first off hi to everyone i'm new to the forum. well I got a 2008 unibody macbook and it stopped working and the light on the charger does not come on. so I opened the computer up and looked around. I did not see anything that looked bad but when I put my hand on the motherboard I got burnt on a chip. now my question is what is this chip? it says 8904c-f delta 0913 its a little black chip near the power jack. and does this sound like whats causing my problem?
