So as the title says my battery has become worse and worse over the last few months. I bought the macbook in August of '06. My battery seems to not last as long and also when it gets down to about 20% or 25% it just shuts off. no warning or anything. I have attempted to recalibrate my battery numerous times but it doesnt seem to help. I am attaching my coconut results. Take a look. What would you guys do in my situation?
