That explains it, it's a known issue with that type of power supply connection - Glad you tracked it down.Hi P1lgrim,
you've been of great help, thanks to you I managed to fix the shutdown issue and as part of the attemps to solve the sleep mode problem I also generated the SSDT for power management which, I think, will optimize the CPU performances.
As for the sleep mode issue, it turned out that it was due to my power supply (Corsair RM 850i) that has a data cable (to monitor its status) connected to an internal USB socket of the mobo. If I disconnect that cable, sleep mode works well.
