Hey guys, I've owned my 15 inch Macbook Pro for a little over a month now, and I've noticed that generally the keyboard requires a bit more of a tactile pres than others that I've used, but my S key is especially annoying. I can depres it all the way lightly (<-- notice the lack of second s in depress) and have it not register. I have to press a fair bit harder. I'm sure I'm not the only one here who's had problems with the keyboard. I'm just wondering if there are any obvious fixes before I end up taking it in to a store. I've tried pressing down really hard and moving the key around a bit and canned air, but I don't think anything's under the key, it seems like just a mechanical issue. Is there a way to fix this? Thanks in advance for any advice.
