Have you had any luck figuring out what the problem is? I have taken mine down to the motherboard and bench tested with bare necessities, new power connector board, new power button board, new power adapter, one ram......same thing. Didn't bother with an external monitor because the second the power button is turned on, it turns off. The question is does the onboard video card require a external monitor to be attached for the power button switch LED to stay on and a possible boot? Stupid question.....but numerous google searches have not provided an answer.
