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.
