    Assuming the 10.2W power draw reported by Kevin

    4 cell battery = 14.4V * 2.6 Ah = 37.44 Wh

    t = 37.44 Wh/10.2W = 3.67 hr (at most)

    My last experience with the last set of chips, it has been about 2 hours at best. I'd expect about 2:20 with the latest power-conserving chips. This is with brightness at 75%, which I deem to be an acceptable brightness.

    Yes but with and LED screen and even lower brightness, you can do better.
