Just got done dismantling my e1505 to try some part swapping. I got my mobo bare (everything removed except processor) and plugged in the power. The power light went on solid and so did the number lock light...the scroll lock and caps lock flashed. It did it for 30 seconds or so before it shut off. I then removed the processor to see what would happen and applying power to it gave me all solid lights for the same amount of time. So, I know how a good mobo should act. Since the other mobo didn't act this way, I can now say for sure its the mobo that is causing problems. I did swap some parts between the two mobos and nothing surprising came out of it. Now that I know for sure its the mobo, I have two options. Break out the heat gun and try to "reflow" it myself...might as well since I have nothing to lose. And then if that doesn't work I'll try find a replacement board.
