I picked up a cheap MDD locally, and am having a few problems with it that I'm hoping the folks here might be able to guide me on: This is an MDD 2003-the one released after the PM G5-with a single 1.25ghz. 1. The startup chime from the internal speaker-as best as I can describe it-sounds like a fart. It sounds fine via external speakers, and all other sounds that I play through the internal speakers sound fine(although I haven't tried music or anything else that would really tax it). 2. Probably more concerning(rather than annoying)-when I shut down the computer, it will seem "dead" until I unplug it and plug it back in. It will then work immediately. I've tried a PMU and PRAM reset, and it's still doing the same thing.
