Fan starts for one second then it turns off
my mac mini starts by its own when I plug it into power and then it keeps starting up fan spins for a second and the led light turn on for a second at the same time . I check the power supply output voltage and it is 14.8 V on four pins and 0V on four pins and one goes from 0.9 to 2.6V when the fan spinnes. I alredy checked the power button and tried to start it with only power supply pluged but it is the same I checked the logic board and it looks in good condition. Hope to find the answer?
Is this a good question?
