When you restart a PC, does it completely “shut down”? If it does, what tells it to power up again? If it doesn’t, why does it behave like it has been shut down?

So I understand how the physical power button works on old PC’s to turn a computer on — it actually made a physical connection to enable power.
But on a MacBook for example, you hold down the power key on the keyboard for a few seconds, which is totally different.
I assume that whenever the laptop is even slightly charged, or always when it’s plugged in, some part of it is always on “a little bit” to detect pressing the power key?
