Thinkpad T540p Fingerprint Sensor Randomly Stopped Working!!?

Yesterday out of nowhere my fingerprint sensor just stopped working, doesn't turn on, doesn't show up in device manager, I have disconnected it reconnected it nothing... Lenovo Vantage no drivers... I need to know what is going on. Someone, please help.

That is strange. They recently released an update for the biometrix and wonder if that is the culprit. If it doesn't show up in device manager, I have no idea how you can roll back the driver.

Perhaps manuall re-applying the Synaptics WBDI - SGX driver update?

 

Downloading the "old" non-SGX and applying that driver?
