Electrolytic capacitors dry out.

It's been a while with Suns for me. I assume the power button is a soft 
button and not a hard switch. If this is the case perhaps the power 
supply's ability to provide the power to the circuitry for the soft power 
on is dead.

There are instructions for the capacitors that go bad on SGI Indigo2 power 
supplies floating around out there. I'd imagine a similar thing is going 
to happen to all of these older systems soon enough.
