    OK, I ran calibration procedure for my battery yesterday. Have a fully charged battery did not that if spotlight is on, it changes my estimate remaining time by almost 3 hours, then airport is another 2 hours; leaving me with 31/2 hours......

    What exactly does spotlight do?? Do most people leave this fully on??

    Also, Where can you shutoff keyboard backlight, if you want???

    Spotlight searches the contents of your computer and launches applications. It also indexes (collects data about) any hard drive changes, meaning it activates your hard drive, which consumes energy.

    So, if you're the kind of person that likes to launch applications by searching for them via spotlight, you should leave it on. If this isn't important, and you tend to use the dock or desktop, then you can probably turn it off and enjoy some extra battery time. Or you can turn spotlight off only when you need conserve battery.
