Lenovo Yoga 720 15 - Fingerprint reader issue - WBDI synaptics driver - Windows Hello

Hi, I have the Lenovo Yoga 720 15 IKB 80X7 (4K display), since many days ago, I'm currently posting this on 7-20-2017, the fingerprint of my laptop stopped working so now In the windows hello sign in menu it shows a message in which it says "Windows Hello is not available on this device", the fingerprint option doesn't appear there anymore.

When I check the issue on the "update device drivers menu" an exclamation mark appears next to the synaptics drivers WBDI, in the section of biometric devices. When I click on it to see more information it appears this message:

 

"This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

{Operation Failed}
The requested operation was unsuccessful."

 

I show you in the picture the information I get in the driver tab. I do not have the option to roll back the driver so I can't make it work again. I checked and it is the last driver available so far but it doesn't work. 

By the way I have the same exclamation mark and the same message of error in the driver "system interface foundation driver", code 31..., is there any link with it?

I've already re installed windows twice through the option "reset this pc" from the configuration menu, one without deleting my files and the other removing all, but I still had the same issue with the fingerprint reader since the beginning of the new start, it didn't work. Does anybody have the same issue and a solution?

Thanks in advance

Hello

Thanks for using the Lenovo forums.

Try to download the Chipset drivers for the unit from the support page.

 

Make sure to reboot after an update on the unit.



 

Also, try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

Hope this helps, let us know how you get on.

I have the same problems. Had this computer for two weeks and suddenly the fingerprint reader stopped working and is shown in the Device Manager as a Code 45.

 

Any suggestions?

Hey, were you able to solve it? I have the same issue on my pc. After a Lenovo Update, the fingerprint reader just stopped working and I'm pretty sure it's an error in the driver, because it says there is an error in it. 

Does anyone know where I can download the older drivers so I can downgrade mine?

I also have the same problem with the fingerprinter of my Yoga 720-15IKB:

"This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

{Operation Failed}

 

I installed the lastest fingerprint and chipset drivers from Lenovo's driver site, still the problem persists.

 

Please support!

I now got it working by setting the "Intel SGX" value in BIOS from "software controlled" to enabled. After the next boot, some SGX drivers got installed automatically by windows update. Then the fingerprinter worked. I had no idea that Intel SGX is needed for the fingerprinter to work. Hallelujah...

I've had this issue twice - i'm not sure how to update the BIOS myself but more importantly is that something that regualr folks should be doing ? (if it is - is there a guide somewhere ? )

Hi, it didn't work for me. After reboot it remain the same. Did you get any message or notification to update some drivers after you enabled INTEL SGX? cause I didn't get anything, so I just launched my software to get drivers updates: driver max. It didn't work neither. This week I got a notification of an available update to the driver for the fingerprint reader, after installing it it no changes neither... **bleep** with this driver.... it was one of the most interesting features of this laptop and doesn't work, any other suggestion?

Hi man, to update the bios of your laptop normally you have to go the website of the brand, look for software for your product and then just download what you need. This is also useful when you format from zero your laptop to install windows again or you just install a new operative system such as linux. At that moment you'll need the drivers to make work your specific model with the operative system.
To update the bios just go the lenovo website, download the software for your machine, in this case download the bios software and after double click on the .exe file and it installs automatically.

For instance these are the drivers for my specific model, there I download the bios. If you don't have 4K display your model may be different and you'll not be able to install these drivers, windows will tell you anyway.

Re: Lenovo Yoga 720 15 - Fingerprint reader issue - WBDI synaptics driver - Windows Hello

Hi jsecu19, after setting the SGX value to enabled, the Intel SGX drivers installed via Windows Update automatically - I did not have to confirm anything. I guess there are many possible reasons, why the fingerprint may not work. So you already set the Intel SGX at Bios to "enabled"? If I were you, I would try to uninstall all with the fingerprinter associated drivers via device manager. This is the fingerprinter itself under "biometric devices" and under "software components" there is the "intel software guard extensions" (SGX). Then I would download the latest fingerprinter and SGX drivers from Lenovo, install them and restart twice. If is still doesnt work, I would setup the notebook totally new and make a clean Windows install. If this still doesnt work, I would send it to Lenovo for repair, of course.
