    Hi. Seems we have a small problem with our touchscreen.
    The laptop was dropped at one point, the frame and cover were damaged but the touchscreen itself was not hurt. We replaced the damaged parts, but now the 'touch' part is not responsive. In device manager it is listed as "LCD 1440x900", and when we click on the "N-trig DuoSense Digitizer" it comes back as "no devices found". The frame and front screen cover were all we changed, everything else remains original.
    For a couple weeks, while we were waiting for the parts to come in the mail, we used the computer with the screen propped up inside the old cover, (stupid, yes, but it's our only computer). During this time "N-trig" came on a lot, because the mouse would move erratically by itself.
    We can't seem to locate the device or drivers. Any help you can give us will be much appreciated.

    The cable for the touchscreen digitizer may have come loose during the LCD replacement.
