my VGN-N31ZR/W sounds like mosquito

I bought notebook yesterday, and after few hours of work i start to hear high frequency sound. Probably it is a hard drive. It's quite irritating. Is it a malfunction? Anybody faced this problem?

Hi Alexagen,

A high frequency sound is not normal for a Vaio. Take it back and demand a replacement or a refund.
