I've bought 5285 from ebay - refurbished and I have a problem with getting fingerprint scanner working. I wanted to used it to log in to windows - but in 'sign-in options' windows hello tell me that 'windows hello isn't available on this device'.

In device manager, I have 'biometric devices - control vault w/ fingerprint touch sensor' installed and updated to most recent version, the same with 'ControlVault Device - Dell control Vault w/ fingerprint touch sensor', installed and updated to most recent version.

Have anyone get it working, the system is windows 10 pro, 1709 version, all windows updates installed.

I've tried to contact dell support but have only basic warranty, been told that it's not a hardware problem, software team tried to charge me £50 for help and told me that my table doesn't have sensor, but i clearly see it on the cover

please help anyone?
