Time to whip out the multi-meter and check a few things:

- Check to make sure the jack on the motherboard where the power supply plugs in isn't loose, check the solder joints on the bottom with the meter to make sure that power is making it to the motherboard through the jack.
- Check to make sure the power button is good using the continuity test on your meter.
- I am not super familiar with the 2200, but it would stand to reason that there is some sort of +5V "power good" from the power supply, or some sort of secondary supply in the case. Make sure that it is present at all times when the unit is plugged in.

Just a few things that I would check right off the bat. Let us know what you find.
