I have an HP ENVY TouchSmart, Windows 8.1 and 64-bit operating system and yesterday my touch screen was working fine, and today I turn on my laptop and it doesn't work at all. Keyboard works fine, mouse works fine. everything but the touchscreen. I thought it could be complications from a very recent update but It was updated on the 17th. Under my system information it says, "Pen and Touch: No Pen or Touch Input is available for this display". I don't know if that's unusual. I've restarted it, and tried steps to fix the problem like "calibrate my screen" but i can't seem to find the settings to it. In my Device Manager settings, I can't seem to find anything relating to touchscreen software, if there is any? I take good care of my laptop but I don't know the first thing about it. There is no damage to it.
When troubleshooting Hardware and Devices, "The driver for eGalaxTouch EXC7910-1037-11.01.01 is not installed."...
Problems found: eGalaxTouch EXC7910-1037-11.01.01 doesn't have a driver-Not fixed.
Hardware changes might not have been detected-Detected.
I've checked if anything neds to be updated. I dont know what to do from here. Is there anything that I need to install?
