I had the same problem TWICE! After shutdown my mac mini, it just won’t turn on. I took it to genius bar, they changed the motherboard to fix it finally. I don’t think the motherboard was totally broken but some chips may too fragile to keep the system up for a very long time. I mean months. For data in your system, because SSD was soldered on chip, A Time machine is A MUST!
