My MBP Core Duo is about 8 months old now, and the battery has been getting noisier every day. When I disconnect the power, the noise ceases (and all is right in the world), but when connected, there's a high pitched squeal/squeak that is driving me crazy. What to do!? Has this happened to anyone before? I tried searching this topic in the forums and on google, but all I could come up with was MBP fan squeaks, etc. And this is not related. Please help!
