Okay, so I've had my Macbook for 2.5 years now and it is the 2008 White Model. For the past few months now, I've noticed that my track pad button (this isn't the unibody track pad) has sunk in. Like it literally doesn't even push in. I checked online and read various methods to see how to fix, such as trying to remove dust/lint possibly stuck under, but that is not the problem. You see, when I remove my macbook's battery, but trackpad button works just fine. I'm able to click on it perfectly and I can feel the button clicking. When I put my battery back in, it feels like the battery is pushing against my trackpad and I'm not allowed to click on it. It just becomes flat or "stuck." At one point, I was able to click on things on my computer simply by tapping the right side of my arm rest. Yes! The arm rest! What is going on here? This is so frustrating because even the slightest touch to the trackpad will cause me to double click. When I type, this results in highlighting the entire paragraph and deleting everything. What is going on?
