Lenovo Flex 4-1470 Auto touch/Ghost touches issue

Hello,

 

I have had my Lenovo Flex 4-1470 laptop for about half a year now, have always taken careful precaution when carrying it, etc. Recently, Upon touching the touchscreen on the right side and bottom of the screen, I am experiencing these "ghost" or "phantom" touches where I touch that part of the screen and it presses on a random part of the screen. The middle and left sides of the screen do not seem to be affected, however, the top of the screen seems to refuse to calibrate to my finger correctly despite calibrating the screen many times.

 

I have updated the touchscreen driver to find that I already have the best and newest version so that cannot be my issue.

 

I have seen that this was a common issue on the Yoga 3-14, and that there was a firmware fix to this...

 

So far the only "fix" I have seen to this issue is disabling the touchscreen altogether, but I bought this laptop specifically for the touchscreen capabilities.

 

I have not physically damaged the laptop, so I am curious on why this is happening. 

 

Is there a firmware fix or something to that extent or will I have to send the laptop to Lenovo and get it repaired?

 

Any Help would be appreciated

Re: Lenovo Flex 4-1470 Auto touch/Ghost touches issue

Hi there, Kaitlyn         -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

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).

 

Can you try the following? 

 

  1. Under theDevice ManagerHuman Interface Devices, can you do a right click and disable on anything that says HID-compliant device (this is the driver that controls the touchscreen). 

 

  1. When finished, reboot the system and observe if you still get the same issue.

 

Update us how it goes.

Hello,

 

As stated previously, I had already tried disabling the HID-Compliant touch screen.

 

I had tried what you said anyway I had disabled all the HID-Compliant drivers, restarted my device, enabled the drivers again and the problem still persists.

Why not try a System Restore back to when it was working?

Also, update Video drivers
