1. Check that your laptop is up to date with the latest driver and software from your manufacturers website.
2. Ensure that the fingerprint scanner is enabled.
3. Test the fingerprint scanner with a different user account to see if its functionality is limited to one account.
4. Inspect the fingerprint scanner for any obvious physical obstructions, such as dirt, dust, or residue build-up. If present, use a clean, dry cloth to remove it.
5. Restart your laptop and then re-verify your fingerprint.
6. If the problem persists, contact customer support for assistance and/or a possible replacement.
