    I have a unibody macbook pro 15 inch, 2.8 Ghz, 4gb ram, 500Gb HDD.

    There are various display settings like 1440x900, 1344x840, 1280x800, 1024x768 and so on till 640x480 (descending order).

    Will the battery consumption vary at different display settings?

    If so, how much of a difference will it make?

    Thanks in Advance.

    It'll probably save you a few minutes of battery power, but it won't be worth the pain of working at 640x480 on a 15.4" panel. Cutting the brightness of your display will do better things for your battery life than changing the res.

    Thanks a lot for the response. What kinda of difference will

    Adobe RGB (1998) vs Generic RGB Profile vs sRGB IEC61966-2.1 vs Color LCD have on battery consumption?

    Thanks again

    none. I seriously doubt you could reliably measure the difference in power consumption from running at a lower resolution either.

    you shouldn't be using AdobeRGB, Generic RGB, or sRGB as the color profile anyways. Only use profiles created for the monitor, for example Color LCD, or a profile you create yourself via the monitor calibrator.
