    What are you doing w. the computer? It should easily last 4 hours as long as you're not playing games or watching a lot of flash vid's.

    I would run the battery all the way down till it goes to sleep on you then turn it off let it charge all the way back up and see how it goes.

    And turn the brightness down to 50%, bluetooth off, and wifi off if you don't need it.

    Powerpoint & Word won't kill it unless one of them starts running away. Watch your proc. usage with either Activity Monitor or iStat. Should rarely go over 50% in normal use.

    Web surfing as in what sites? I can go to YouTube and kill my battery in 1 1/2 hours if I try.

    Open Activity Monitor

    Show "All Processes"

    Sort by CPU usage with highest on top, take screen shot.

    Is this your first mac? By any chance are you new to OSX and aren't closing your programs properly?

    Maybe this is a sign that you should pay attention in class...

    It's probably Powerpoint, especially if there are transition effects in the presentation.

    You should try calibrating your battery to see if that helps. Also read this article from Apple to get other general tips on prolonging your battery.

    Calibrating a battery on a new machine won't buy you 2-3 hours of usage.

    I'd like to see how you're running it to get that poor of battery life. I suggest you download iStat Menus and set it up to monitor your processors to see what's eating up battery.

    I know that if I don't keep an eye on where I surf to & MS Office, I can have runaway processes that will kill my battery much faster than casual use. Flash sites are killers and they can have animations in windows you don't even see. Not just porno sites either. USA Today has gotten me a few times.

    Not much to add other than that the 7 hour promise isn't a marketing lie. It really runs that long, especially for the kind of "surfing & word during classes" use you described. Even mid-to-heavy use (videos, flash, downloading, etc.) should give you 4-5 hours.

    Could be a set of unfortunate coincidences (some program getting caught in an unusual power-consuming loop, maybe starting at 89% instead of 100% without noticing... etc. etc.).

    Try it again under more controlled circumstances... if you haven't already. If it lasts, return it.
