I have a Lenovo 700 running windows 10 64 bit.
Recently the screen went black and I had to reboot the laptop which at first wouldn't reboot but eventually did. This happened twice. There was nothing in the event in log other than me shutting the laptop down unexpectedly.
Since then it has been stable. However, the touchscreen no longer works.
System information states that there is no touch input. See image.
Device manager for human interface looks like this.
The only error in the device manager is a usb error which i can't work out. see image.
Things i have tried;
1. rebooted serveral times.
2. Run trouble shooter - detects usb error but once you select that it says all is ok
3. Checked event logs
4. Unistalled usb device
5. Uninstalled HID-complient Vendor defined device
Last update was 2nd of March 2019 for KB4023057. Which improves disk cleanup.
Tablet mode does not enable touch screen .
Thanks to anyone who has any ideas on how to restore it or what the issue is
