fingerprint reader stopped working on Ideapad Flex 5 after 1803

This problem has been reported several times before, but no answer whatsoever 


The fingerprint reader stopped working, apparently after a windows update upgrade


I have tried EVERYTHING there is, from uninstalling and deleting the driver files then reinstalling, downgrading the drivers, rebooting, upgrading, updating chipset, video card and display drivers, updated BIOS, etc. etc. etc. and the best thing that can happen is for it to work a couple of times and stop working again... it is a less-than-a-month-old computer and it seems  MANY users are having this problem....

I already ran Lenovo Diagnostics tool, Lenovo system update tool, Microsoft's windows update and have latest definitioins for everything, Microsoft trouble shooter recognizes the problem but can't fix it.


the only thing I haven't tried is downgrading my windows 10 to a previous version...




Lenovo Ideapad Flex 5 

Model 81C9

Processor Intel Core 17-8550U @ 1.80GHz

Operating system: Windows 10 Home 64-bit  Ver. 1803


Synaptics WBDI driver version: 5.5.2613.1050


Intel(R) UHD Graphics 620 ver.


BIOS version 4QCN43WW(V2.07)


Thanks for any help I can get to solve this annoying situation

It is an obvious problem with all of the posts and I guess you're not going to fix it? This computer is 2 years old and almost full on the HD capacity. Up until now, your support sucks and I'll definately look at alternatives. after this long and still no workable solution, iyt apepars you don't want return customers.
