Mac Mini dead. Fan just keeps quarter spinning ‘pulsing’

Текст:

Hi. Just wondering if anyone knew what might be the issue here. PSU is fine so it looks to be a logic board issue, but I’m not sure if it’s something than could be fixed.

When I attach the power cord, the fan does a quick spin then stops, then a quick spin again, then stops, and it just keeps doing this. This is without touching the power button. It’s looks like something is failing even before it can be in a state to be turned on.

There are some places that do logic board repairs, but maybe someone has an idea what the issue may be, as I’m a little concerned leaving my Mac mini with someone for several days with 2 drives full of all my personal stuff.

It’s a Mac Mini Late 2012 2.6GHz i7 (A1347)

Thank you,

Keith

Someone had a look, but can’t do repairs at a logic board level. Initial diagnosis, “Sadly it is the logic board and not the power supply. I don’t have a schematic for the board so can’t confirm the issue but one-wire communication for power on is working but the processor is not providing the start-up logic.”
