My Mid-2009 Aluminum Unibody is a great little notebook, especially with the Hybrid drive I recently installed. However, I have a small problem with the headphone jack. I have a Bose Noise Cancelling headset but I loose connection all the time unless the jack is pushed absolutely all teh way in. The slightest bump and the jack will back out ever so slightly, but enough to loose connection. I am constantly having to push the jack in. It the headphone input on my Macbook something that I can replce myself?
