My HP Pavilion dv7 Notebook PC has recently had some issues, so I had to reset it to factory settings (Windows 7) and then upgraded again to windows 10. Now my fingerprint reader is not working, I do not have windows hello on my laptop at all, and I can\’t even find it as biometric devices in my device manager. can I do something to make it work?

Do you see any unknown devices in device manager? Make sure and check Windows update to make sure windows is up to date.
