That was my reaction, to the question, too.
I’m not sure what power down options my current (Linux) OS has. I just let the battery die sometimes like a normal person.
Edit: The battery management defaults are so good, I have to forget about it on a shelf for several days before it - well I don’t know what it does, because I’m ingoring it. Maybe it powers down, maybe it suspends, maybe it does some kind of emergency shut down…
If I’m putting it into a bag, I’ll power it off. It (Debian Laptop) boots faster than my Android tablet anyway, and I worry about it overheating without airflow.
The rest of the time, I just lock it and leave it to make it’s own power decisions. Whatever the defaults were, from install, they seem fine.
It boots so fast, I don’t notice if it was suspended or a cold boot unless I happen to have an attentive moment to watch the boot sequence carefully.
