I've gone through four power supplies, two non-approved and two 750W Antec (on the approved list) power supplies.
Neither of my two CM4 boards give any glimmer of powering on. PSU fan doesn't spin, no lights on the board. Worked with them on an anti-static mat. 3.3V is stable as well. I've checked my CR2032 batteries to make sure they were good as well. I've tested the power supplies without the CM4 and it works fine. I'm using an SSD plugged into the first sata port incase it needed that for booting. I'm totally out of ideas. Anybody have any ideas on what I can try?
