No fingerprint reader after Synaptics Metallica MOC Touch Fingerprint Driver - 10  - V.126.96.36.19960 update.
Device Manager - Biomettric Devices - Synaptics WBDI(SGX disabled) shows as broken - "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)". Now I can't login with my finger!
Looks like some problems with update. Please fix it!
Solved! Go to Solution.

Hello. I have the same problem on a Lenovo P51. The fingerprint reader stopped working a few days ago. There was a Code 10 in the device manager. I updated the driver through Windows 10 and now I get: "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)" in the Windows Device Manager.
As you suggested, I went into the BIOS, but the Intel SGX was already enabled, so I made no changes. I tried to update the driver again through the Windows Device Manager, but Windows responded that I already had the latest driver. I still get Code 31 and the fingerprint reader is still not working.
Thanks for any help.

In the Windows Device Manager instead "Update Driver" press "Roll Back Driver". After that run update thru Lenovo Vantage again - it will install new driver one more time. In result fingerprint reader should work.

Well, you'll be able to see it again on the device tree, but it will remain displaying the exclamation point, going back to square one.
So with that, I'm saying I'm seeing the same problem on my P51. Can't use P51 at the moment. Has anyone reported this to the support channel? (trying avoid duplication)

Ok, found a way to "reset" the status of the device in the Device Manager (spoiler, not final solution, keep reading):
- Go to your support portal (Levono) and locate your computer model (you can put your serial number).
- Once there, go to the drivers section and search for this term: "Synaptics WBDI"
- Download the driver and install it. Next, next, next to everything.
After that, the device shows with no problems in the Device Manager. However, here's the caveat: when you try to add a fingerprint, Window's hello is unable to establish communication with the device and the dialog just vanishes (it flashes for about 2 seconds and literally disappear; must likely an unhandled exception by the driver is killing the interaction).
This is obviously not the final solution, but in my opinion will leave your computer in a "known state" so that when the fix comes, it "should" be seamless.
