Asus x202e touch screen issues

I got my Asus Vivobook x202e about two days ago after ordering it from Amazon around the 4th or 5th of April 2013. Upon start up, several times I noticed that sometimes there is a circular pattern on the screen. It appears on start-up about half of the time and always in the same spot.



Screen issues: When it appears the touchscreen is a pain to use. In the start menu, when this circle appears, scrolling from left to right makes me zoom in and out of the tiles instead of going from left to right and I don't get inertial scrolling. Switching to desktop mode and back to start up menu would resolve the issue, sometime. Sometimes it disappears on it's own after a few seconds, sometimes it stays there for much much longer (+30 minutes). When using desktop mode it limits my touch capabilities to only scrolling up and down on a webpage. When I touch the screen (anywhere on the screen) while the circle appears, a similar circle is produced. When I touch something like the minimize button on Google chrome the botton stays highlighted but doesn't actually minimize. Also when the circle appears when the lock screen is on, the screen begins to shake like someone with Parkinson's Disease has their finger on the screen. (Sorry if that was offensive but it was the only way I could give a good visual of the problem)

Cursor issues: During this time my cursor moves itself to the spot and behaves erratically (moves from left to right and in circles) but it usually last for a few seconds and my touch pad is fully operational and doesn't give trouble. I guess I should also mention that most of the time when I have touch screen issues the mouse works just fine.

Troubleshooting: Although it's disappointing that my new device isn't working as it should, I am enjoying the troubleshooting process. The last time I troubleshooted a BSOD issue on my last laptop and learned A LOT about hardware components and their functions, IT terminology and I'm actually glad I had that problem; I'm much less ignorant now. I realized that I enjoyed the process of troubleshooting, theorizing about what's wrong, collaborating with others about what's wrong and that I will only be happy unless I have a job where I am surrounded by computers and computer enthusiast (Got accepted to a 4 year Software Engineering BA program that starts in October). Anyway, this is what I've tried so far:

1. Windows Update - The notebook is up to date with all Windows 8 updates.

2. Triggering the event - I've noted that it's much much easy to trigger the event when I try to pinch-to-zoom along the vertical path of where the circle always appear ( from top to bottom of the screen). When I pinch to zoom anywhere right of that "line" it's much harder to trigger the touch screen problems. As I said, sometimes it appears on startup and sometimes it's triggered.

3. I've tried updating the drivers using the Windows driver update options(device manager) but it always says that my drivers are up to date. I've tired searching the Asus drivers site for driver updates but I honestly don't know what drivers to install that could potentially relate to or resolve the issue. Some updates obviously won't help the issue, e.g. Wireless Drivers, Audio Drivers, etc but I'm not exactly sure what drivers to update. ASUSTeK Computer Inc. -Support- Drivers and Download X202E

General: It doesn't limit my ability to troubleshoot, web browse, type. For the most part the computer is still functional especially when I use it in a traditional manner (touch pad and keyboard). However using touch drives me crazy.

Questions:

1. Would doing a factory reset help resolve the issue or is it a waste of time?

2. Would installing a different version of W8 e.g. W8 pro potentially resolve the issue?

3. If I install Ubuntu or another OS and the problem is still there then does that 100% confirm that it is a faulty hardware issue?

4. What drivers are responsible for making touchscreen function?

5. Can I use substitute drivers instead of manufacturer drivers? (sounds like a bad idea)

6. What software tool can I use to resolve the problem, if any?

7. Does this look like a calibration issue?

6. Is this a BIOS issue?

I should add that I want to do my best to avoid sending it back to Asus. I live in Trinidad and Tobago and I need my computer to get some very important stuff done. If I send it back for repairs I could potentially not have access to a computer for a while and I'm already behind schedule.

 

I have the same problem, occurs sporadically.

Had it happen to me now when I plugged in an external set of speakers while playing Civ 5. That brought up the Select headset or mic-popup and messed things up, but previously I've had it happen under other circumstances.

Rebooting, logging in/out, changing power preferences etc didn't help, but when I shut down the computer and started it up, the problem was gone. Would really like to know the root cause - probably a driver issue... (?)

Just struck me that I do have a Logitech Wireless mouse receiver plugged into a USB port - I wonder if that could be related? Will look into that the next time the problem occurs...

 

i too am having the same issue with my asus s200e touchscreen would love to hear from anyone who has resolved this problem

 

I was experiencing the same issues after a windows 8.1 upgrade. I ran the system refresh and reverted to windows 8. My touch screen is working completely again so this almost definately isn't strictly a hardware issue. If you set a restore point before the upgrade you should be able to easily revert. I didn't, so I had to reinstall/setup everything (although it only took 15 minutes) and, worst of all, I had to redownload and install 90 windows updates. I still haven't completed that process as it has been taking hours.

It looks like the touchscreen itself is supported through some general driver as it is registered as an "HID Compliant Touch Screen" in the device manager (removing this driver will stop the touch screen working complately). So there is still a chance that there is a design/common flaw in the touch screen in which it doesn't act as a true HID Compliant device and windows 8 simply didn't expose the issue... the previous statement is mostly a disclaimer, it's probably a flaw in windows 8.1.

 

I bought a refurb X202e which started exhibiting same issue after a few weeks. Sent it in to Asus, they claimed to have fixed it, but it persisted. Sent it in again, they replaced the screen altogether -- that did the trick.
