X1 Carbon 7th (20R1) Preboot Fingerprint Authentication not working after BIOS and FP driver update

2020-12-07, 8:12 AM
Recently updated my X1 Carbon 7th (20R1)'s BIOS and fingerprint reader drivers to the following.BIOS: Thinkpad BIOS Update - 10 [64] -1.30
Fingerprint Driver: Synaptics Prometheus MIS Touch Fingerprint Reader Driver (Windows 10 Version 1809 or later) - 10 [64] -

Used to have Preboot (pre-desktop) fingerprint authentication activated.

Once I updated said BIOS and driver, the time between the Lenovo logo appeared and the preboot FP scan request became very long (around 45 seconds or more). Before the update, this took around 1-2 seconds.
Also, even though the a FP scan request appeared on screen, the FP reader did nothing. Instead, I was forced to press ESC and type in my PIN number.
Already tried to roll back the driver and also resetting FP data from BIOS and also from within Windows and then reactivating everything.
In fact, when I tried to setup the preboot FP scan from the BIOS and rebooted, the laptop got stucked in a black screen after it displayed the Lenovo Logo. Nothing worked: no BIOS, no booting sequence, no diagnostics, (F1, F2, F3, ... F#, etc...)
Because of this, I had to open the laptop and physically disconnect the FP reader, thus forcing the system to ask me my PIN and then turning off the predesktop FP authentication.
BTW, fingerprint scanner works fine with Windows 10 Hello.
So far, I've had no luck in making the FP reader work for the preboot (predesktop) authentication.

Any help is highly appreciated!
