Windows 10: Fingerprint Reader not working in Lenovo

Here are all the images

Fingerprint reader not working, windows 10, lenovo X200s

I upgraded my Lenovo X200s to windows 10. Since then, the fingerprint reader is not functioning. It is listed as a generic fingerprint device under the device manager, but I cannot update the driver auto or manual. I installed the Lenovo Validity fingerprint
driver for Windows 10 and used the Run: gpedit.msc route to enable biometrics, but still there is no option to set up fingerprint sign-in. Is this fingerprint reader a total loss? I haven't found any other fixes online, especially not for the X200
series. Thanks.

 

Fingerprint reader not working, windows 10, lenovo X200s

On my Lenovo Thinkpad X220 Tablet the fingerprint reader is working with the drivers which were installed by Windows.

In device manager it is listed as "TouchChip Fingerprint Coprocessor (WBF advanced mode)", with a driver from Authentec dated 27.02.2013.

As far as I remember I had to also enable biometric in group policy.

 

Lenovo X380 Fingerprint reader showing "disconnected": any fixes?

Here's my situation. I've got a Lenovo X380 Yoga with a built-in fingerprint reader. After recent Windows updates, the fingerprint reader disappeared. After digging into DevMgr, I find that this Biometric device is only viewable when I click the "Show hidden devices" option, and it shows the following status when I do that:



I've tried updating/reinstalling the drivers (and the Intel SGX device that bridges from the peripherals bus to the system circuitry apparently) and the status remains disconnected. I have not even moved the machine around much since I got it about six weeks ago. I'm inclined to believe that the fingerprint reader has failed. Can anyone offer an alternate diagnosis or a different repair strategy?

TIA for your input and suggestions.

--Ed--

PS: the unit is under warranty and I can ship it back to Lenovo for repair and diagnosis for the cost of shipment. Curiously that's about the same cost as that for purchasing a new replacement fingerprint reader. I'm wondering further if I shouldn't just order a replacement and do the repair myself. Thoughts?
