Greetings,
The Pinebook Linux Power-Down Procedure that has been found to be most effective (although not 100% reliable) is to use the "power button" to pull up the shutdown dialogue !
Testing has shown that if the shutdown command happens in a terminal (or serial console), or if it is selected with the mouse from the System menu or the tool-bar the system correctly hits the systemd target shutdown; however, the hardware ARISC PMIC does not power off the system.
On the other hand, if the user will press the actual "power button" (upper right hand key on the keyboard) then after the systemd target shutdown the hardware will correctly (most of the time) power off the hardware.
... but don't trust it, check it !!

Good to know! Indeed I've experienced that sometimes a reboot or shutdown doesn't seem to complete properly, will hit the power button only for now to see if indeed proper shutdown is done!

Greetings,
In this segment I have captured the OS shutdown to : target shutdown ( look for it in the log below ); beginning with the OS unmounting of the Local File Systems (the critical piece of shutdown )!
After this line:
[ OK ] Reached target Shutdown.
... we see the power down console messages ( usually never seen by human eyes ) and a long string of messages beginning with this line:
[48025.784817] Power down. ( look for "hello boot0 starting" )
... and culminating in this line ultimately if the hardware actually powers OFF :
[ 8.036]power off set power off vol to default
Lowly humans get to see a brief battery charging icon on the screen at this point ( boot0 arisc uboot ).
Its amazing what we can learn about the system ( hardware and software ) by studying the serial console logs !

Greetings Pinebook fans !
... the plot thickens. Powering down with the "power-button" and then clicking the "shutdown" button is the best; but the Pinebook can be successfully powered off from the terminal too !
sudo poweroff <==== use this one
vs
sudo halt
More likely than not sudo halt will leave the Pinebook in a powered up state; from a hardware perspective. On the other hand, sudo poweroff will more likely than not result in the hardware actually powering off the system.
