Don't think that option is available for this model, just need to disable it with SSDT. Haven't use Clover in year but give this a try. Attached are your modified config file and SSDT to disable the discrete card. Place it in your SSDT/Patched folder You should remove all these kexts as well: All the fakepciid* kexts NullCPUPowermanagement.kext VoodooI2C* IntelGraphics* If you're going to use VirtualSMC, you remove all the FakeSMC* or vise versa Determine what ethernet device it has, you have way too many different kext for it. Only add the kexts for what it has. HD5500.zip

Try this, updated kexts and OC to 0.9.4 Lenovo_P50_OC_0.9.4.zip

Is your display 4K? Can you set DVMT to 128MB? I remember there's a setting in my HP Elitebook with HD520, I can set it but mine is only 1080p display. Under Built-In Device Options in the BIOS set Video memory size 128MB if you can, make sure to disable framebuffer-stolenmem and framebuffer-fbmem in config file

Not according to your IOReg file But now I see you have this in your Config file. Disable it or delete it PciRoot(0x0)/Pci(0x1C,0x0)/Pci(0x0,0x0)

Try disabling the discrete graphics card Unless con0 is connected the the Nvidia See if it can be disable in the Bios

add this SSDT to disable the discrete graphics card SSDT-Disable-DGPU.aml.zip

Post the efi folder + IOreg file using IORegistryExplorer.app

You'll need to add sleep and wake patch

Your USB kext is hardcoded to EHC1 and EHC2 UTBMap.kext one other difference is this \_SB.PCI0.PEG0.VID.MLTF = One to \_SB.PCI0.PEG0.VID.OMPR = One

Differences between the 2 DSDT Rename EHC1 -> EH01 Rename EHC2->EH02 Rename ECDV->EC Rename GFX0->IGPU

Can you post the IOReg file?

What Intel.plist? Attach your EFI folder for review Attach IOReg file using IORegistryExplorer.app v2.1

post your full system specs

Post the KP

What error did you encounter when you sleep or close the lid?

Is there an option in the BIOS to set DVMT to 64MB? if not, then you could patch it by adding to the config file framebuffer-fbmem = 00009000 (data) framebuffer-stolenmem = 00003001 (data)

as far as I know it's only NVMe drive. Sata SSD are fine.

I don't think so...like PM991 See here

replace the hynix drive, not supported

See this comment from Hervé

try switching to layout-id = 77 if still not working, then try 3, 13, or 15

Make sure to reset NVRam after the changes can you post new IOReg file?
