Yoga 900 touch screen not working

Hi,

 

My screen suddenly stopped working as touch screen (it works in normal mode with the screen and the touchpad). The first times I restarted the computer several times until it worked, also to connect to the network seemed to help; however this time didn't do the trick. I used Lenovo Solution Center, and it didn't show any problem. I checked and updated the drivers in the Lenovo Yoga Mode Control and it seems I'm up-to-date. Now it doesn't want to change to tablet mode automatically anymore, neither to switch the screen to portrait.

 

Thanks in advance for the help.

Hi there, ADW            -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

Press Windows + X
2. Select Device Manager.
3. Find the Touch screen driver under Mice and Other Pointing Devices > USB Touchscreen Controller (A111).  You're going to uninstall this and check the box that says "Delete the driver software for this device".
4. Restart your computer.
5. Re-open the Device Manager, and confirm that the Touchscreen is now listed under Human Interface Devices. 

 

Update us how it goes.

 

 

 

 

Regards,

Hi Shashi,

I went and looked but there is no such a driver (see pic attached). Actually I tried to look before for something similir but didn't find it.

Looking forward to your instructions; thanks for helping.

There are not touch screen drivers in my computer. For more than unistall and restart the computer, the drivers don't show up (HID, Mice and .., and USB controllers).

Re: Yoga 900 touch screen not working

There could be a chance where something to wipe the touchscreen calibration data.

 

On a clean install or refresh of windows, using the calibration tool for the first time will bring up a more detailed calibrator -- it has 16 crosshairs, four in each corner that you have to touch to calibrate the screen. 

After the first calibration, any repeated attempt at calibrating the screen brings up a screen calibrator with only four crosshairs -- one in each corner. 

After each restart, the computer defaults back to the first advanced calibration.

 

Update us how it goes.

 

 

 

 

Regards,
