SF314-510G - Fingerprint Sensor not recognized in Windows ( not showing up in Device Manager too )

I own a Intel i5 11th gen variant of SF314-510G. Fingerprint sensor doesn't get recognized in Windows settings as well as Device Manager for me



And there are no failed hardware detection in Device Manager too. I tried installing the official drivers again as below:



But still, it doesn't change anything. What might be the problem here ?

    And I tried degrading to Windows 10 too with a clean install after a Memory wipe. Installed all the recommended drivers for Windows 10 from Product page. But the above issue still persists

    Kindly do the power drain, bios defaults and then try to install the finger print driver..

    Note: Before installing the finger print driver, try to install the i/o drivers, chipset driver first.


    Doing the power drain and bios defaults will really help.  Kindly follow the steps given below:


    Turn off the laptop. Disconnect or unplug the charger cable, devices or any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, you can find a  pin hole. It is a tiny hole. You can a find a battery symbol indicator next to the hole. It is like a + and - sign symbol as though somebody is trying to shift the battery out. Insert the pin on to the hole for 30 seconds. Remove the pin. Flip the laptop. Connect the charger cable, turn on the computer.  Only on laptops where the battery is inbuilt you can find the battery reset hole on the back of laptop.


    If you don’t find a pin hole on the back of laptop then you might be using removable battery. There is no need to unscrew anything to remove the battery.  Turn off the laptop. Disconnect or unplug the charger cable, devices and any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, please look at the top or bottom depending on the way you look at it. You can find a long door. It is a battery removable door.  Just below that you can find a latch.  If you move the latch you can remove the battery door. Once the battery is removed, flip the laptop. Open the top cover, press and hold the power button for 1 minute. Connect the battery back on the back of computer. Connect the charger cable back and then turn on the computer. 

     

    If you don’t see a reset pin hole on the back of laptop or if you are not able to remove the battery (if it is inbuilt) then please unplug all the cables and devices out of laptop.   Hold the power button for 1 minute.  After releasing the button you should wait a while before plugging in power. Just because the button has been pressed doesn't bleed off all the residual electricity on the motherboard. Wait 15-30 minutes before plugging in power. Then once power is connected wait for a full battery indication before turning the system on. That allows the battery to fully reset it's internal statistics.

     

    Connect all the cables back and restart the computer.  



    While turning on the computer, tap f2. It will go to bios. Press f9 once. It will show load bios defaults with a yes or no popup. Press enter. Popup screen will disappear.  Press f10 once. It will show save changes popup with yes or no. Press enter. Computer will restart and it will load into windows.   


    Now try to install the i/0 driver, chipset driver and then the finger print driver from the link given below

    I tried everything step by step as you suggested. But still no. I don't see my Fingerprint scanner in Device Manager yet.

    There will be a section in Device Manager called Biometric Devices. It may be that the internal USB hub isn't being initialized and the fingerprint sensor is on that hub, so it wouldn't be seen as installed. It also might be that the wiring that connects to the MB has loosened. Since you are still in warranty I'd contact Acer support about it.
