Mac Mini Power Light Blinks Once

Mac mini power light blinks once.

Soon and will have it serviced there. On mac mini models from 2018 the sil turns off when the computer is fully shut down. During the few seconds of shutdown but before power is removed from the main logic board the sil remains on and will not blink. The only sign of life is the blinking light that.

When it happens like that the power on and of too won t work unless i switch the main socket off. When the display turns off the sil turns on. My imac does not turn on not even make the noise when booting up. Machine starts 20 50 minutes later.

I hope this helps. Macbook pro mac os x 10 6 8 view 1 replies view related intel mac. Mac mini but after a while it won t boot at all. When the computer is fully shut down the sil turns off.
