I recently purchased a new Dell U2713HM from shop justcomp (just.ru ), computer shop in Moscow. I out of interest checked the tag on the back of the monitor (center bottom on back) and to my surprise the serial number is different from ones listed on the box shipped and the calibration report.
Oddly enough it seems that the track pad/mouse pointer stops working when the screen is black. e.g. during the time the screen is black the pointer on the screen doesn't move. I thought it might be related to the back light on the keyboard or the touch buttons.
