My laptop fingerprint is not working

Thank you for your message.

Did the finger print reader stop working after any particular Windows update?

The drivers are available only for Windows 8 & below. 

Download and save the chipset driver http://dell.to/2h4LrNv

The biometric driver update is available only until Windows 7, you can install the driver in compatibility mode from this link dell.to/2vLyDig   (download & save to your desktop first)

In device manager right click on the Validity sensor & click on uninstall (check the box that says delete driver) do not restart the computer.

Install the chipset driver followed by the sensor driver & restart the computer & check the functionality.

Please edit this post & remove the service tag & email address for security reasons.

It is not working when i extracted all files and installed the driver....no progress are looking....

Please check in control panel to see if you have Dell Data protection- Security (DDP-ST) tools or if you have Dell Digital delivery installed. 

If DDP ST is not installed please install from this link http://dell.to/2uaKa8W

Please complete all Windows updates, go to change pc settings -> accounts -> sing-in options -> fingerprint & then try to setup the account again.  This does not work if you have Windows 8.1 or Windows 10 installed.

Just download driver and install it on your system, after installing if you face same problem then kindly visit dell service center.
