    Hello all, im new to the forums, i searched around a bit but havnt really found anything to answer my question

    I have a early '11 15" mbp (2.2,6750m) running windows 7 ultimate via bootcamp

    i just got battlefield 3 on Wednesday and proceeded to overclock my fx card as described in the tutorial on the forum. (which makes the game run awesome! btw)

    I just noticed something, however, after about 2 hours of playing my battery is at 89%. It has been plugged into power the entire time and was fully charged when i turned the computer on. (i am 100% sure about this)

    the card is set to .990 V as opposed to 1.0 V when overclocking

    I havnt tested this with the fx card not overclocked but i can say for sure the only time this has happened is when playing battlefied 3

    is this something i should be worried about?
    my mac does not get any warmer than watching flash video, and i have it raised for proper ventilation.

    in fact, it probably gets warmer watching 720p flash video

    thanks for any help, seems to be a bit of a strange issue and this is one of my early ventures into overclocking

    This is not something you should be worried about. If the computer requires more power then what the MagSafe can provide, it will draw it from the battery.

    Yep 100% normal!

    It's normal during peak demands, as Intell said. This should answer most, if not all, of your battery questions:

    -%11 isn't that bad every 2 hours. As long as you have the MagSafe plugged in then you will be just fine. Anyway, it's not like anyone would play BF3 straight for any more than 3 hours. Unless you are a uber BF fan!

    fully charge your MBP, then play BF3 for the same 2 hours exept without the MagSafe charger any of that time unless the battery get real low. Then post your results here.

    i imagine the battery would last about an hour without it plugged in, but i can give it a go

    what worried me was that ive never had that happen before on a laptop (i had a high end asus before)

    it makes perfect sense, just making sure it was normal and i wasn't about to ruin anything
