> I turn the lid down on my laptop and it goes to sleep. It pull it up and the system comes back up. Reliably. Every single time.

It's not the case for my M1 MBP. Having it connected to an external USB C/Thunderbolt monitor makes it simply refuse to sleep, even when clicking on the Sleep button, closing the lid, etc. Even outside of that it's a crapshoot if simply closing the lid when on battery power will actually make it sleep, or i will realise on Monday it never slept.
