HP ENVY m6-n012dx Notebook PC
My touch screen has worked for 3 years now. I have updated from Windows 7 to 8 to 10. Through all the updates, I have had no issues with the touch screen. Now, all of a sudden with no warning signs, the touch screen is GONE! The notebook appears to not be a touch screen when I know it is. I have looked for the driver, and there is nothing there. I am not having any other problems (i.e. touch pad is fine). HELP! I need the touch screen back!
