I've been using my MacBook 2.0 GHz Core Duo since I bought it around July and just noticed that the battery meter that is on the battery on the bottom part of the MacBook flashes while it is being charged. Is this normal behavior? I only saw it because I turned the lights off and saw the reflection on my desk. If I unplug the power, it stops flashing after about 10 seconds and starts again as soon as I plug it back in. I'm not talking about the small LED on the MagSafe for those who have trouble reading.
