ThinkPad P51 Fingerprint Cannot Unlock

2021-04-16, 9:32 AM

ThinkPad P51 @ Windows 10 20H2.

Fingerprint unlock works when cold booting, but wont work when unlocking from sleep or lock.

When I say not working, it means the sensor can recognize my finger (light turns green when I put the right finger and turns orange when I put the wrong finger on it), and Windows does show the windows hello on the unlock screen, but cannot unlock and go into my desktop screen. I have to type my PIN code to unlock it.

Does anyone has the same problem? How to fix this?

Thank you!

Hello XMFENG,

 


Welcome to Lenovo Community

May I know when did this problem started?
Have you updated the BIOS and drivers thru the support site?
I suggest that you share the machine type model / MTM (ex. 81C70000RK) from the sticker as it would help us detail more about your machine variant.
 
Update us soon as convenient

 


Regards, 
Lorenzo_Lenovo
