Touch screen generating clicks without being touched

[Eran]

Hi,

The issue started a couple of months ago, with my T100.

Usually when I start up the tablet it first works well. It can continue working well for a long time, until... I am not sure what exactly triggers the problem, but usually it starts during a game of FIFA 2014 - which made me think, could it be that the more aggressive use while in gaming affects the flexible body of the tablet and damages the screen? (but clearly it shouldn't. And I am not that aggressive... I play carefully).

What happens then, the screen suddenly starts to produce "clicks", in places I am not actually touching the screen. Usually, that would happen in 3-4 spots in a repeated manner, sometime it would 'click' every few seconds, sometime it would become more frequent, clicking almost continuously like once-twice per second.

After restarting the tablet this would usually disappear - but not always. Sometimes it will restart with the issue still happening (or it will return after very short use) - sometimes it will be normal and keep working for hours before repeating.

Note - the touchscreen had been replaced after I broke the original. It was replaced at an official dealer lab, and was working fine for a few months before this started happening.

Anyone encountered this issue? Is it definitely a hardware issue, or might it have something to do with drivers or software (or even, FIFA...)? Could it be related to the screen replacement?

Your help would be appreciated! Thanks.

Welcome to the forum

Well it could be the replacement screen - but it might not be.

With Windows & the T100, the standard troubleshooting steps are...

1) Check for BIOS updates
2) Check for driver updates
3) Check for Windows updates
4) Refresh Windows
5) Restore Windows

If you work through that lot & the problem persists, then a call to Asus or your independant repairer is all that is left to you.

Hi, thanks for the speedy response... not sure about BIOS updates - do I get a notification on those (like Windows updates do)? or do I have to somehow actively look for those.

What BIOS is your T100TA currently at? If it's less than 306 then you can run Asus Live Update to get up to 306. Although 306 is a good BIOS, the current BIOS is 313 which you can get from the Asus website and run Winflash to update.

For your ghost touch issue, do you have a screen protector on your screen? If you keep the device always plugged into power, don't do that... from my personal experience on another (non T100) device, batteries left always charging can heat up and swell causing these "ghost touches".

Well, now that you've mentioned that - I don't use a screen protector but I think the situation tends to appear more often when battery is low, rather than when it's high - not sure about battery physics here, would that have an effect on heating? I wonder if the location of the 'ghost touches' hints at source of the problem. I'll try to map their exact location next time it happens.

I had an Android tablet that began having the ghost touch issues because of a swollen battery and it never recovered even when the battery level was very low. i.e. once the battery had expanded to cause the problem, it never "shrank down in size" to let the problem go away. The tablet became junk.
