SuspendMode=mem in my sleep.conf
Works fine, usually about 5%/day
No red led, only green (not talking about barrel plug,power plug)
I only enter/leave suspend with short power button press,,
all other keys and touchpad are dead when sleeping
It is unclear to me, at this point, interaction with uboot
(stock on emmc, manjaro on SD)
--edit, much later--
Just retested debian10 with updated kernel, no change re sleep
(effectively no power savings)
