an ASUS X550LDV with the following specs:
Intel core i7(haswell)
Intel HD4400
Nvidia geforce 820m
Realtek ALC233

I've managed to get everything working properly, full qe/ci, ethernet, sound, headphones, touchpad, usb, brightness, fn keys.
The only thing I've left to do is patch my dsdt so that the Nvidia card is disabled with OS X, to save some battery and lower the temperature.
It's been 6 months of trial and error on this computer View attachment patched-dsdt+ssdt0.zipView attachment origin.zipView attachment ioreg.zip cause I've never been good at ACPI language or DSDT patching.

I would appreciate a lot if anyone would take the DSDT I've attached and Disable NVIDIA.
Thanks so much

Please sir,
I respect that point of view towards my situation, but I've been trying to learn ACPI language, and it's come to no use. I would more than gladly have someone disable the nvidia card, because i am gonna be using this one for the uni, as they require OS X programs for our course, and it's really gonna be a pain to have to charge it this often, while away from home.

I hope you understand my situation, and I post again my dsdt and ssdt that i am currently using in efi partition, clover acpi patched
All in hope I could have this big battery life boost, because OS X is running as smooth as it can.

Thanks for everything any which way.

There is a guide for disabling Nvidia via DSDT/SSDT patching linked from the FAQ.

Please follow it with the example files before attempting with your own.

I've been trying these last days, and I've somehow improved my performance, enabling SpeedStep.
I tried all the methods I know to disable the card but no luck...
These are my DSDT and SSDT
I can't understand the error, or where the code fails

Your files have a mix of GFX0 and IGPU. Renames must be applied equally.

Thanks for the advice! I've corrected that, but it still shows nvidia card as a screen, meaning it's still on.Could you take a quick look now?
