Servicing Device Please Wait

Domain network no internet access.  Used in manufacturing environment to keep track of production.

HP t520 Flexible Series TC  x64

4.0 GM RAM

Windows Embedded 8 Standard

Today it apparently rebooted and instead of the normal "Please Wait" , it showed a "Servicing Device / Please Wait" and never booted into windows.  Hard reboot and it does reboot with the normal "Please wait" screen and then it does boot into Windows.  The other IT person has never seen the "Servicing Device Please Wait" screen either..

Memory and HD check on restart and no errors.  Nothing in event log.  Tried to google for the "Servicing Device Please Wait" and could not find this anywhere.  Disconnected all devices (label printer and bar code scanner) and connected new mouse / keyboard and a different monitor and thought it was working fine but when I left my desk after it was running fine for 1-1/2 hours and when I came back to the same screen (Servicing Device / Please Wait) and it never rebooted into windows an hour later.    Did a hard restart and it had the normal "Please wait" screen and booted into windows normally.

Have 30+ of the same PC running the same software and have never seen this happen before.  Appears to be a hardware issue and still troubleshooting it but where does the "Servicing Device Please Wait" come from?  Has anyone seen this before?  Any ideas what the issue is?

Further investigation this is a Microsoft Embedded screen saver for the Windows 8 Embedded OS

Mouse movement or keyboard entry does not stop this screen saver - must hit the escape key.

Do not know if a windows update or a user did this (many users have access to the PCs at any given time - a business requirement)
