Default How I fixed my lenovo ideapad a1's unresponsive screen

Bought the A1 as birthday present for my 8 year old daughter.

She has been using it non-stop until the battery dies.

While charging, she got impatient and turned it on, then the screen stopped responding to any touch. Turning it off by holding the power button, then turning it back on didn't help.

I called lenovo tech support, told me the same, turn it off by holding power button for 10 seconds, then power on, waisted 2 hours, they wanted me to ship it back to have it fixed, then shipped back to me ! I said, no way, this is her birthday present, so tech support guy suggested I call sales and have it refunded.

This morning I decided to try something, after powering it off by holding power button for 10 seconds, I pressed the volume + button and power button simultaneously, it powered up into some restore screen, there are a few menu options, i.e. restore to factory settings, the last was recalibrate touch, I used the volume buttons to scroll through the menu, then used the power button to "select" the recalibrate option, it said don't touch the screen, took a few seconds and powered off.

I pressed the power button until you feel the gsensor, then let go, tablet powered up and the screen is working again !

Hope this helps anyone else having this issue.

Do an update and it should solve the problem (Settings -> About Tablet -> System Update)

No, that displays: Your system is currently up to date.

The unresponsive screen issue is not solved with the touch calibration or the update, at least in my experience. I have even gone to factory reset and the issue keeps happening. I did root the phone, and the screen issue only occurs once a week or so now. Lenovo really has to issue another update to fix the many common issues people are having with this tablet. The XDA Developers website has information on how to root the tablet. It is very easy.

I have some what determined what is stemming this issue but have not figured out a fix yet. While charging my 2 brand new A1s, they become unresponsive after no use and then are unplugged. If I plug it back in, either one, they become responsive again. Unplug nothing, plug back in full control. Turn it off, unplug, do touch calibration and it will fail, but after reboot it is all ok. If I leave it in standby for too long I get nothing again unless I plug it in. The 2 units I have are updated fully, 1 is rooted and another is not.

My NEW A1 was suffering from the virtual keyboard being almost unusable when pressing near the edges of the screen. The recalibration technique quoted above seems to have corrected the problem. I am absolutely sure response speed and location sensing greatly improved by this recalibrating method. FWIW, my bad sensitivity problem did not get worse after adding a screen protector (same problems happened before screen protector as after the screen protector), and, the new calibration includes the screen protector - location and sensitivity is now better than ever.

I wonder if every new A1 should have this calibration...?
