Notebooks & Netbooks

I recently purchased an Acer Aspire R7-572-6423 touchscreen notebook.  It works great for the most part except for the touchscreen seems to glitch out every once in a while.  What happens is out of nowhere the touch screen will start registering a click in the very upper left corner of the screen (as seen by the Windows 8 touch visual feedback) even though I am not touching the screen.  The clicking happens very fast (several times a second) and makes the notebook unusuable.

I can make the clicking stop by touching and holding my finger on the screen near where the clicking is happening.  However, as soon as I lift my finger, the clicking resumes.

To fix the issue, I have to do a touch screen calibration (Windows settings -> Tablet PC Settings -> Calibrate -> Touch input).  However, the calibration appears to be off using this method (I cannot swipe the windows 8 bar to the right) so I then do a calibration reset (Tablet PC Settings -> Reset).  This generally resolves the issue for a while.

I have tried moving the screen into different positions and cleaning the screen but the issue still comes back on occassion.

Any support would be greatly appreciated.

Thanks!

That sounds like there may be a problem with either the touch panel or digitizer on the screen.

My best recommendation would be to contact support in your region for assistance.

I've bought 3 of these for family member. The last one I got had the same issues. I call acer support and they said we'll send you a new one. This is a hardware issues. Don't wate time trying to fix it. The sensor is sending false information to the processor. This system was so bad I couldn't even input anything. I did a factory reset and sent it back as per acer's direction.

All the best.

I have had the same problem - have read through as many fixes as I could find, some worked for a while, touch screen would work for an hour or more then stop, on reboot it might or might not come back.  Totally erradict behavior. Never received any error messages or reports in the event log.  Trouble shooting hardware does not see any problem.

I unchecked the box in all USB device properties  that says "allow turn off to save power"   as advised - Did not help. 

In device manager the HID touch screen would show up as working. (It wasn't)  Several fixes I read advised disabling then enabling the driver.  I worked but only for a while.  Re-checked the Device Manager - now HID Touchscreen is dimmed and properties tell me the hardware is not connected!  There is no option to re-connect.   

I shut the computer down - too frustrated to continue.  Next day I turned it on and touchscreen worked for a second and stopped.

Now the Device Manager does not even show the HID Touchscreen unless I click "view show hidden devices"

I called Acer Support - they told me to do a factory reset if that didn't work (it didn't) I would have to send it in for repair.

I guess I'll have to do that.  Was Acer able to fix your notebook?

After many days of trouble shooting this problem, and deciding to send mine in for repair, I did a general search on "touchscreen problems" from Acer to Toshiba, people were having similar problems - in most cases they said their touchscreen failed after they updated from Windows 8 to Windows 8.1.  As mine came with 8.1 installed I have no way of checking.  So I would be very interested to know if Acer was able to fix yours. Please let me know. I would really appreciate it.

Thank you

The issue occurs randomly for me.  I can go weeks with no problems but then suddenly it will happen every few hours.   I can usually fix the issue by putting my computer to sleep then waking it up.

I depend on my laptop for school so I've been reluctant to send it in.  I just finished classes so I plan to send it in for repair in the next week or so.  Thankfully, the laptop has a 1 year warranty.
