That would be my thinking.  Still, one never knows.  I just find it odd
that my puter powered off and stayed off and the display was lit up on
the UPS.  Maybe one has nothing to do with the other or maybe they do. 
It's weird tho.  It makes me go hmmmmm. 

I do know that when the power blinks and the UPS has to kick in, it does
log it to the messages log file.  It also logs when power returns even
if it is only a second or so apart.  It also logs brown outs or over
voltage conditions as well.  Basically, if the UPS has to kick in for
some reason, it logs it. 

I hope it never does this again because I don't want to risk losing any
data, even tho I have a good backup.  That said, I do wish I could
figure out what happened if it does it again.  Could the new CPU I just
put in have a issue?  Hard drive be doing something weird with the
power, short out for a second or so?  Mobo be going out?  Power supply
going out?  Lots of options here.  When I do my next upgrade, I'm going
to reset and blow out all the power connectors.
