Can anybody offer me any advice on this touchscreen for my cousins laptop? It's an HP Envy x360, model: 15m-cn0011dx. I followed HPs You Tube troubleshooting video on it - tried literally everything, and the touchscreen still does not respond. This even includes when I just boot to the BIOS and run diagnostics. I also re-flashed the BIOS, it still does not work. The laptop is only about three years old. I don’t know if it would be the graphics card, or replacing the entire display or if you can just replace the touchscreen? My instinct is to just leave it the way it is that it’s going to be too expensive and too much aggravation to fix, but does anyone know anything about this? I don't want to throw parts at it not knowing what the issue is, and my cousin does not know when the last time was that it worked. He gave it to me to fix that the keyboard and touchpad would not work - that was just a software conflict with a small Intel program. So that issue is fixed.
