VaioCEB321

Hi, I purchased a Sony Vaio laptop VPCEB4E4E a few weeks ago. It is emitting a very high pitched sound, which is causing me a headache. NOTE: I'm not referring to the annoying high pitched sound which comes out of the left side of the keyboard, I also get that sound but is not as big as problem as the other higher pitched sound. The frequency is so high that I am unable to pinpoint exactly which part of the laptop that sound is coming from. Im not sure if others can hear it, It is emitted contunuously, whether the power lead is plugged in or not. It is heard even when standing a couple of meters away from the laptop. It is continuously in the ears causing me a headache. Only by switching the laptop off the noise will go. I have read the following, which has not helped: http://www.sonyinsider.com/2010/01/21/new-sony-vaio-f-series-encountering-buzzing-or-high-pitched-whine-issue/ My issue is whether I will be able to get a replacement or fix, as not many people may be able to hear the sound, and the people at PCWorld only do something if they can physically see/hear the problem. Any help would be appreciated
