Help: Pinebook Pro will not enter sleep [Manjaro 20.04]

>What is the SleepMode=mem trick and did it work for you?
in /etc/systemd/sleep.conf
Suspend 3 (sometimes called s3 or s2ram), so far, is the ONLY worthwhile sleep
All others are barely better than screen blanking
Usually ALSO need a bsp uboot, for that version of trust
manjaro was 1st to have a kernel that "worked",,tsy kernel
Elementary uses this kernel, updated uboot no good, have to change (to get s3)
Fedora 32  also works, haven't updated recently so???
xmix's kernel supposedly also works
NO OTHERS (that I know of) can do s3
FWIW,,,,,, if you have more info,, post,,, look for "suspend 3" in dmesg
(and NOT s2idle)
--edit--
BTW if you have nvme, don't bother, pcie driver won't suspend
Really smart to back up 1st 16m BEFORE an upgrade, just in case a new uboot is "not so good", sometimes gets installed 'behind your back'

I'm running Manjaro, if I understand you correctly it should be able to go into S3?

Here are the contents of /etc/systemd/sleep.conf, what do I need to change? I saw someone mention commenting out the SuspendState=freeze line...

[Sleep]

#AllowHibernation=yes
#AllowSuspendThenHibernate=yes
