    Hi Guys,

    im Stefan from Germany and i have a really big problem with my mac mini.

    Everthing works fine, but the front LED is off and the Fans runs always at high speed.
    I found many other people have the same, the only mention is to flash the SMC manually.

    But there is the Problem.
    I installed rEfit.
    Than goes in the shell.
    Type smcflasher.efi -LoadApp m40.smc

    But it returns:

    "Warning you are not in the AppCode mode, but in "U" mode,
    to enter in AppCode mode run SmcUtil.efi with the "-reset 1" option.

    But i dont find the SmcUtil.efi in the internet.

    Have you guys any idea how i can fix this?

    Ah ups i forgot:
    I have all resets done!
    NVRAM
    SMC
    New Battery
    etc



    Sorry for my English, hope you understand me

    Greets Stefan

    Make sure you have the correct 110w power adaptor and not a G4 85w. I accidentally used the 85w on mine, and it caused the fan to run full blast and the front led was off. Everything else worked fine.

    I bought a new one...
    But the problem still exists
    I don't think it can be the power brick as I can get the mini to start up by holding down the power button whilst plugging it in. This is the incorrect SMC reset procedure and I get fans runnning top speed and no LED light.

    Does anybody have a schematic for this mini?

    I press the on/off button, nothing appears, but
    when i holding down the on/off button while plugging the power it in then it goes. This is the incorrect SMC reset procedure and I get fans running top speed and no LED light.

    So in the next Step i found a dead Mosfet, near the Power Input.
    But the Problem still exists.

    But it must be a very small Problem, like a capacitor or else.

    Does anybody have a schematic for this board or have any other ideas what the problem is
