The USB-plugging issues were on  Qt_Extended_4.4.3, I believe. The powerup out of nothing was Android panicking v17 latest noncupcake jiffs2. As far as just holding it and it shutting off, is it possible the acclerometers are doing something?

Regarding powering off out of nothing. I thought that if it was off, it was OFF. Is there some level of processing still running?
