Hi Guys, I have a 2009 Macbook Unibody that will not charge. Battery is about 2 years old, computer runs fine. I believe it's the connection on the motherboard, or the piece that connects to the motherboard. Simply put, the magnetic piece that the mag safe connector connects to. I've used two different chargers and neither work. I've had some plastic chip away there and some metal particles attach to the area around the magnetic connector but I cleaned it out to create a firm connection, still no dice. Any chance I can replace this part?
