Two days ago my touchscreen worked fine and then all of a sudden it stopped responding. A box keeps popping up saying usb device not responding and I am assuming it's the touch screen. In the device manager it says that it's an unknown device, so I guess that the touchscreen driver was deleted somehow or something. Any suggestions on how to fix this?

Welcome in lenovo forums
there is no driver for the touch screen .. all what you can do from now is to restore the machine to the factory setting
Please let me know
