Yoga 3 14 Ghost touches on touch screen

Hi everyone,

 

I am experience a lot of problems with the touch screen on my Yoga 3 14. At least once a day I am getting ghost touches, i.e. it starts thinking that the screen is being pressed when it isn't. It closes windows, opens the keyboard and types, etc. I've noticed it mostly in laptop mode, but that may be because that's how I use it most of the time.

 

For now I resort to putting it into hibernation or having to do a full reboot, and it fixes it for a while but always starts up again. It happens in different places on the screen, usually just one at a time but occasionally multiple touches.

 

I've had the laptop for 2 months and have had the problem since week 1 or 2. 

 

Is there any solution to this besides calling support and having them replace the screen/other parts?

Re: Yoga 3 14 Ghost touches on touch screen

hi hucktopia,

 

Welcome to the Forums.

 

Your problem might be similar to this thread.

 

If you barely use the Touchscreen to navigate around, can you try these steps to disable the feature:

1. Press the Windows key‌ Windows logo key+R, type devmgmt.msc and press Enter (this should open the Device Manager).

2. On the Device Manager, click View > Show Hidden Devices and under Human Interface Devices section, uninstall the HID-compliant device touch screen (this is the driver that controls the touchscreen). 

    - Sample image

 

3. When finished, reboot the system and observe.

 

If the above procedure works, you should be able to use the system normally but I recommend that you report the issue by contacting lenovo support.

Re: Yoga 3 14 Ghost touches on touch screen

Neokenchi - am I understanding correctly that it would disable the touchscreen completely? Because the touchscreen is one of the reasons I paid more for a Yoga rather than buying a standard laptop. And would I then have to reinstall to use the stand or tablet mode?

Re: Yoga 3 14 Ghost touches on touch screen

hi there,

 

The above steps will only temporarily disable the Touchscreen functionality (to let you work in laptop mode without the ghost toches). If you switch to Tent or Tablet mode, you will need to reenable the HID compliant device for touchscreen to work..

 

Ghost touches on the screen are most of the time caused by a faulty digitizer (this is the touch screen panel that enables touchscreen functionality) or the Touch panel module (LED panel w/ Touch).

  - Link to picture (page 65-66 of the HMM)

 

Until such time that you contact support for service, I'm afraid this is just a workaround.

 

 

Regards

Re: Yoga 3 14 Ghost touches on touch screen

Hello, I am having the exact same issue described above and this occurs both while docked and undocked. So far only experienced in Desktop mode (probably b/c that's the mode I most often use).

Re: Yoga 3 14 Ghost touches on touch screen

I sat on phone with two different Lenovo Representatives. The 2nd person disabled all applications in my startup directory, as well as, disabled every service that wasn't directly used by the operating system. This fixed the issue. I re-enabled the services that I had to have for work but I left everything else as disabled. An extra benefit is that my Yoga runs even faster at start up. Windows key + x, task manager, then click the start up tab. Disable anything that you don't need at start up. Then windows key + x, run, services, then disable any services that you don't need or make them manual instead of automatic.

Please only do this if you understand the risk. I would feel better if you explain this fix to a Lenovo Rep and let them talk you through this.

 

Regards,

Gary Tipton

Re: Yoga 3 14 Ghost touches on touch screen

Thanks Gary, I've been on the phone with Lenovo service reps several times
over the last week and we performed basic troubleshooting (reboot, remove
peripherals, etc...) as well as more advanced (BIOS setup, disable touch
screen, update graphics drivers) but I'm still experiencing the ghost touch
issue consistently (intermittently). After exhaustive troubleshooting I
have been referred to an issue specialist who has determined the system
likely has defective hardware (they have not specified what hardware but
did indicate an order has been placed for the hw). I'll speak with a
service rep in the next day or two once the hw arrives and will update this
thread.

Re: Yoga 3 14 Ghost touches on touch screen

Well, I spoke too soon. My wife has been on the phone with Lenovo for over an hour. Out of no where it started doing it again. The supervisor she is speaking to now is saying we need to send it back because he believes it is a hardware issue. This really sucks. I use this machine for work and now I'm having to send it back for repair. They refuse to return my money and I'm afraid that the repaired/replacement will develop the same issue. I will keep this thread updated with my results. Once they receive it, they will keep it for approximately 2 weeks so it will be a while. --Gary

Too bad but I suspected you might be back Smiley Sad The only bright spot for me
is I purchased the 1yr in home service so I won't need to send the machine
away.

Re: Yoga 3 14 Ghost touches on touch screen

My 3 14 experienced the phantom touch issue.  At first I thought the touches random, but noticed that they seemed to concentrate in frequently used areas.  It appears to me to be more like a buffer being played back.  With my Yoga, the phantom went away when the digitizer stopped working altogether along with the USB ports and sd card reader.  Anyone experiencing the issue should get in touch with support  Unless you've done some hardware hacking?  You're still under warranty.
