Weird Shuttle problem

So my fiancee's Shuttle system (that I built for her about three years ago) is having this strange problem. If you push the power button, absolutely nothing happens. Then about two minutes later, the computer turns on and starts booting.
Any ideas?
ps-completely unrelated, does anyone know of an online company that makes custom device cases? I need a case for my MP3 player and can't find one the right size/design.

Is the physical button "sticky"? Perhaps the contact (or button cap) is sticking or binding on something and it just takes time for it to release.

There's a fella on the mp3car forums whose handle is VeritasForge. He does custom cases for the folks there and does a pretty decent job (check out the one in the thread I linked.) He generally works with steel, not aluminum, but he may be able to do aluminum too.
Another example.
Wait a minute...are we talking about computer cases or like a soft carrying case?

There's a place in Monterey where I grew up that makes custom wetsuits for scuba diving. Last time I was in there they had a large sign that said something to the effect of "no, we won't make you a neoprene case for ..." Not really helpfull advice, but it seemed relevant.

I'll check that out, it's an interesting idea. I'll see if it's even something that's fixable (I don't know if I'll be able to get into the button its self). Quote:

Yeah, sorry, I'm talking about "small" leather cases. I need something that I can carry my MP3 player in. I'm basically looking for soft, thin leather, a belt clip, vertically oriented, no velcro, and it has to fit something with the dimensions of 5.2"x3.1"x.75". It doesn't even have to have holes for headphones. I've looked all over and can't find anything like this, and I can't seem to find any companies that make things like this.

I got a case for my Ipaq hx4700 from Sena and I love it. They make cases for cell phone, pda's, MP3 players, etc..

Neat! They have a great selection. I think I remember them from when I was looking for an Axim case, and I was thinking about going with theirs. Maybe if I contact them with the dimensions I need, they'll be able to point me towards a case that will work...
Thanks!

I've seen this too, actually - both on my shuttle and a friend's one. The switch is working fine, it's just the PSU seems to have a crisis - just when you think it's toast, it comes on and works fine as if nothing was up.
Not really looked into it much as, well, it works (and my shuttle is my single permanently-on box, doing my Skype USB phone & X10 control amongst other things)

Interesting! It seems to be more of a Shuttle-specific problem then. You don't happen to have this one too, do you?

Not sure what one it was, except it was an Intel one. I guess the PSU would be the same though.

Have a quick look at the PC motherboard inside the shuttle. I've had two where the capacitors leaked and they both acted really strangely. Odd crashes and sometimes it just wouldn't even power on.

Have you had any more experiences with this? The computer in question has been doing this ever since I posted this thread. For a while, the amount of time it took to power on had shortened, but then it went up to about 10-15 minutes, and tonight it doesn't look like it wants to power on at all 
Has anyone heard about something like this, or have a fix?
This sounds a lot like problems we had with about 30 Dell Optiplexes. Motherboards would slowly fail due to bad/leaking caps, but they managed to take the PSUs with them. PSUs would start failing to where they wouldn't start up
Try this experiment: Before trying to start computer, completely unplug it from AC power and count to 30. We have had a dozen Dells that would refuse to start -- would not respond to the ATX-->PSU signal, but they *would* start if we depowered long enough (to drain caps in the PSU, maybe??)

I'll try that the next time I need to boot it. For now we're just leaving the machine on, and I've ordered a replacement PSU.
One odd thing I noticed: from a state where the computer was completely unplugged, I could plug it in, wait a couple seconds, and if I then held the power button on the front for about five seconds, the little light on the bluetooth keyboard receiver would light up. It would light for about 10 seconds, then go off. About 15 minutes later the computer booted...

That sounds vaguely like ASUS motherboard behaviour. Ugh!

Have you actually looked at the capacitors?

They all looked fine to me, but I'm not sure if my untrained eye would be able to tell anyway. Still, they appeared to be ok.

Usually the top will be bulging or split. The rubber plug on the bottom may have partially come out as well. Its fairly obvious when you see them.
Do you have a spare PSU lying around that you can plug in? You don't have to mount it so it can be a regular sized PSU.

I don't, but I have a replacement on order anyway, so I'll see what happens when that comes.

FWIW, of the 30 or so failing Dell mobos we just swapped, about half had caps that could be seen to be failing (with bulging, leaking). The other half looked fine, but the boards crapped out nonetheless. So it seems like bad formulation/electrolyte doesn't always result iin a visible problem. And we had one Dell tier-one tech tell us "because it ain't leaking it must be OK and I can't dispatch a swap". Wrong.
Funny, it took a while to find all of these. We'd ask people "Is your Dell working OK?" they'd say "Oh, yeah!'. But then we'd push a few more questions and they'd finally say something like "Well, come to think of it, it does turn itself off occasionally! is that normal???"

Well, actually that is normal. Energy Star power savings and all of that.

Sorry to quote myself, but the replacement came, and in case anyone is interested, it solved the problem. Looks like it had everything to do with a bad PSU, though the behavior was quite odd. You'd think it would either work or fail outright. Regardless, the Shuttle is as good as new.
