My laptop is Acer V3-771g . 

I added only one line \_SB.PCI0.PEG0.PEGP._OFF () in the beginning of _INI under IGPU in SSDT , then the gt630m was disabled . But the laptop goes shutdown when it is restarted . After awoken from sleeping , the laptop can restart normally .

 

Adding _ON() in _PTS is of no use . I guess _ON() must be added in some where i don't know .

Can you help me to disabling nvidia card? i've done step by step carefully but i still have my nvidia card running. My laptop is Dell Vostro 5460 with Intel HD4000 and NVIDIA GT630M graphics. I attach my DSDT and my config.plist file also, i suspect if anything wrong in my config.plist but i have no idea what it is because i'm new in hackintosh. Thanks in advance.

I wish to share my experience.

Dell Latitude E6430 has Intel+Nvidia Optimus and Intel can be switched off in BIOS (Optimus = disable, yeah, it switched off Intel) so Nvidia will be only videocard.

So i want to have DSDT and SSDT to be universal and working in both cases.

ACPI has simple check if ClassCode of Intel is 0x0300.

_PTS method

        	If (\_SB_.PCI0.IGPU.DCLS == 0x0300)
        	{
    			\_SB_.PCI0.PEG0.VID._ON()
		} Else {
        		\_SB.PCI0.PEG0.VID._OFF ()
		}

_WAK method

        \_SB.PCI0.PEG0.VID._ON ()

        If (\_SB_.PCI0.IGPU.DCLS == 0x0300)
        {
		\_SB_.PCI0.PEG0.VID._OFF()
	}

Comment: we need Nvidia to be working after wake if it is only card.

With this DSDT I have working sleep/wake/shutdown in both BIOS config.

 

Method _INI in the SSDT

           If (\_SB_.PCI0.IGPU.DCLS == 0x0300)
           {
              \_SB.PCI0.PEG0.VID._PS3 ()
           }

Guys, I'm having problems with my new laptop, Acer Aspire A515-51G-70PU.

It has the NVIDIA Optimus 940MX and I've tried everything to disable it. I'm stuck at the installer boot, It hangs on "Service only ran for 0 seconds".

I'm sure it's a discrete graphics card issue... Attached are my DSDT and SSDT files that I extracted using Clover. Please, help me!

Just finish editing the optimus 520m to off. and i don't need to remove geforce kext anymore also with skipnvidiagfx=yes in org.chameleon.boot.plist

 

question..

Do i really need to put m_On in PTS method?

 

 

  


    Method (M_ON, 0, NotSerialized)
    {
        If (CondRefOf (\_SB.PCI0.PEG0.GFX0._ON))
        {
            \_SB.PCI0.PEG0.GFX0._ON ()
        }

        If (CondRefOf (\_SB.PCI0.PEG0.GFX0._PS0))
        {
            \_SB.PCI0.PEG0.GFX0._PS0 ()
        }
    }

    Method (_PTS, 1, NotSerialized)  // _PTS: Prepare To Sleep
    {
       

       // M_ON()     // ...................Needed or not

        If (LNotEqual (Arg0, 0x05))
        {
            PTS (Arg0)
        }
    }

        Method (M_OF, 0, NotSerialized)
    {
        If (CondRefOf (\_SB.PCI0.PEG0.GFX0._OFF))
        {
            \_SB.PCI0.PEG0.GFX0._OFF ()
        }

        If (CondRefOf (\_SB.PCI0.PEG0.GFX0._PS3))
        {
            \_SB.PCI0.PEG0.GFX0._PS3 ()                  // no SGOF 
        }
    }

    Method (_WAK, 1, Serialized)  // _WAK: Wake
    {
        M_OF ()                           // shutdown in wake
        If (LOr (LLess (Arg0, One), LGreater (Arg0, 0x05)))
        {
            Store (0x03, Arg0)
        }

        WAK (Arg0)
        Return (Package (0x02)
        {
            Zero, 
            Zero
        })
    }

 

 

....

....

   Scope (_SB.PCI0)
    {
        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            M_OF ()  // Shut down when initialize computer
            Store (0x07D0, OSYS)
            If (CondRefOf (\_OSI, Local0))
            {
                If (LOr (_OSI ("Darwin"), _OSI ("Linux")))
                {
                    Store (0x03E8, OSYS)

 

....

Is there anyway to get some help with disabling my laptop 950m Nvidia on my laptop?

 

MSI GP70 2QF Leopard Pro 486

core i7-4720hq Haswell

Intel HD4600 graphics 

Intel HM86

16gb DDR3

 

Attached is ACPI file which I was able to extract using F4 at the clover boot up screen.

 

Have Mojave installed but with the Optimus still enabled my battery dies out pretty quick. Hoping to get this fixed so it will at least last longer.

 

Thanks for any help.

I am using only DSDT on my E6420. Can it be done with DSDT only?

 

Best regards.
