[Solved] Dell Latitude E6530: randomly freezes when put to sleep/wake up under Big Sur/OpenCore

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)

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
