I left my new i7 MBP on the charger last night. I have not unplugged it. I am now doing some intensive video processing, and the battery is at 74%, and it has not started to charge off the plugged in charger yet. There are no indicator lights lit on the magsafe, neither orange or green. At what point will it start charging the battery again? Is this normal? I am sure that if I unplug it and then plug it back in, it will start charging, but I don't feel I should have to do that..... **Edit** I unplugged it and plugged it back in at the magsafe tip and it still wouldn't charge. I had to actually unplug it from the wall, and then plug it back in to get it to charge. Have any of you seen this behavior before?
