Windows 10 devices with a fingerprint scanner can sometimes face a strange issue where after waking the system from sleep, the scanner doesn’t recognize the finger. Subsequently, you cannot use the fingerprint scanner no matter how many times you try. Simply put, under certain circumstances, the fingerprint scanner is not working after sleep in Windows 10.
For a vast majority of Windows 10 users, the fingerprint scanner will work perfectly fine. However, due to some driver issues and scanner settings, the fingerprint scanner might be asleep even after you wake up the system from sleep.
