2013 Mac Pro No Power
I have a 2013 Mac Pro that won’t power on.
Customer reported that the system had randomly powered off by itself a few times before it finally wouldn’t power on any more.
Currently when power button is pressed there are no lights, no clicks, nothing. I already tried an SMC reset and replaced the CMOS battery, not because I thought they would work, but mostly to check the boxes and hope for a lucky break.
At this point I’m pretty sure it’s either the logic board or power supply, with my gut saying it’s probably the power supply. Unfortunately I don’t have spare parts to test with to confirm which is faulty. Is there any way to test voltages on the power supply to determine if the power supply is dead or short pins to power it on?
Это хороший вопрос?
