    So I just played about a 35min game of SC2 in windows 7.

    My battery was plugged in and fully charged to 100%. After the game was over, its at 60%?!?!?! How could that happen plugged in, with the charge light green the entire time....???

    The power adapter itself is not enough to power the computer when running at very heavy loads. The battery kicks in to give it a nudge. It's perfectly normal.

    Nah, thats not true. There is no load high enough on the MBP to exceed the 85W power adapter. His MBP should have stayed at 100%.

    theres gotta be something wrong with that. that means at that pace, your battery wouldve actually died while plugged in.

    :confused::confused::confused:

    My battery remains at 100% if I play games like SC2? I never needed to recharge it.

    Could you for some reason have used a MacBook or MacBook Air adapter?
    The MacBookPro uses a 85W adapter, the MacBook (and 13 inch MBP) uses a 60w and the MBA uses a 45W adapter, they all look the same.

    My i5 does not loose any battery from playing SC2.

    40% loss in 35 mins is like playing unplugged..

    Just played some NFS World in Windows 7. Battery stayed at 100%. Your MBP must have never been charging. The MBP might have been reporting to the charger that it was at 100%.

    The only thing I have thought of is I wasnt using the extension 3-prong.

    The light was green the entire time, so I assume the connection was 100% up.

    I have a normal 85w adapter that came with the MBP. I cant explain this issue. Im going to test it tonight with the three-prong.

    Ill report back.

    It seems as though the power adapter was NOT plugged in from how the laptop was dying. An hour of SC2 with 330m seems like it would take about 40% of the battery. But again, the green light was oN the entire time. I did NOT feel the power brick, I should have.

    WIll report more back tonight, thanks guys.
