My CD MacBook trackpad button is starting to feel a little weird in the middle, sometimes not even accepting a click. My battery was bulging and I replaced it (paid for it, didn't think to try my luck at getting a free one). I recently had my top case replaced, back in early April. Do you think this is covered under warranty of that or is there something I can do myself to repair it? If I take the battery out, I can see a button thing and may be able to adjust it, but not sure what is needed. Any suggestions on what I should do?
