Yes, I did, and I can, and I will ...
There were two errors near that same time, this morning.
The first was an error. I have copied the message I found in the Event Properties and this is it:
Error: source: event properties :
"The previous system shutdown at 5:53:44 AM on 2/11/2013 was unexpected."
------------------------------------------------------------
Critical :
source : Kernal-Power
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
