Here is my problem. I have two xbox's and both of them for some reason wont power on. I at first thought that it could be the power supply but I then tried a working power supply (3rd xbox) and both still did not power on. I then was wondering if the power/eject button wasnt connecting or maybe they were both bad. I then put my working eject/power button (3rd Xbox) on both with my working power supply and once again nothing. I was wondering what could be causing this problem and what maybe traces on the motherboard are for power. One xbox just one day wouldnt power on (No reason why). The other xbox I tried putting a screw in and I think I scratched the mother board around the right side. If anyone wants me to I can post pictures as soon as I get homem which will be around 3PM EST.
