Hi all, I have had a MacBook Pro, 10.5.8, for almost two years now. My battery started going crazy two days ago. It would be fully charged, and within 10-15 minutes, it would drop to 50-something. According to CoconutBattery, my current capacty is 800mAh, comapred to the poriginal 5500 mAh!!! What is going on? Is there any way to fix this?
