I just purchased a Mini Core Duo with 1Gb ram at the local Apple Store 2 days ago. The fan noise is getting louder, and the white power led is continuously off even when the system is otherwise working fine. Any thoughts on why? Or, is this system DOA?

Thanks,

Doug

    I have both these problems following system overload/freeze. Telephone support told me to take it to an Apple Store. Looks like firmware/BIOS problem to me.

    I've had the same issue too. What I did was turn off the Mini, and I left it unplugged for about 45 seconds. When I plugged it in again and booted it, all was well. I think it's a PRAM issue that is fixed by leaving the Mini unplugged for a few moments.

    I had a Mac Mini Duo which did not start up on first plugging it in.( Bought May1, 06 )
    Resetting the PMU allowed me to start it....but the fan was on all the time,( howling! ) unless the unit was asleep or off.
    Unplugging it or resetting PRAM resulted in the same state as the original: ie it wouldn't start without resetting the PMU.
    After hours of running utilities etc., I took it to the Apple store. They confirmed it was a hardware issue but referred me back to Apple, since they said this was a custom order ( 1GB RAM, 100GB drive ) and they therefore could not replace it.
    After an hour long phone call, I finally got an RMA number after arguing this was a DOA item.
    A bit of a hassle!

    Yes in the end our problematic Mac Mini had to go back because startup became permanently erratic. Then the replacement had the problem with the fan being on all the time ...

    And finally the Apple store mucked up the data transfer. We wasted many hours and unnecessary visits to the shop over all of this. Not impressed!
