Under more info in the power section, it says to "check battery". I have noticed that my battery barely lasts as long as it used to. CoconutBattery also states that my battery capacity is nearly halved. And what is up with the Age of my mac! 24458 months old! My MBP is a mid '07 model so it concerns me that I would have to replace my battery so soon. Is this the tell tale signs of battery death? Also I forgot to add that I followed procedure to re-calibrate the battery last night. Seems to have done nothing as I can tell.
