Re: Flex 14 ideapad touch screen not working Windows 8

Hi there, DR –

 

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

 

- Press Windows+X.

- Select Device Manager.

- Find the Touchscreen 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".  Don't worry, it won't blow up your computer.

- Restart your computer.

- Re-open the Device Manager, and confirm that the Touchscreen is now listed under Human Interface Devices.

 

Update us how it goes.

 

 

 

 

Regards,

Thank you for your care and reply.

Unfortunately, I can not find "USB Touchscreen Controller" under "Mice and Other Pointing Devices"!

The only item found is "Lenovo Pointing Device"

What can I do further?

Thanks in advance

In regards to your issue with Flex 14 touchscreen works fine until a USB device is used/installed, and thereafter works sporadically. You will require to send your machine to our services team. A firmware had been set to address this issue and can only be done by our service team. The reason for this is because the firmware cannot be applied by end users as it requires disconnecting a few cables inside the system. You will require to contact our service team for the assistance.

 

Update us how it goes.

Re: Flex 14 ideapad touch screen not working Windows 8

Dear

Shashi_Lenovo

This is not the case I described!

I haven't said that <<Flex 14 touchscreen works fine until a USB device is used/installed, and thereafter works sporadically>>

I said that is suddenly stops acting as a touch screen, and I did not find the "touch screen" under Mice section.

 

Any further help.

 

Thanks in advance

Clean the surface

System Restore (search – System restore – setting – Create restore point – System protection tab - System restore)

 

Touch Calibration (control panel – Tablet PC settings – Display tab – calibrate)

 

Enable the Touch Function (like below)

  • Power on and boot into windows
  • Call administrator command prompt

                Press Win + X

                Select Command Prompt (Admin)

  • Shift+Fn+F10
  • Enter command and return:

               bcdedit /set testsigning on

 

  • And enter reboot command and enter:

               shutdown –r –t 0

  • Check the Pen and Touch Hardware availability in system properties.

      If Pen and Touch Input / HW is not avl means

  1. Touch cable not connected properly
  2. Touch panel issue

Update us how it goes.

Re: Flex 14 ideapad touch screen not working Windows 8

Thank you all for your help,

Unfortunately, the issue was not solved!

I sent it to Lenovo service center in my country,

They said that they can fix it but the cost is almost 700$ which is a joke, not an offer! as the new laptop is fairly less than this price!

 

Thanks Lenovo Smiley Frustrated

Re: Flex 14 ideapad touch screen not working Windows 8

I have Flex 14 Ideapad S100 and Windows 10 with latest updates and I encountered the same problem suddenly a few days ago. I recovered my computer turning back to an image taken by Win10 two months ago, it did not help. Some how next day in the morning it worked only for a few hours then stopped working again. So I think it may be a (common) hardware failure. I hope it is a software/driver failure and this problem will be solved soon by Lenovo.
