I seem to be having an issue of the computer misreading the battery or something. I'll be using the computer and the battery indicator will state that I have maybe 45 minutes left (maybe 30%) and then the laptop will go into sleep mode all by itself. It won't come out of sleep until I plug the adapter in. After plugging the adapter in, the battery icon reads 0%.

What's the deal?

This seems to be a simple calibration thing, but I'm basically doing the calibration albeit accidently (charge full, run it down until it falls asleep, charge back up).

As a side ntoe, strangely enough, with coconut, the battery reads as 99% (4159/4200) at full charge. So I don't think it's a problem with the battery.
