You said you tried mayer's advice in the other thread suggesting to check the pins on the power adapter for being loose? Have you tried another power supply? I know when I brought mine into the Apple store they used theirs so that threw me off. I still don't understand how my issue appeared to be power related when, like you, I was still able to get a solid green light and charge my battery. When I started to test each piece connected to the logic board I started getting funny responses from the adapter. It would be feint green at times, when I'd trip the power pads, it would blink orange, sometimes it was solid green. I would disconnect the whole I/O board and then reconnect it to make sure all the connections are good. I feel like mine might have been loose somewhere. Hold the adapter to the port physically to make sure its connecting properly. It seems like its getting power initially but theres a weak connection somewhere.
