avdo Posted September 2, 2017 Share Posted September 2, 2017 Hello all, I'm stuck and not sure how to tackle disabling my discrete Nvidia Quadro card. A quick search of my disassembled ACPI tables show that their is only 1 SSDT related to GPU but has no methods to disable card. DSDT has _INI , _OFF, and _PS3. I have no idea what the correct way I have included extracted ACPI tables, Kextstat & Kextcache Terminal Outputs and IOregistryExplorer snapshot & /EFI/Clover folder. My DSDT has been patched & everything is working well. I only need to be able to disable Nvidia to have 100% working system for me as it's a pain to re-enable Nvidia in BIOS when dual booting to Win7. Any advice would be greatly, greatly appreciated. EDIT: Finally got this sorted with some clarification from Rehabman (thanks!). Scope (_SB){Method (_INI, 0, NotSerialized) // _INI: Initialize{^PCI0.PEG.GFX0._DSM (ToUUID ("a486d8f8-0bda-471b-a72b-6042a6b5bee0"), 0x0100, 0x1A, Buffer (0x04){0x01, 0x00, 0x00, 0x03 })If (One){^PCI0.PEG.GFX0._PS3 ()} Sweet thermals and quadro functional when booting into Win7. Result. Link to comment Share on other sites More sharing options...
