Re: S400 Touch - Touch Screen stops working

I have a Lenovo s400 and the Touch screen is not functioning.  The details highlighted in the blog also describe exactly what happened to my computer - I updated to Windows 8.1, it worked intermittantly for a week and would cease to work after the computer slept for a brief time, then there were ghost taps in the top corners that were inceasant, then it no longer functioned at all.  The online support staff attempted all of the software updates to no avail.  I am looking for any type of help to resolve this problem.

S400 Touch - Touch Screen stops working

Hello, I decided to post it as I cannot find a solution been trying to find a solution for 3days, but to no avail..

 

My laptop's touch screen function stopped working last saturday, i don't really know what the problem is,

Here's what I tried to check/do based on the touch screen problems here in the forums

 

  • HID Touch Screen -> Installed properly
  • HID Service -> Set to automatically start-up
  • Physically - Perfectly taken care of, no drops since bought.
  • Tried to revert back to windows 8 -> did no good
  • Upgraded back to window 8.1 -> did no better
  • There is no wacom touch gesture(w510 solution) to uninstall
  • Hardware problem? -> no idea. hopefully not the cause.
  • Windows 8.1 issue? -> not sure but i have been able to use touch gestures for windows 8.1 since it was released until last saturday

Re: S400 Touch - Touch Screen stops working

hi paul_peria,

 

Welcome to Lenovo Community Forums!

 

Can you try Opening Device Manager and open Human interface Devices

 

Uninstall everything that starts under with "HID-"

If your are not done uninstalling all and it asked for a restart choose restart later then continue uninstalling the one's that starts with HID-

 

Then Restart your system, check if the touch functionality works.

 

Can you also check under System Properties windows if it shows touch input detected

I did what you said, but again.. no sign of improvement..

and also the 10-point multi-touch is detected even before removing the HID-s but it doesn't detect touch input

Re: S400 Touch - Touch Screen stops working

I'm bumping this thread because I'm having the exact same problem.  My touchscreen on my s400 Touch stopped working a few days ago.  I upgraded to windows 8.1 a couple weeks ago.  I too was able to use the touchscreen since the upgrade, then it stopped working a couple days ago.  If I'm remembering correctly it did work for a short time since it stopped working, yesterday I believe.  This has me worried as well that it might be a hardware issue.  I really hope not.

 

Anyway, can anyone recommend to me which solutions to try first?  Is the list the OP posted a good order to try before trying the steps recommended by others? The only fix I've tried so far is installing new windows 8.1 drivers.  I did this today.  This did not work.  I did not, however, remove any other drivers or other software before installing the new drivers.  Should I try uninstalling any old drivers first and then reinstalling?  Any help is much appreciated.

Re: S400 Touch - Touch Screen stops working

What I listed before are some solutions from other forums that also had.the same problem on a different device, as an update with my laptop that is currently at a service center, they said that its a hardware problem as they are not able to resolve the issue through software side, try do and reinstall drivers, maybe ot would work for you, but it didn't work for me. If reinstalling the drivers does not solve try to revert to Windows 8.

Thanks, I'm trying those suggestions.  Bad news though.  Good luck with your laptop.

Re: S400 Touch - Touch Screen stops working

Hey there! I just upgraded to 8.1 from 8, and starting having numerous issues...I called Lenovo Tech and they said the S400 is not compatible with 8.1, so I downgraded and everything is working fine except for wifi. Not sure why a brand new laptop is not compatible with Windows 8.1 though??
