My laptop is ASUS TP500LN with Intel HD4400 and GeForce 840M graphics. I attach my acpi folder. Thanks in advance.

If you're using Clover, there's no need to put all SSDTs in patched.

Wow... it works! thank you so much friend! foskvs, your're a good man.

yes, i'm using Clover.

foskvs beat me to it but what he's done is patch the DSDT to:

1. add external function _SB_.PCI0.RP05.PEGP._OFF in the DSDT's definition block
2. add an initialisation _INI method (right at the end of the DSDT) that turns the dGPU OFF:

   Scope (_SB)
   {
        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            If (CondRefOf (\_SB.PCI0.RP05.PEGP._OFF))
            {
                ^PCI0.RP05.PEGP._OFF ()
            }
        }
    }

Simple, eh?

 

and gengik84 beat me a few years ago  

All credits to him, of course.

foskvs, Herve, thank you so much, as i'm new in here, i need some times to read hackintosh knowledge,

please wait me a while, thanks again.

If you look at the original DSDT (the one in origin folder) there's no such code. I wonder if somebody tried to patch it before us.

Original:

Patched:

Clearly, that was a very bad try to disable the dGPU (as you said, his gpu is under PCI0.RP05). I applied the patch to the DSDT located in patched folder, because i saw a PNLF device (i'm not aware of hacks that support natively brightness, so i imagine he added that), but maybe it was better to start from the original.

I had not paid too much attention to the original tables, only concentrated on the versions in the patched folder...

Me too. I looked at the original one only after post #9.

post #9. the most perfect, can be successfully installed, thank you very much for your help.
