I just received my new x17 R2 two days ago. These two issues come with unboxing. First, it can not go to sleep by closing the lid. I asked Dell support and I tried all methods that they gave me, and all software is the latest version, but it still does work. Then I figure out this is not an x17 R2, software, or setting issue. The laptop successfully sleeps when I put the iPad's magic keyboard close to the x17 R2 because the iPad's keyboard has magnets that can be recognized by x17 R2. My laptop cannot recognize its lid by closing. Second, the left side speaker plays horrible distortion while the volume is higher than 50%, and I have heard many people have the same issue. This is a device of almost $4000. I can't accept it has this kind of ridiculous issue. I am tired of Dell support sending me the video, again and again, this is 100% hardware issue that comes with the unboxing.
