Chosen Solution
Hi, I’m having issues with my Asus tablet running Android Lollipop. For the past few months, the touchscreen would stop working momentarily, then everything would come back to normal after a few restarts. It was more likely to happen when the tablet was charging though. At some point I found a weird hack that was plugging the tablet for a second every time it happened. Now for the past few days, this would work and the tablet is now useless without its keyboard. I’ve read on some forums that the Battery Saver app could be the cause. Indeed I noticed a bug with it because every time the tablet was charging I would get a notification saying that an app was drawing too much power, but the Battery Saver app would crash every time I tried to open the notification. Last night, I disabled the power saving mode and rebooted the tablet (as suggested in the forums) but it didn’t do the trick. This morning, I tried to reset the tablet both via the settings menu and recovery mode, but then touch screen is not working. I also tried to “swipe cache partition” but none of this would work. Is there anything else I could try? I’m not sure if it’s a hardware or a software issue, but as far as I remember the tablet has not received any impact in particular and there’s no scratch at all on the screen. Thanks
Actually, my cable solution only worked for a short period, then it stopped again. So I tried the pigtails to the screen, as per Rod H’s post. But again, it still only worked for a week or so. Then I had a think about the connections to the screen: they come into the same small sub-board as the USB connection, and both the USB power/signals and the touch screen signals go through another pig tail connector to the main board. I thought that it is possible that the movement of the plugging and unplugging of the USB (as per Andre’s original post) might disturb the connectors. So I reseated the pigtail connector going to the main board as well. That was over a month ago, and the problem has not come back. I hope this works for you as well.
See my message in one of the other threads about the same issue, same model
I just found in another post that the digitizer cable can come loose or detached from heat
I also found this issue with a TF103C tablet. I opened the case and re-seated the screen pig-tails and the screen became fully responsive. Then some time later the screen was again unresponsive. I’d read that a static buildup on the screen can cause the screen to become unresponsive so I opened the back but this time just touched the screen pigtail connector rather than re-seating the connector. Again the screen regained its touch control. I think there’s something to the static build-up theory and will use that fix in the future.
where the finger points
Well, I swapped in a digitizer/screen (unplugged the old one and plugged in a new one that I left on the desk) and it made no difference on mine
Hello. I fixed this by: a) Powering off b) Opening the back cover c) Disconnecting the battery for about 10 secconds d) Re-connecting the battery e) Restarting. Thanks. BC
Hi. I had this problem too. I bought this tablet 2days ago as used. And it started no responsing after first charge. Result from reading different forums - disconnect flex cable from docking connector inside tablet. Also re-connect, just for sure, touch/screen double flex cable (on right side down under silver tape). I am using it as a tablet without docking to keyboard. Therfore such solution.
Connect keyboard via keyboard slot or via USB and turn off Power saver in Settings and touch will work again
