I recently got X1 Yoga gen 4.
From the start i noticed after I wake up the laptop from from Sleep Mode (Windows 10 pro) the fingerprint is not working
I must choose either password or pin in order to log-in to windows.
a) fresh reinstall os from usb-recovery from Lenovo
b) re-install drivers from fingerprint
c) disable the option "Allow the computer to turn off this device to save power" in device properties
This issue is not happening if i turn off - turn on my laptop. Moreover, it happens only if my laptop goes into "big-sleep" (shows the lenovo logo after wake up).
Solved! Go to Solution.

Hi groban1! Try installing the updates through the Vantage app. Run the update and install all detected updates then check if the issue has been resolved.
If the issue is the same, kindly send to us the system information. You can get it by typing the word msinfo at the search box at the bottom left side of the laptop.

I have the same issue. When timers cause it to enter and exit sleep mode during the day, fingerprint reader works find to authenticate after waking up. However, if the Lenovo Vantage Smart Power Settings cause it to hibernate after active hours are over and then switch to sleep mode when active hours start time says it should, the fingerprint reader is inoperative for the first authentication. After that, the fingerprint reader is good for the day, until the next time Smart Power hybernats the system over night.

Thanks for posting your solution.
Did you install the new driver from Lenovo Vantage, Windows 10 Device Manager, or by going to Synaptics' web site?
I did a "Check for Updates" in Vantage, and the driver wasn't listed.

Thanks again. I'm sorry I didn't think of this before, but I went to Device Manager and I do have the driver version you posted: 184.108.40.2065.
Apparently, it was installed when I configured the machine, because the date of the driver is the same date I configured the machine. Interesting, because your post shows a driver release date of 01/19/2020, and my Driver date is 12/19/2019. Maybe mine is beta or pre-release.
I did notice a Power Management tab in Device Manager Device Properties with a checkbox that says "Allow the computer to turn off this device to save power". I will play with that setting and see if anything changes. It might take me a few weeks because I'm tied up with year-end, but I will post back when I have results.
