I've noticed an interesting behavior with the charge port LED on my MS. When I plug the car in, it turns blue and eventually turns off when the car locks. I've noticed that sometimes when I go into the garage, no keyfob in range, the blue light will be on. I go back a while later and it's off again. Does this have something to do with the car "waking up" a little to perform battery maintenance functions? Or to surf the internet a little to relieve the boredom? Or preparing to go out for a snack?
