I'm rather shocked and somewhat disappointed to see the battery in my MacBook failing completely! Again. This is only the second time it's done this in a period of three months, I'm beginning to wonder is the charge circuit within the machine faulty or Apple replacement was just a dudd? What are the chances??? Upon bootup, I fire up System Profiler and it tells me the battery is installed but has 0% charge, yet it refused to charge it. Has this happened to anyone else who owns the last revision of the MacBook White 2.1Ghz?
