Answer to: How to reinstall touch screen driver? My touch screen stopped working.Hi - I had the same issue re device code 45 on a Toshiba laptop, two years old. The problem turned out to be the hinge through which the cables ran for powering the screen. Moving the screen very carefully to nearly upright it was possible to run the touch screen but it was not very easy to see it. Poor design meant the hinges were quite weak and must have pulled against the cables.
