I have Sony vaio VGN-SZ3XWP/C which has builtin fingerprint sensor but Windows does not
recognize the existence of the device that I can see - there are no entries in device manager.
I have reinstalled windows but still can't see in device manager

Any ideas??

Yeah this device stopped to work all of sudden.I got driver but i can't see biometric device in device manager. After a long search i managed to install driver but still not visible.

Or install the required drivers. If it is not presently listed in the Device Manager the driver is not installed.

You'll need to visit the Sony Web Sits and download the driver for your Model computer and the version of Windows that you are using.

Are the LED's lighting?

Did you install the Software for this device as well. With every Biometric Reader I have ever used you need to load the software and run it to set your Fingerprint/s. The Hardware types that can lock the BIOS are already activated and used from the BIOS but as you say that this isn't there you need to look at the Windows Software to do this to open Windows if you use a password.

It is possible that the device has failed I suppose but I have not seen many of these fail though I have seen several destroyed by Liquid Penetration or other ways to damage hardware. Also if the NB has been dismantled a lead for this device may not have been reattached but if the NB has not been touched and the drivers & Software is applied it should work.

I have seen a couple of these devices destroyed by a Static Discharge when the person places their finger on the reader but that is the only other thing that I have heard of that can destroy these devices.

thanx for reply. yes i did install software but whenever i went for enrolling it says no biometric device found. I have always use my laptop very carefully so i don't think that device is demage.

If it doesn't then it's not working and may have taken a Static Hit.
