A good question. My hunch is that it will. I believe there is a grounding issue allowing computer noise to bleed into the audio circuit, and that if that is fixed the problem should be solved with the internal speaker as well as with external speakers. UPman?I want to know if this is going to fix the external speaker issue?
Still, I would also feel pretty nervous with my return period running out. I am struck by the fact that some units display no noise, while some have "some" noise (like mine), and that some others have an unacceptable amount of noise. Based on what m42duster is saying, I would be wondering if my "unacceptable noise" unit will be acceptable after the mod....tough decision to make there.
