My wife's Macbook Air was suffering from the overly sensitive trackpad issue. At first the trick of pressing hard on the diagonally opposing corners fixed the issue but eventually it persisted. I sighted along the base of the computer and didn't notice any bulging but decided to try the battery replacement none the less. So far so good. It's only been a couple of days but the issue had previously been a steady annoyance. Really appreciate this site and its forum!
