I have an Envy 23 that was touch/pen capable until only a few days ago. It now shows "no pen or touch available for this display." The HID compliant for touchscreen is hidden and cannot install, update, or rollback driver because the hardware is not connected. I have attempted to rollback Window updates, install Window updates (all), restore to an earlier time when the PC was working with touchscreen, update and rollback drivers, reboot to the manufacturer set up, etc. I would attempt to calibrate except there is no option for that. Many of the suggestions require steps that are no longer found on the PC.
The onscreen keyboard has even disappeared.
The only suggestions I can find from forums, web searches, and the customer care number is to winkey + X and update the driver in the HID --- No possible since it cannot find the hardware or hardware is not connected. What hardware? It is not in the hardware recovery, reboot, search of PC, and I did not buy this separate. I have looked for calibration options but they do not exist on the PC as far as I can find. I have looked on HP's site for the driver(s) or other options and nothing.
Is there a way to get the touchscreen driver, hardware, or whatever is needed fixed? I purchased this specific for the touchscreen and to lose it kind of defeats the purpose of having it.
