Thanks for your thoughts. I'm pretty sure the little extra bit i was referring too isn't the modem, as the modem i pulled off my 800mhz board was a lot bigger and located next to the RJ11 jack. This one is A LOT smaller (smaller than my pinky fingernail!). There's also another little offshoot at the very front of the board approximately a little bit to the left of where the latch would be. It's even smaller than the previous mystery board, and i think it's the little light that glows when the computer's asleep.

Any chance that the board not booting could be a result of some weird powersupply issue? It's also quite possible that the board's just dead in general. frown

Thanks again
