After sleep the laptop screen still isn't coming to life, external HDMI has to be unplugged and re-connected.

I've been using Hackintool to switch to MBP 13,1 but I'm still seeing MPB 13,3

USB ports back with USBPorts_5520.kext with Monterey (Big Sur not seeing them) once I edited the config.plist to look for it.

Using Jake Lo's Precision 5510 O.C. 0.8.5 + USBPorts_5520.kext = HDMI + all USB ports + ethernet (hub) / no screens after wake from sleep with Monterey.

Cherry 5520 IOReg.zip

I have Display Menu installed. Max display = 1920 x 1080

Replace only the usb kext?

usb-c is back with USBPorts_5520.kext 

Should I just accept that 'sleep is not an option'? 

Same troubled-sleep problem with your 5510 (the 0.8.5 version) + I lose the usb-c port.

Currently on Big Sur 11.6.1

Boot-args = debug=0x100 darkwake=1 alcdelay=500 igfxonln=1 -v

Thanks very much for your reply:

I've switched to MBP 13,1 and tried 0x191b0000 and 0x19160000 I have also removed boot-arg agdpmod=vit9696 but my original bug / concern (wake from sleep) is still happening (the internal screen remains black / flickers after sleep).  

sysctl -a | grep brand = Intel(R) Core(TM) i7-6820HQ CPU @ 2.70GHz

All ports currently functioning with 0x191b0000. Jake Lo's un-edited 5520 EFI obviously wasn't compatible with mine however it was able to wake from sleep without issue, so there's hope for me yet...

Thanks for the reply - will do:

I've been running Big Sur and Monterey on a 5520 (Nvidia Quadro M12000) without issue using Jake Lo's 5520 EFI. However now the HDMI ports on the laptop and the dock aren't functioning. Dock and menu bars now have black backgrounds.
