How does it* know to turn itself back on?

Your system has a lot of different power states. They are managed by ACPI (Advanced Configuration and Power Interface) sitting on the motherboard.
Now when the operating system wants to reboot, it sends a command to that ACPI thingy to do so. The system goes down and ACPI turns it back on.
Stuff like power buttons on keyboards trigger similar ACPI stuff to work.
