Other users have had problems with the Fenvi FV-T919 WiFi/BT card, try sleep with this card removed.
Well... this was interesting. I removed the Fenvi and sleep worked... the first time I tested it. Though the fans never fully shut off, it acted like it was sleeping. I put the case back together and sleep never worked again. No matter what I tried, it would always just shut down. So, I decided to rebuild the EFI from scratch (keeping the same serial numbers). I still left the Fenvi card out. I booted the BIOS and rebuilt the settings, then proceed to Mac boot with the "new" EFI. No difference except... now there is no entity (BIOS or Opencore) that can see my windows SSD to boot from it. The BIOS can see the disk, just not enough to see the boot files. What could have caused this?? I should have known better than to start this before the weekend. Oh, the NZXT controller has been disconnected the whole time.
I guess I'll try doing a fresh install this weekend on a spare drive and see if sleep starts to work then. BTW, does it matter what fan profile I set in the BIOS? Or does the MacOS always do its own thing after booting?
Thanks for the advice so far. I'll let everyone know how it goes.
1. saw someone chose at setup iMac 20,1 vs per tutorial iMac19,1. Should I have done the same with my setup. Was there any benefit in choosing a newer iMac vs?
Hey,I built mine in a H710i and used the NZXT controller for the case fans. It never affected sleep/wake for me. Only the Fenvi card cause sleep/wake issues which I eventually replaced with a Youbo. So it may not be the controller.
