[H] Fingerprint reader

[Winterlight]

I have a Thinkpad EDGE. I did a clean install of Win10 PRO last year. 
Now I can't get the finger print reader to work right. I can setup 
the fingerprint successfully but it can never read it when I try to 
log in.  It fails twice and then tells me to use my pin. I have 
removed the driver and installed the latest available Lenovo driver 
but it hasn't helped. It has an extended in home warren and I could 
call them but it seems to me if I can create the fingerprint the 
scanner itself must be OK.. right? It must be a software or firmware 
problem... what does the collective think?
