    I have an Lenovo Ideapad 720s, the 14 inch version.

    The Synaptics WBDI (fingerprint reader) doesn't work for longer then a day...

    Issue first started on Windows 10 1803, when I closed the lid without shutting down the laptop, the finger print reader would not work when I opened the laptop. If I rebooted it, it would work again.

    Then I updated to 1809, and at some point later, reboot would not enable it again.

    Now i'm on 1903, and now when I uninstall the fingerprint reader few times, it will work for 1-2 reboots, and then stop, then if I uninstall\reinstall the fingerprint reader 5-10 it will work again for 1-2 reboots.

    I have the latest driver available on lenovo website.

    It showing code 10 in device manager.

    I tried with intel SGX enabled and software controller in bios, same issue.

    Tried about 7 out of 250ish...

    2 of them got rid of the code 10, but fingerprint reader didn't do anything.

    1903 is very buggy. I never got around TPM driver code 10 error. Dunno why it happens. I disabled it entirely.
    Do you have Intel MEI TPM along Synaptics Fingerprint sensor? You can check using tpm.msc
