    I noticed some kind of hissing noise from my XPS M1530. Firstly, I thought it was coming from my Hard Drive but it seems it's my processor that produces that noise.

    What's wrong ? Did this ever happen to any of you ?

    Thanks in advance

    It is a known issue with Core Duo / Core 2 Duo processors unfortunately.

    Yes, indeed I've read some things about it on the Internet.
    Should I be worried and ask for a replacement ?

    hissing noise eh? are you referring to some type of crackling/loading/type thingy lol coming from the upper left corner of your keyboard area?

    cause' I have that too, but it's really only noticeable when it's really quiet and i'm loading a bunch of stuff

    It's the processor entering different state that's causing the noise.

    I've read it somewhere that you can turn off a couple CPU state through RMClock to make it go away. Unfortunately the details has slipped through my head.

    Also, this seems to be a problem for pre-Penryn chips. I haven't heard anything like this for those 45nm monsters - Well, except you, that is. :)

    I noticed this too. It's that crackling noise that you hear constantly near the "XPS | M1530" sign (upper left side of the keyboard). What the hecK right?

    It's a high-pitched squealing noise apparently coming from the upper right side of my computer, not the left one.

    EDIT : In fact, it seems I can hear that noise from the left side as well as I can hear it from the right one.

    My XPS makes a random squealing noise, it's not constant just random
