disable NVIDIA GTX 1050ti MSI GL62M 7REX

[maxleo]

Hello to all, 

It has been more than 2 days since I try to modify my DSDT to deactivate the discrete graphic of my laptop PC.

It is about a MSI GL62M 7REX with two graphics boards:
Intel HD630 and GTX1050ti...

After numerous tries, my laptop does not start because of my GTX 1050ti which it is necessary to deactivate in the DSDT.

Would it be possible to have some lights on my DSDT? 
I join the DSDT.aml 



Thank you for your help, cordially

check ur ioreg and disable only correct device

u dont need disable 7 devices, u need disable only one

RP01.PXSX, RP05.PXSX, devices is used for USB, THUNDERBOLT

Use this SSDT only in install after it, check ur ioreg and disable

Device (HACK)
    {
        Name (_HID, "HACK0000")  // _HID: Hardware ID
        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            If (CondRefOf (\_SB.PCI0.PEG0.PEGP._OFF))
            {
                \_SB.PCI0.PEG0.PEGP._OFF ()
            }

            If (CondRefOf (\_SB.PCI0.PEGR.GFX0._OFF))
            {
                \_SB.PCI0.PEGR.GFX0._OFF ()
            }

            If (CondRefOf (\_SB.PCI0.PEGP.DGFX._OFF))
            {
                \_SB.PCI0.PEGP.DGFX._OFF ()
            }

            If (CondRefOf (\_SB.PCI0.RP01.PEGP._OFF))
            {
                \_SB.PCI0.RP01.PEGP._OFF ()
            }

            If (CondRefOf (\_SB.PCI0.RP01.PXSX._OFF))
            {
                \_SB.PCI0.RP01.PXSX._OFF ()
            }

            If (CondRefOf (\_SB.PCI0.RP05.PEGP._OFF))
            {
                \_SB.PCI0.RP05.PEGP._OFF ()
            }

            If (CondRefOf (\_SB.PCI0.RP05.PXSX._OFF))
            {
                \_SB.PCI0.RP05.PXSX._OFF ()
            }
        }
    }

disable only one and correct device, e.g PEG0/PEGP(common video device)

Device (HACK)
    {
        Name (_HID, "HACK0000")  // _HID: Hardware ID
        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            If (CondRefOf (\_SB.PCI0.PEG0.PEGP._OFF))
            {
                \_SB.PCI0.PEG0.PEGP._OFF ()
            }
        }
    }

Example

check here, inside RP05/PXSX, not a video

[MARZILLO]

this  ssdt is good for nvidia and amd

[MaLd0n]

good is disable only correct device not 7

 

for install is good, but after install check correct video device and disable only it

Well, i follow your precious advices.

I use the _off méthod for only one device, with windows I determine that the 1050ti is peg0-pegp. Then the DSdt works fine!

Thanks for your help!
