[Guide] Disabling discrete graphics in dual-GPU laptops

[MateuszCzerkas]

Sorry, but I don’t understand that. I dont have much experience in hackintosh cause I’m a novice. Can I ask you for more detailed instructions or corrected files? I would be thankful.

Edit: I edited DSDT and SSDT and now it's booting normally, but nvidia is still present

"Problem Reporting" files are incomplete.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the tool mentioned in the FAQ, that way it is less likely you'll omit something.

SSDT-9-OptTabl.aml is correct.
SSDT-8-SgPch.aml:
- no need to modify SGON
_INI is:

        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            Store (Zero, \_SB.PCI0.RP05.PEGP._ADR)
        }

Should be:

        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            Store (Zero, \_SB.PCI0.RP05.PEGP._ADR)
            External(\_SB.PCI0.RP05.PEGP._OFF, MethodObj)
            _OFF()
        }

DSDT, EC0._REG is:

            Method (_REG, 2, NotSerialized)  // _REG: Region Availability
            {
                If (LEqual (Arg0, 0x03))
                {
                    Store (Arg1, ECFL)
                }

                If (LAnd (LEqual (Arg0, 0x03), LEqual (Arg1, One)))
                {
                    SPIN (0x96, Zero)
                    WRAM (0x0520, 0x97)
                    WRAM (0x052B, 0x9E)
                    WRAM (0x0520, 0x95)
                    WRAM (0x03A4, Zero)
                    WRAM (0x03A5, Zero)
                }
            }

Should be:

            Method (_REG, 2, NotSerialized)  // _REG: Region Availability
            {
                If (LEqual (Arg0, 0x03))
                {
                    Store (Arg1, ECFL)
                }

                If (LAnd (LEqual (Arg0, 0x03), LEqual (Arg1, One)))
                {
                    SPIN (0x96, Zero)
                    Store (\_SB.PCI0.LPCB.EC0.RRAM (0x0521), Local0)
                    And (Local0, 0xCF, Local0)
                    \_SB.PCI0.LPCB.EC0.WRAM (0x0521, Local0)
                    \_SB.PCI0.LPCB.EC0.WRAM (0x0520, 0x95)
                    \_SB.PCI0.LPCB.EC0.WRAM (0x03A4, Zero)
                    \_SB.PCI0.LPCB.EC0.WRAM (0x03A5, Zero)
                }
            }

Now Nvidia is not present, thank you . But sleep doesn't work. Screen just turns off and nothing happens.

Sleep is off-topic. Open a separate thread.

Your DSDT is not patched correctly (for example, you applied the PNOT patch, which is not correct... at that point, I stopped looking for mistakes, as it is a major one).

I have an Asus N551JB, that's not willing to cooperate since High Sierra. Getting the window server service.....
I tried patching my DSDT but i'm not entirely sure what i'm missing. I did get it to boot on el capitan and with some universal patch before. Would love a push in the right direction.

AutoMerge=true requires the latest RehabMan Clover build.
All of my fixes are not in the sourceforge Clover.
And _OFF is not patched correctly. It has EC related code that needs to be moved to _REG.

Thanks for the help, I'm able to boot to the installer now, it ended up being me forgetting to save ssdt-8 as an aml file and having to use your clover fork.
I couldn't really use your tool because I wasn't even able to boot to the installer.

Keep in mind this guide is usually done at post-install.
For pre-install, it is easier to do the spoof instead:
