I thought the initial motherboard replacement may have been the issue but I swapped it out another with no results. I can't VGA out the system to a monitor either (which would suggest a problem with the video card, but I figure I'd at least have power to the screen.) I'm at the point where I don't so much care about having mobile computing abilities, but more obsessed with figuring out what I'm missing here.
Before this abruptly shut down, was this laptop getting hot underneath ?
Did you feel any hot air from the air vent ?
You said you checked everything but have you looked into a cpu over heating problem ?
Also have you thought about the power supply on the mobo maybe faulty ?
Check into those again abit more closely once you find the culprit.
Come back here and let me know I'll see about getting you a replacement part with instructions to do it right.
