I ordered a replacement power supply from iFixit for my early 2010 Mac Mini (a1347), and installed it. I also replaced the BR2032 battery. It is still not booting. Still not even making the slightest noise or light. Just as before the surgery. Any suggestions?
That isn’t a great sign… did you try an SMC reset? Unplug the power cordWait 15 seconds, then hold the power button for 5 secondsPlug in power cord, wait 5 seconds, and try to boot normally. Otherwise your logic board is probably fried. Or you somehow got two bad PSUs, which seems unlikely.
