That behavior works as designed.  When you unplugged the PC or turned off the electrical outlet, the computer detected it as a power outage.  When you reintroduced the power to the PC again, it will be on for a few seconds to check the AC behavior settings in BIOS:

If the setting for system response when power is restored =  Power OFF, the PC will stay off.

Otherwise, if the selected setting =  Power ON, the PC will be turning back on.

When you keep the PC plugs into a live outlet, the behavior will not occur again unless it's an actual power outage. 

I hope that my response provides the answer to your concern.
