If you find a better configuration please share.

At the time of implementation hardware sleep of any kind was unreliable so this mode we're using is just kernel-based sleep.
Thanks for the quick reply! Note that in `/etc/systemd/sleep.conf` I had this at the end:
Code:
SuspandState=freeze
I corrected the typo (Susp*a*nd), and will test a bit more. The man page doesn't give me a lot of detail on the power saving differences between the different options, but it seems that `mem` means it will look at /sys/power/mem_sleep so I'll have to dig around and do some more testing of the various options.
Note that I FULLY support reliability :-) so can understand it may not be reasonably possible to find a better powersaving in sleep, since there are complaints about it disabling sound, possibly wifi, not waking at all, etc. Armbian really is great for the PBP, btw. I am currently on 5.10.21, and use Cinnamon (4.8 via PPA that we maintain) which is really quite performant (older Cinnamon up through 4.6 was sluggish).
