HP ENVY TS 17 Touch Screen malfunction (ghost clicks)

HP Recommended

HP ENVY TS 17 Notebook PC

Product number: E8A11UA#ABA

Windows 8.1 64-bit

Intel(R) HD Graphics 4600

System board: 1965 KBC Version 93.51

System bios: F.56

 

Good day,

 

  My screen was replaced very soon after purchasing my laptop (dead pixels) and I would like some confirmation that the problem I am now experiencing is related to the hardware reinstallation before taking it back to the service center.  I did not experience this issue prior to the replacement.

 

During the boot into Windows, or some times after a day of use, the screen malfunctions with several visible "ghost touches" on screen (I have the "Show visual feedback when I touch the screen" enabled).  The touch functionality is then disabled, with the Windows Event Viewer System warning:

A multi-touch device reported inconsistent contact information.

 

 

Some times it is possible to reactivate the touch screen functionality by uninstalling the "HID-compliant Touch Screen" device driver and then scanning for new hardware.  

Restarting usually resolves the issue, but occasionally the system does not recognise the above driver and lists it as an unrecognised device in the USB controllers section of the Device Manager. 

I ran the UEFI touch screen test a few times - it usually passes, but there was one time when the touch screen was disabled and you couldn't run the test.

 

I have refreshed my PC, but this did not help. 

 

Any feedback would be appreciated.

 

Thanks

I understand that after replacing the Touchsmart screen, you are getting ghost touches.  You did a refresh on your notebook, but it did not help.

The "Troubleshooting Windows 8 Touchscreen Issues" article does not discuss ghost clicks and is no help. I have the same issue, and it seems to appear after the lid is closed and the laptop goes to sleep. Rebooting fixes the issue. I saw one forum post that had a link to an updated touch screen BIOS, but that link was dead, and I can't find that post anymore.

 

Researching the forums has turned up no actual solutions, only frustrated users. Any suggestions for a real fix?

Good day,

 

  My suspicion is that the issue is being caused by static build up on the touch screen that then registers the false clicks.

 

I was requested to take it back to the Service Centre, but haven't had a chance yet - will give you some feedback after they have had a look.

I have had the same issue.  I finally just posted something about it.  I didn't refer to it as ghost clicks.. which makes sense.  I find if I turn the power button off and then back on.  It stops for a time and will start doing it again.  It sometimes does it to where I'm several web pages away depending on where it clicks itself.  It was sent back for a warrant issue and I asked it be looked at, it was returned with no change.  I understand your frustration.  I just joined the forum and I hope I can mark your report to check back and see if you receive a "fix".  We're not the only ones out there, I just found several including yours.  Again, it caught my eye because of your description of it invoking itself.

I'm almost certain this only occurs only after the computer sleeps.  I'm trying to disable all sleep options and change power button and lid close actions to hibernate only.
