Why would a pc receive a shutdown command with nobody present using the machine ?
This workstation needs to run 24 hours a day. For some reason it received a shutdown command at 3:17am and i'm trying to figure out why. It immediately received a startup command right after at 3:18am. The only event I found in the event viewer was "kernel-power 109". Any ideas?
kernel-power 109 It looks like it had a hardware problem, or there may have been a power failure. However it looks like it had a hardware issue and restarted. Updates would give a different message.
By the way, since the machine needs to run 24 hours a day, I assume it is plugged into a good UPS.

Could be a virus, or somebody messing with your head, I use to do to my classmate in my MCSE class send the shutdown command with -f which forces their computer to shutdown, amids that windows updates will force install and restart, and some viruses will restart your computer in a loop
Hi Natty,
If you did that it would also log that you were the person requesting the shutdown. If the shutdown was caused by "system" then it will most likely be the operating system as john or merete has described.

True, so it could be the results of power failure, are you using vmwares by any chance.
can also be a power spike, or a bad PWR supply
you can swap the PS for a test, and verify the AC

Thanks everyone for the helpful comments. I did find that it was an important OS update that initiated the shutdown/restart. There seems to be nothing wrong at the moment.
Sounds right as I mentioned in my comment above probably critical Updates

Good to hear :)
also - if the pc is in an industrial environment, that can be the cause also :
magnetic, or static spikes, poor grounding, poor AC stability

Could be a critical windows updates.
These force an install and shutdown.
and assist anyone else.

I mentioned updates in the first post here. But I have not seen updates give a Kernel-power message.

Thanks everyone for all the helpful input. I looked further into the system logs and found that it was OS updates that initiated the shutdown and immediate startup right after.

Thanks alot, this was apparently exactly what caused the shutdown & startup.
That's great to hear.
Glad to help thank you
