Touchscreen has disappeared from Device Manager

[Sdale83]

I tried it yesterday and did the component test for mouse/touch pad and my mouse didn't work at all.

We have only had this computer for about 2 years.

How long does their warranty go for?

If you have HP Support Assistant, open it, select 'Troubleshooting' for your computer.    There's a ribbon about 1/3 of the way down, near the right side click on 'Warranty and Services'.  Warranty status should be displayed there.

Good luck!

Thank you I checked warranty the other day and it is out.

I need to check if I got Product Care from Harvey Norman.

If I did then it will be under extended warranty with them.

Thanks for all of your help.

I really appreciate it.

Looking  through 'apps and features' I found two EzPen applications; I uninstalled the non-HP one. Touch screen now works.

Apparently (?) EzPen doesn't work on some HP laptops anyway, and installing the second one disables the necessary drivers. In Drivers under 'human interface drivers' I now see all drivers up and running, including the touch screen.

Under 'apps and features' search for 'ez'.  See if you get two EzPen applications.  One is Elan; leave that one and uninstall the other one.  See if that fixes your touch screen.

My laptop doesn't support EzPen anyway; my wife's does.  In any case it's not something either of us use, and I'm guessing you don't either, so uninstalling one or more of the apps shouldn't harm anything.
