Anti - Surge warning pc rebooted on its own when i wasnt in home.

[sew333]

I was trying to figure out if my power was out last night during the small power outage so I can figure out whether to throw away perishable foods. I think my computer was on when I came home this morning (although I was tired so I certainly could have turned it on without thinking). I don't have the "startup automatically after a power failure" checked in energy saver nor do I have a UPS. If I type "last" in terminal, it has a reboot at 4:37am this morning (I was not here at that time). Also, the system log says

4:37:43 AM locationd: locationd was started after an unclean shutdown

So that seems to indicated that computer shut down and restarted on its own with + yes, ANTI SURGE WARNING. "“Power supply surges detected during the previous power on ASUS anti-surge was triggered to protect system from unstable supply unit."

I did a test. I unplugged my pc for about a minute. It didn't start up on its own.

Could it be that there was a very brief power disruption/flicker that caused it to reboot with Anti Surge on its own?
