Windows 10. I replaced the LCD screen/bezel assembly and the touch screen functionality isn't working. The screen works fine otherwise. I checked all of the cable connections and made sure they are seated firm and secure. I confirmed that the driver for the touch screen sensor is the most current one. I tried it with tablet mode enabled and disabled. Any help is greatly appreciated! THANKS!
Using the touchpad, right click the taskbar. Click "Show touch keyboard button". If you do not see it listed there, then the operating system has not installed the necessary component driver for the touch screen. Or, you installed the non-Touch LCD panel (part 4NDDJ) instead of the touch LCD panel (part Y97G7 or 6Y0KK).
I believe you're right on the wrong LCD panel. I am working with my supplier right now to resolve. Once I know for sure I will come back and mark this as the ANSWER. Thanks!
