Kernel-Power Event ID 41: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Hello,  Currently we are seeing this issue with a couple of our Lenovo T420s laptops with a Solid State Drive.  ruffly about 10 or so.  The Reboots happen randomly and do not create a dump file.  We have contacted Lenovo and they are not sure why its happening.  Since this Crash I set it for Minidump this did not work my next steps will be to Disable Automatic restart on System Failure to see if it brings anything up.  I am also looking at using Procmon to dump to a file as well.  If anyone has any other ideas please let me know.

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
