A bar is placed on the circle (right).

 

If a wire is connected to the socket, standby power will be generated even if the power is turned off.

Generally, standby power is used for air conditioners and set-top boxes.

 

I also found that the laptop is using standby power.

It's enough power to run the refrigerator for two months, just so you know.
