HD 630 KABY LAKE - SLEEP / WAKE ERROR - BIG SUR

I have same problem.

It seems possible to enter sleep mode.

However, when the computer wakes up from sleep, the screen goes blank and after a few seconds the computer automatically reboots.

 

But, the interesting thing is that when the SMBus controller is loaded, there is no reboot problem and the screen comes on well.

 

When SSDT-SBUS-MCHC.aml is loaded, the screen comes on well when the computer wakes up after entering sleep, but the cooler fan does not turn off even after entering sleep.

@shl628So have you solved the problem yet?

 

No, I haven't solved it yet.

 

I have read through the Sleep Fix in the OpenCore Post Install Guide and tried all of them, but the waking issue is not resolved.

https://dortania.github.io/OpenCore-Post-Install/universal/sleep.html

 

And, Hibernation via HibernationFixup.kext (Hibernatemode 25 & 3) didn't work either.

 

So, I'm currently using the sleep feature with disabled.

sudo pmset -a disablesleep 1
