When you restart a computer, after it shuts down, how does it know to start up again?

When you restart, power to the Motherboard isn't actually cut off, so the bios just automatically boots the operating system.

I suppose the equivalent is getting in bed, closing your eyes, then getting out of bed again. You haven't actually fallen asleep, but it seems like you have.
