I haven't seen anyone here mention this but I currently have two SP4s where the Touchscreen stops responding and also the Pen stops working until you reboot. However I am not the only one Surface Pro 4 touchscreen not responding? • /r/Surface You can attach the keyboard and continue working with keyboard and trackpad although once the trackpad stopped also leaving me to reboot via keyboard only. Anyone else getting this problem. It's actually worse than the Display driver crash issue although it starts the same with no response except you never get response back until you reboot. This would be a disaster in a note taking scenario, by the time you recovered you would miss volumes.
