Hello, thank you for reaching out to Microsoft Q&A.
Have you previously used the fingerprint scanner feature on this device?
When checking the technical specifications of the ASUS TUF Gaming A15 laptop on the ASUS website, it does not indicate that the device has a built-in Windows Hello fingerprint scanner. Since this model is specifically designed for gaming, it appears to lack both biometric (fingerprint) and IR (facial recognition) capabilities.
If my understanding is incorrect, please type msinfo in the search box on the taskbar and press Enter.
Then, share a screenshot of the dialog box that appears.
