    portable computer (lenovo): the cooling fan start to work every 30 seconds many times. what to do?

    i've lenovo 3000 n100 0768 flg.

    when i'm out of windows xp it seems to be fine. for example. when im in the bios settings the fan seems to work fine.

    on windows xp the fan working many times for about 30 seconds and then about 30 seconds rest.

    i've tried reinstalling windows xp but it wasnt helped.

    as i remember the problem starts since buying the computer.

    suggestions?

    thanks,

    Blow the dust out of the heatsink.

    You can probably change fan settings in the power manager.

    The regularity with which the fan is cycling on and off suggests either a failure in the temperature sensor, or a heatsink that isn't doing its job and allowing the near-idle CPU to overheat. The cycling wouldn't manifest itself in the BIOS screen because the BIOS doesn't have half a million background tasks like Windows does, so the CPU usage is lower.

    so what do you suggest to do?

    i haven't saw fan settings in windows xp.

    there is no dust i guess. it's pretty new computer.
    to take it to lenovo lab?

    its summer... hotter ambient temps will cause the system fan to run more often and faster, anyway.
