Try the below links (in an orderly fashion)
if the touchscreen doesn't work on BIOS (access by restarting & tapping on F10) : contact HP for an LCD replacement via 1800-474-6836.

I have also done the firmware updrage, and the touch screen does not work anymore.
I did whatever is said here, and a full factory re install, and the screen does not work.
I've sent a essage to HP support, I hope they will answer. How to go back to factory firmware and make the touch screen work again.

Upgrade BIOS, drivers, reset system etc. doesn't help in my case.
I think touchscreen is good, but I put incorrect firmware into controller.
So system does not see touchscreen (on hardware level) because controller does not work.
I hope what HP make upgrade for touchscreen controller firmware for my laptop and then everything will work.

Thank you very much for ypur comment.
Yes, you are right, I did all that and it didn'twork.
I hope HP will upgrade or publish a touscreen controller firmware. I still have no reaction or answer from them
Let's see this week. I am frustated with this issue, sincerely except this, I like a lot the spectre, it's really light and powerfull. I have the x360 g2 with the i7 6600, 500 gb of hd and 8 gb if ram. It's really a nice piece of art in such a light and thin envelop.
I was trying simply to use a stylus pen with it.

I wonder why HP is reluctant to release a touch screen driver on HP Support. I don't believe the touch screen issue due to a missing driver or hardware detection failure can only be resolved by screen replacement which is a much more expensive solution. What a loss for HP.

Well, after contacting HP CUstomer Services, they first try to solve the problem on-line, but it didn't worked out. And, finally, they've changed the PC. Now, all it's working OK. So, apparently it was a hardware problem.
Customer Services was good, I cannot complaint, I rather congratulate HP services. A good Customer Service is becoming rare these days, that's a good value. Thanks HP.
