Power-on or Hard Drive Fingerprint passwords not accepted using External Lenovo Fingerprint USB Keyboard - ThinkPad T420, T420i, T420s, T520, W520, X220, X220 Tablet
Symptom

Users are unable to use some versions of the External Lenovo Fingerprint USB Keyboard to successfully authenticate Power-on or Hard Drive passwords. When the fingerprint is swiped, the entry is validated, but then rejected as incorrect. Both Power-on or Hard Drive password are impacted by & passwords are required to allow the user access to the system.

Enrollment and using the device for Windows-based passwords is not impacted, nor is using the integrated fingerprint reader.

To know whether your USB fingerprint keyboard will work or not, refer to the label on the bottom of the external keyboard. Those keyboards with "Fru P/N" and/or "P/N" such as 57Y4780, 41R008, and 89P9000 will experience the issue with the affected systems.

Those keyboards with "Fru P/N" and "P/N" starting with 03X, such as 03X8001, will not experience this issue.
