Check the PRAM battery. Many of the Mac models with soft power won't boot
without a good PRAM battery. It need not read the full 3.6 volts, but
anything less than 1 volt is no good.
The battery, oddly enough is available as a regular stock item at Radio
Shack (yet similar PC CMOS batteries are not... go figure).
Also, the 550 models are soft power, but also have a hard power switch on
the back. Make sure the switch is on, and then hit the power key on the
keyboard to actually power it up. Just flipping the hard power switch on
the back won't let the mac boot (but will usually result in a quick
electrical pop noise as it charges up, if the mac has been idle long
enough).
