    Sudden Motion Sensor not working
    My sudden motion sensor has stopped working. It is turned on, I checked with

    sudo pmset -g
    and it says it is turned in I even tried turning it off with

    sudo pmset -a sms 0
    and back on with the "1" version of the command.

    It displays that it is on, but in the system profiler is says it is disabled, and it is definitely not working.

    I am running 10.5.2 and have all the latest updates. I called Apple Care and they could not figure out a way to fix it so they set up a return for me. I have to send it in and have it repaired but I would much rather try to fix it on my own. I don't want to be without my laptop. So if anyone has any suggestions it would be greatly appreciated.

    Same Problem
    Hi, I am experiencing the same problem here. Terminal gives me a "1" if it is turned on, and a "0", when I turn it off via terminal.

    In my system profiler however, the status stays "deactivated" and stays that way. What to do?

    As the OP did: Give Apple a call or take it in to your local Apple store and have them look at it. I don't think it's something you can repair yourself since it's probably built into ROM.

    To the OP: As above, it's not something that can be repaired by the user.
