    Unplug your power cable. Look on your keyboard, there should be a symbol for brightness, one for up and down. Adjust it all the way up with the power cable unplugged.

    i don't know if it is possible; it is  a power saving feature
    so if you can disable it, your battery will be low much faster !

    If you are using Vista - Right Click on the Desktop -> Click Screen Saver -> Change Power Settings -> Change Plan Settings -> Change Advanced Power Settings -> Display -> Adaptive Display (Turn Off)
    If you are using XP I do not remember but it should be similar steps.
