Getting sleep to work after switching off Nvidia GPU in optimus laptop hackintosh

Asus UX303UB RAM - 8GB / 250GB SSD Intel 520HD integrated graphics Nvidia GeForce 940M Inbuilt USB webcam, inbuilt USB PS2 Elan touchpad, inbuilt USB bluetooth

I have the discrete Nvidia GPU switched off through _OFF method in SSDT (_INI). However, even after patches to _PTS/_WAK in DSDT, I am unable to get sleep functionality to work.

It does work as soon as I remove _OFF from SSDT but not otherwise.

I have tried every method that's been discussed but have unsuccessful.

Let me know if someone has been able to achieve sleep after switching off Nvidia discrete GPU.

Pointers- 1. I'm using USBXHCI kext for USB 3 support. 2. I have followed all other methods like resetting printer prefs etc.
