MBP Battery Drains When Off

[White Tiger]

Hey folks!

I just got a new 15" Macbook Pro and, while I love it to death, it has one noticeable problem. See, when I plug it in to charge overnight, it'll usually already have a nearly full or fully charged battery already. I know many say you should let it drain once or twice a week, but I charge it otherwise.

Anyways, when I boot it up the next day, it'll have drained to anywhere from 60% to 30% for some strange reason. I checked the system profiler and it tells me that the battery state is normal and that its only gone through two cycles (again, new), yet it'll still drawin when I leave it overnight.

Anyone have an idea what it might be? I mean, I doubt its the battery since (a) I just got it and (b) the profiler tells me its in fine shape.

EDIT: Just to add some details, I'm certain I turn it off before closing the lid and I'm not leaving any peripherals such as my iPhone, iPod, or anything like that plugged in when its turned off. The only thing that I usually have it hooked up to is the charger.

Thank again!
