yes, the battery has been calibrated... it did reach 100% before, but now is stuck at 99% and isn't charging to full. The LED ring on the adapter is green (i.e. fully charged). It's not really a big deal to lose 1% but I don't want the problem to get worse. Plus the PB is brand new. Which is more likely: that the indicator is just reading wrong, or that the battery is not fully charging? anyone experienced this? thanks.
