Dell N3459 - HD520 - HDMI Video issue

[RehabMan]

Dear RehabMan. I think finally my sleep problem may be fixed, It took me several hours to find out what is Intel MEI in my ioreg and I also found out that Device IMEI is not existed in my DSDT. So I used "Add IMEI" patch, then IMEI shows up in my ioreg from now. I will make more tests to make sure everything is alright.

config.plist/ACPI/SSDT/Fixe/AddIMEI=true is a valid way to fix your issue.

I have another question about patching IMEI. First time, I was going to use hotpatch with SSDT-IMEI. I read your comment

// need the device-id from PCI_config to inject correct properties"

But I don't know how to find device-id from PCI_config, I read other threads saying that I can find it from using

lspci -nn

in linux (Image attched). I tried that but having no clue how to detect it. I hope you can give me some hints or any useful guild, instructions, ect. Thank you so much.

The comment is explaining what the code is doing.
