Re: [720s-14IKB] Fingerprint reader Synaptics WBDI not working

Hello there, 

 

I had the same issue, wasted my lots of hours to find the soultion. Finally  I foud the guide which worked for my problem. http://forum.notebookreview.com/threads/lenovo-ideapad-720s-14-synaptics-wbdi-issue.828537/


A. Download driver from windows update catalog
i. Search for "e0eff302-9830-4775-ad1c-8ca0cb667c9f" (the update ID).
"Synaptics Incorporated - Biometric - 10/28/2017 12:00:00 AM - 5.2.311.26", 29.2MB.
ii. Download the .cab file and extract to a folder using 7zip (or some other decompression software).
If you're using 7zip, you can ignore "Warnings: There are some data after the end of the payload data".

B. Install the "full" driver
i. Search and open "Device Manager"
ii. Under "Biometric devices", Right click "Synaptics WBDI" and click "Update Driver"
iii. Select "-> Browse my computer for driver software"
iv. Select "-> Let me pick from a list of available drivers on my computer"
v. Click the "Have Disk..." button
vi. Browse and navigated to your extracted driver folder and select "sgx_base.inf"
vii. Click "Open", then "OK", "Next", "Yes", ..., etc. to install the driver.

I'm not sure if this is necessary, but I repeated steps 1.B.i. to 1.B.v., then in step 1.B.vi. to install "synaWudfBioUsbLenovoSGXProd.inf", instead of selecting "sgx_base.inf",

I unplugged and replugged the ribbon cable for the fingerprint sensor and now it works just fine. To do this you need to unscrew the the ten torque screws on the bottom of the laptop, unplug the battery cable that connects it to the motherboard (It's a bright rainbow so it's hard to miss), unscrew the three philips head screw holding the battery in, and finally fix the ribbon cable on the left side of the battery that controls the fingerprint sensor. repeat the process to close it up.

uninstall your device, don't upadte to latest driver, reinstall your old version, which is on Jun 8, 2017, version no. is 5.5.2613.1050, search your C: driver with the keyword fingerprint, you will find the old driver. The problem is caused by update of Windows, but the old version is ok.

 

This worked for me, thanks.
