Touch screen firmware upgrade

Hi,

 

Try the below links (in an orderly fashion)

 

http://support.hp.com/ee-en/document/c02693833

if the above doesn't work: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c02638587

 

Download drivers from : http://support.hp.com/us-en/product/HP-Spectre-x360-Convertible-PC-Series/7527520/model/7791778/driv...

 

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.

On BIOS the touch screen option is not visible. And on windows the options is not available neither.
I think the system does not knows that it has a touch screen but don't know how to put it back to work

Hi, Ernesto

 

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.

Hi ASKlim

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.

Let's see.

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.

Exactly! I'm out of warranty and just because a crappy firmware from their site runined my firmware shouldn't mean I need an LCD replacement. I just need the firmware for the touchscreen! HP please help!

Hello

 

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.
