    I bought a new imac on 13th June.
    No problems till now. Al good.

    Today morning, when i switched it on, I saw that the back fan is moving with more speed and sound .
    Earlier, I never heard the fan sound.

    Also, on startup the brightness is set to max , while my settings was very low brightness..

    Howcome, its starting with max brightness now, when I dont have changed anything ?

    And what about the fan sound and speed ?

    And yes, does the iMac has a battery also ?
    For what ?

    Its always plugged to AC current, then what is the battery doing ?

    I never knew that.
    Just downloaded istat pro and it shows HD 35 degree and Battery 55%.

    Wht is it ?

    Are you sure by battery it means the bluetooth keyboard/mouse?

    I mean, all computers have a small, internal battery for keeping time and everything, but it doesn't really depreciate so fast.

    Your problem sounds pram/smc related. Might want to restart them.

    Yes, this sounds like the actual time when you should try resetting the PRAM and SMC.

    PRAM contains boot information and other stuff like screen brightness.
    SMC has settings for fan control and other related things.
