Thanks for reaching out to us on HP Support Forums. 🙂 I came across your post and would like to help.
I understand that you have an HP ENVY Notebook - 15-q218tx laptop. I read that the touchscreen stopped working after upgrading to Win10.
I recommend you to perform the following steps to isolate the issue and arrive at a fix:
- Power off the laptop.
- Remove the battery out.
- Disconnected AC adapter from the laptop.
- Press and hold the power button for 15 seconds.
- Reconnect the battery and plug the AC adapter.
- Power ON the laptop.
If the touchscreen still does not work then I suggest you to perform the steps as mentioned under "Screen does not respond to touch, or responds intermittently" from this link.
I sincerely hope this fixes the issue. Let me know the outcome. Cheers! 🙂
