Powering off & won't power back on w/o battery disconnect

[jimsurvak]

The next time this happens, try instead to do a hard reset,,
press and HOLD pwr button 20+ seconds, then a normal start press
Actually, first try a hard power-off, hold pwr button ~8 seconds
This is probably a failure to wake from sleep, not sure where settings are in cinnamon,
and not sure just what notices wake signal. I wish I knew
If this works (and I would bet it will),, change uboots,, maybe uboot-pinebookpro-bsp
Do realize that  the install actually doesn't, you still have to do the dd
Also, sometimes the install changes extlinux.conf,, the root=value,,,wrongly
So 1st of all , make a backup of it (before installing bsp uboot)

Unfortunately that doesn't seem to have worked. As far as the "hard reset" goes, that is.
I didn't actually dd the image, I used Etcher because every time I try dd I somehow managed to mess it up & it doesn't boot.

I do have the original factory Debian-based image (from before they moved to Manjaro) on a microSD card. When using that the system will boot to the "Open Sesame" screen & simply reboots. Not sure how to troubleshoot from here.
