The "internal" keyboard (in the docking station for this tablet PC) is not working in the POA on a Lenovo Helix.
The device has been added to the blacklist for volume-based encryption.

The root cause is, that the keyboard does not work in FreeBSD (even not in the latest version), so it`s actually not an issue of SafeGuard Enterprise but has an impact on the POA which is based on FreeBSD.
