That all sounds logical, Andy, and I would have put that on my list of
things to do next had not a different solution apparently came about. I
****fted the MacMini when I needed to connect it to a 46" HD TV and
discovered there was a fair bit of fluff and dust and stuff round its
fan intake, so gave it a thorough vacuum and clean. What I think was
happening with the unusually warm weather we were having, and the fact
that it was in a fairly airless spot, was that it was overheating and
was wanting to fan itself more to get to a lower temp before actually
turning off completely. (I think it 'forgets' to turn off actually in
that case). My pressing the button after a few minutes apparently meant
that it interfered with the morning startup. It worked fine last night
shutting down and this morning starting up.
So it appears that if they overheat a bit, they don't like it. This
might be helpful to others if they find the same thing happening. Vacuum
them down!
I did wonder about a flat battery but that surely wouldn't have stopped
it shutting down properly.
(Incidentally, have you ever seen what they look like on a huge HD
screen? - fantastic!)
