XPS 9700 - dGPU won't go off/sleep

[Mrgeque]

Appears to be a variant of UHD 630, I'm using platform id 0500A53E + SMBIOS iMac19,1 with a bunch of framebuffer patches to get my internal screen working + dual 4k monitors @60 Hz over display port.

I think may be causing you issue. this is a laptop? if so, don't think you should be using an iMac smbios. start with changing the smbios and finding something that fits the hardware you have

That's not the issue, thanks though.

Catalina on Dell XPS 9500 (year 2020 model) (OpenCore)

I've created a repository on GitHub to share my progress with getting Catalina to run on Dell XPS 9500. It is almost fully working for me but there may be several other things I haven't tested, including HDMI video/audio output. Any help on fixing the outstanding issues appreciated - headphones...

I think I got it to turn off. If someone wants to use my SSDT (it's modified, not the exact version on Dortania) and see how it works for you, please report back. If anyone has any improvements to build on this, I'm all ears.

Strange, I have an 9700 as well, at least here, no special SSDT needed. Sleep is working fine.

It's a powerful, loud machine, with a stunning display but the sound is not working here neither.

Are you saying you are getting the dGPU to shut off with the regular SSDT? It's not loud when I'm using it for basic tasks - are your fans running a lot? Mine are generally off.

Sleep is broken for me, did you do anything to get it working?

Very likely you need to turn dGPU ON before sleep and then again OFF after wake. Search for DGPU OFF Rehabman in this forum for ideas.

Here's my EFI, try it out. If it works just replace the serial placeholders. I would actually need to clean it up a little but it works OK, so I don't care.

Actually Bluetooth is broken.

Back to topic, Whatevergreen deactivates the DGPU, there is a simple parameter you need: disable-external-gpu / Data / 01000000.

That's it.

Hey, thanks for uploading. The WEG flag doesn't seem to effectively disable the dGPU as I'm seeing much higher power draw if I only use that flag and not my SSDT. Are you running on AC power so you haven't noticed that?

Which sleep/hibernation mode do you have set up? You're able to sleep for 5+ minutes and wake up properly?
Did you change any BIOS variables?
