In fact, when I went back to really listen hard to my SP1, I could just about hear it there too (although to be honest, it was overpowered by the fans)
I hope it's not really, because I'd love to think that Microsoft had finally fixed these issues!
You scared me OP before I put SP6 order. I found my SP6 is vet quiet . But I found the battery drains so fast, maybe it’s new, I open many apps in the background.
