Hey guys,

My specs are:
MOBO: P8z77-v pro
CPU: i7-3770k
GPU: RX560
OS: Catalina 10.15.4

Another aren't matter although listed specs too.

My issue was in following. When I manually tap "Sleep" from Apple menu, monitors turns off, but fans spinning and lights are on forever. So hack won't go to sleep. Couple days ago I updated from 10.15.2 (where all worked fine) to 10.15.4. So I thought that the problem appears after os update. I tried to reset cmos, reinstall bios, play with darkwake, update lilu, whatevergreen, remake ssdt-USB, DSDT and all other actions which make success sleep. Nothing works.

I've spent 2 days with nothing. I decided that the second day is the last. I'll make it sleep or reinstall OS. And by the end of second day I remembered that immediately after update mac ask to update Epson driver (for my Epson M105, name: EpsonUSBPrintClass.kext v.2.2.7 creation date 09/29/16). Kext was installed in /L/E. After I deleted it and repaired permissions and tap "Sleep" my hack finally went to sleep.

Hope my story will save time to somebody.

Thanks.
