Sorry I didn't attached my files because I hadn't a problem but was just asking for a tips.

I used the tool provided by black.dragon74 this time, hope it will be fine.

Note this setting in your config.plist is very wrong:
config.plist/SMBIOS/ProductName="MacBook Pro 13,3 2017"

Your ACPI configuration is bugged, due to using an incorrect Clover.
Must use my latest build of Clover for working AutoMerge=true.

Yes, I forgot to correct this one.

I download your latest version of Clover here and reinstalled it.

Concerning my original question about knowing if your discrete graphic card is disabled, can I find this information somewhere on my laptop?

Thank you!

Once we have a working scenario and a non-working scenario (already have one), I'll show you the difference in ioreg.

What is confusing?
_OFF is in SSDT-6. It calls PGOF in SSDT-3.
No associated _INI, so you can simply add one to SSDT-6, right before _OFF (or after):

Method(_INI) { _OFF() }

so just adding that line will disable the dedicated graphics for me?

Likely. All code must be tested, as predicting the future is impossible.

Hello,

I'm using Asus A455LN with Intel HD 4400 and NVIDIA GT840M, After following your guide and disabling the NVIDIA Card via DSDT/SSDT Edit as guided at #1 , however i still see NVDIA GPU on the System Report, but it's not available on the DPCIManager, also it still exist on IOReg on RP05.

is there anything wrong with my DSDT/SSDT Edit? thanks!

Your ACPI configuration is wrong:
- dynamic SSDTs should not be in ACPI/patched (remove SSDT-x*.aml from ACPI/patched)
- config.plist/ACPI/AutoMerge should be true
- Clover needs to be updated to my latest build
- you need to remove most (if not all) config.plist/ACPI/DSDT/Fixes (most that you have are not recommended/not needed/wrong)
- if you were to do renames (GFX0->IGPU, B0D3->HDAU) via config.plist/ACPI/DSDT/Patches (see my Clover laptop guide plists for common patches), you could remove the following files from ACPI/patched: SSDT-0-zpoddult.aml, SSDT-1-Cpu0Ist.aml, SSDT-2-CpuPm.aml, SSDT-3-DptfTabl.aml, SSDT-4-SataTabl.aml, SSDT-5-SaSsdt.aml, SSDT-7-CppcTabl.aml, SSDT-8-Cpc_Tabl.aml, SSDT-9-OptTabl.aml), leaving the only patched SSDT: SSDT-6-SgPch.aml

I've got a Lenovo Yoga 720 and am trying to disable Nvidia. The off method and INI are located in SDST 10. I don't see any EC code there and have added the patch to the INI but it isn't working. Rehabman, can you take a look?
