Mac mini: Fan on full speed + front LED off ?!

[Ancandis]

After resetting my Mac mini with the PMU reset it

- runs its fan on full speed
- the front (power) LED does not show anything
- SMC fan control shows "0°C" / "000rpm"


Any way how to fix that? I did a PRAM and PMU reset again, but no go. Thanks.

Have you recently had the Mini opened up? Sounds like a connector is off.

No, it has never been opened. The only thing I did was the PMU reset (unplugged all cables for 10 sec. and plugged the mains cable while holding the power button).

Newer Mac don't have PMU if I remember correctly.

You may have damaged your Mini by doing this.

Try unplugging it again, but don't hold the button in this time when you plug it back in.

Actually even two Apple Care employees told me to do so.
