Hello skdhpdv6_3130s,
Thank you for posting on the HP Forums.
I understand you are experiencing issues with your fingerprint reader on the notebook. I apologize for the late response, but I will do my best to assist you!
It took me a while to find this information, but this model best supports the Validity Fingerprint Sensor Driver. I would try installing this driver and seeing what happens. If this does not help you, I will provide a document on troubleshooting fingerprint readers in Windows 8 (8.1). This document will help narrow down the issue, and troubleshoot specific issues, such as driver and software conflicts: Troubleshooting a Fingerprint Reader (Windows 8)
I believe trying these steps will resolve the issue. Please post your results. Thanks again for posting on the HP Forums. Have a great day!
Mario
