    Hello,

    I have a 15" Unibody MBP, 2.53GHz, 4GB Ram
    My battery rarely lasts longer than 2 hours.

    When I'm teaching, I am connected to a digital projector, I have the screen brightness at the lowest setting and I am using the integrated 9400 video card. Bluetooth is off and I am connected to the Internet via WiFi.
    My fully charged battery will only give me 2 hours of use in this situation. Does this sound "normal" from your experience?

    Thanks.

    I haven't calibrated for quite some time. I'll give it a try.
