X1 Carbon: Fingerprint Sensor does not work upon waking up from sleep mode

Although I found different threads for this or a similar issue all offered sultutions do not work for my laptop. After waking up from sleep mode (maybe forth or fifth time) the fingerprint sensor is not activated for Windows login any more (Windows Pro 10, 64-bit). Only a reboot will activate the fingerprint sensor again. I have tried everything together with the Lenovo support:

  • re-installing different drivers
  • BIOS
  • Power settings for the FP sensor
  • several new installations of Windows
  • new SSD
  • new sensor
  • new motherboard
  • new laptop
  • with and without different antvirus software

I do not have weired software installed or any unusal programs. My collegue has the same laptop except for the i5 instead of my i7 core and he has no problems. He also uses the same set of programs.

 

Does anybody have suggestions how to solve this problem?

Re: X1 Carbon: Fingerprint Sensor does not work upon waking up from sleep mode

In the meantime I found some information in the evemt logs in the administrative tools section: Every time the fingerprint sensor cannot be activated, it throws the error message "System call failed: WinUsb_ControlTransfer: 2." for Synaptics FPR. 

What does it mean?
