odd, macbook battery thing.

I have thought my battery in my macbook pro has been dead like a gone to the fishes, needs to be recycled thing since Feb. Since I've plugged my computer into the power source at my house, the battery is charging. Um, I have no explanation for this. MD power gives better charging does not seem like a rational explanation. Anyway, I still need a new battery, but I could possibly go without a cord for an hour now. Weird.
