Thanks for your help. I'll stick to boot arg solution. Problem is solved.

I'm using Clover. I think the problem dGPU is disabled when i reboot Mac OS. I don't know how to enable it while rebooting. If i use only -wegnoegpu boot arg (disabling patches and SSDT-DGPU) Nvidia card is present in Device manager.

Hi! I'm having a problem with DGPU. It's disabled using SSDT and ACPI patching. The issue is: After reboot from MacOS into Windows Nvidia NVS 5200m is not present in Device Manager. How to fix the problem? Specs: Dell Latitude E6530 with A22 Bios i7-3740QM 1366x768 screen 16GB RAM HD 4000 + NVS 5200M(disabled in SSDT-DGPU) Mojave 10.14.6 EFI.rar

After some additional testing this method also didn't help solving this issue

It seems switching Serial Port to COM2 and using original DSDT without any patches solves the problem.

I am using modified Herve's EFI and everything works fine except this problem: Sometimes there is no sound. Sleep/Wake or Reboot helps to restore sound. Tried everything, but the problem persists. Lilu+AppleALC debug report and EFI(ACPI, config, kexts) attached. Specs: Dell Latitude E6530 with A22 Bios i7-3740QM 1366x768 screen 16GB RAM HD 4000 + NVS 5200M(disabled in SSDT-DGPU) Monterey 12.7.3 report.zip EFI.rar

Problem solved by switching to Monterey

The laptop almost perfectly runs Big Sur, but i experienced this annoying issue: From time to time display goes dark following the apple logo on boot, and then the machine goes to sleep. After i wake it from sleep by pressing the power button, everything works fine. I used Herve's E6230 EFI folder( attached it), also used my own patched DSDT and SSDTs. Nothing helps to solve this problem.

I've switched to Clover and the problem is gone. Thanks everyone for your help!

Switched to Mojave with the same setup(OpenCore). Still have the same issue. I will try to generate a bug report now debug_20341.zip

Problem still persits. Two things to mention: 1. I had a wrong SSDT-PM(replaced it - didn't fix the issue) I guess something is wrong with SSDT-PM. 2. SSDT-EC doesn't replace the name of the embedded controller. ( tried rename ECVD to EC - Failed to detect SuperIO) EFI_14072023.rar It seems with this SSDT-PM I had less problems with freezing after wake. But still have some. Where can i find a fully working SSDT-PM for i7-3740QM? SSDT-PM.aml.zip After few reboots laptop started freezing after wake up more frequently. Also SSDT-1(cpu0lst) compiles lots of syntax errors

Also didn't work

Hi! I replaced all these but it didn't fix the issue.

I've figured out that Sleep working with this DSDT file(E6430,HD4000+NVS5200M). Now I need to find out what caused sleep issues using my original DSDT DSDT_ORIGINAL.zip DSDT_SLEEPWORKS.zip

Can you share your EFI folder for Catalina? It would be very helpful.

I will try to switch to clover. Thank you. Btw, I've managed to get bootlog. May you check it for any issues? bootlog.rar

Hello! I have Dell Latitude E6530 which freezes mostly after wake up(sometimes when I put it to sleep), so I have to manually turn laptop off using a pwr button. Sometimes I can repeat Sleep/Wake Up cycle up to 2-3 times. Another time it hangs after the first wake up. What I tried: hibernation off, Opencore update,disable dGPU via SSDTs(currently using boot-flag -wegnoegpu). I've followed the guide from the FAQ to send debug report but couldn't generate report file(mount: / failed with 66). Also I've noticed that wireless networking indicator starts blinking when system freezes after waking.I link my EFI folder and IOreg logs. i7-3740QM 1366x768 screen 8GB RAM HD 4000 + NVS 5200M System: macOS Big Sur 11.7.8.
