Explanation of LED behaviour on different models of Pi about documentation HOT 2 OPEN

1. Do all Pi-5s have a power button? I don't think mine does. It's a Canakit Pi-5 with the aluminum case. Am I missing something?
2. What is the "shutdown state" and why does it occur? Besides pressing the power button (if there is one) is there another way to get it out of that state? In my case I left it on, idle for a couple of hours, and found it in this state.

from documentation.

@stevecoh1 Questions like that should be asked on the forums, not on Github.
But yes, every Pi 5 has a power-button (see https://www.raspberrypi.com/products/raspberry-pi-5/ ), but perhaps not all Pi 5 cases make it externally-accessible? 🤷
