    Could this be the frequent distinct "chirp"/"tink" sound I am hearing from the right side of my computer when the hard drive on my 1420 is idle?

    The posters in this forum have said it is just my HDD head re-parking itself, while three separate Dell Chat technicians have repeatedly stated that the noise is not normal, and that the problem could range from a faulty fan to a hard drive that needs to be re-seated. The Dell Chat people said that I should repair or exchange the machine.

    Still trying to decide whether to exchange this computer for another 1420 at the retailer where I bought it... basically whether to roll the dice again and hope I get lucky...

    No - that's HD head parking.

    I think they are talking about the CPU noise in headphones (although they seem to be talking acoustically in the article). I've never heard it really acoustically ie actually hearing it from the processor itself, but I do hear it through headphones and the onboard speakers when the CPU goes into C3.

    It's to do with reference to the so called CPU Whine...

    This white paper was originally intended to be used as Dells escape clause but has since changed to an information piece. It has been revamped several times and pertains to the CPU whine located in the area of the CPU, not from the battery adapter and not with relation to the whine in headphones. Both are separate issues.

    Just found that Dell page:

    Journal ID: 08036SWLDZ
    Article ID: 295216

    So, it works? Where is "the area of the CPU"?

    If this is a by-product of processor efficiency, why don't Dell and its competition bolster the acoustic dampening inside the chassis itself to reduce/cancel the reverberation to our ears?

    Unlike constant fan or disc frequencies deemed acceptable, the CPU whine varies in pitch and therefore cannot be so readily shrugged off as associated 'background noise' since you are rarely able to distance yourself from its presence.

    If this line of thought holds water, then I don't forsee how the influx of Penryn processors will make things any better for end users; its power efficiency is one of its selling points over the Santa Rosa platform, and now we are enlightened to the premise that this very 'feature' is perhaps causing the acoustic aggro with the current generation.

    I don't have any problems with my M1330 despite running bluetooth, wifi all the time. What EMI do you have around your house/office that is interfering?

    Wow. I didn't realise that the noise would disappear when it's plugged into the mains. Damn. When it's plugged in it's perfect. :(
