My Macbook Pro 2009 woke up today with a broken trackpad. Up to today I havent had a single problem with it. The glass isnt broken, and no liquid has ever touched laptop. It jerks around when I touch it, sometimes ignores my touch, sometimes reads 3 or 4 fingers when only one is touching it. The physical click sometimes doesnt work, and I have to use the tap-to-click. I am in Portugal, so my machine has a 2 year warranty by law. Is this a problem Apple will fix? Or can I do a quick at home repair?
