Power Outage or hardware?

@xxx123

When the PC has power loss it shuts OFF to protect the PC.
It's supposed to do that.

The BIOS setting you are referring to, doesn't do what you think it does.

Yeah i know. But if i switch fast button in power cord <off/ON> then pc shutting down and then rebooting itself up.

Yes. Because the motherboard doesn't SEE that as power loss.
It interprets that as if you pushed the Restart button.

The PC is NOT supposed to automatically restart after power loss.

So for what is that option RESTORE ON AC POWER - ON. ?


Also for pc there is difference between real power loss and pulling off/on power cable or flipping the switch on power cord ?

That's for when you TURN the power back on... not for when it comes back on by itself.

You DON'T want the PC to come on by itself after a power failure... that can damage the PC.

Ghot, actually this is what PC supposed to do. In case of power outage.. this option enables the PC to automatically power on when power is reestablished..

I guess, you were right on the short power OFF/ON interruption.

That option:Turn on after AC Power Loss

So how this is working? I was thinking that pc should boot itself up when power is restored after brownout/outage.

Correct.

But I wouldn't play too much with it. It is not something that any equipment is built for... One of your system components will fail, sooner or later
