I think it’s mostly true for modern usage. Powering off a laptop doesn’t fully disconnect power, because the power button is not a true switch but just signals to some power management hardware which is ALWAYS on as long as there is battery charge or plug power — it catches the signal from the “power” button and executes a true power switches to start the computer boot cycle.
