I have a Surface Book with Performance Base, i7, 1TB. When I open the lid of my Surface Book, there is a loud clicking sound, immediately when the lid comes to a rest position. The sound appears to be coming from the hinge mechanism, inside the clipboard. I don't think the sound is that of the screen/clipboard settling on the keyboard base. There is no sound when closing the lid, only when opening it. I have uploaded a video to YouTube, showing the clicking sound when I open the lid of my Surface Book: Is a clicking sound upon opening the lid normal? Could anyone with a Surface Book Performance base: -open the lid, and let it come to a rest position, is there a clicking sound? Thanks!
