Yoga Thinkpad 460 Touch screen not working

[einar_100]

Hi,
I suddenly noticed that my touch screen is not working. I have tried to update driver for HID-compliant touch screen (however best driver was alread used). Also tried to disable/enable the device but still no function. I checked the "Events" for the driver and the last event was "Device not migrated" with the following message:

"Device HID\VID_056A&PID_504A&Col06\6&2fac5222&0&0005 could not be migrated.

Last Device Instance Id: {DEA5AE2A-D1FD-438A-A091-CBD484788436}\Vid_0000&Pid_0000\5&18534b98&0&02
Class Guid: {745A17A0-74D3-11D0-B6FE-00A0C90F57DA}
Location Path:
Migration Rank: 0xF000FFFFFFFFF122
Present: true
Status: 0xC0000719"

The pen driver seem to work though. I noticed that outside the visible area on the screen there is a small crack in the glass. Can that cause the touch screen to not function? 

Regards, 

Torsten

I have exactly the same problem Event description " HID compliant touch screen could not be migrated"

I haveFlex 5-1570 (Type 80XB) Laptop (Lenovo) - Type 80XB 

Detail:

Device HID\WCOM50E8&Col01\5&11e08167&1&0000 was not migrated due to partial or ambiguous match.

Did you resolve this issue? What did you do to solve it?

Thank you.

The pen and the finger-touch are 2 separate devices, so it makes sense that 1 would work.  The little crack means there is a break in the matrix that handles finger-touch so that is probably the reason.  The pen digitizer is behind the panel.

Please help to fix my touchscreen. No physical damage. Stopped working completely.
