Dear
I am make nano to sleep,but when it wake up,sometime nano power down.
as follow:

Hi,
Could you share the full step of how you entering the suspend and wake it up?
root@asa-desktop:/home# echo +30 > /sys/class/rtc/rtc0/wakealarm

Hi,
Please at least give us some description. It does not help if you just copy and paste the same log again and again.
I want to make nano sleep 30 seconds and wake up automatically, as follow:
echo +30 > /sys/class/rtc/rtc0/wakealarm
echo mem > /sys/power/state
But sometimes nano power down after it wake up.
If you don’t set the wakealarm, and just wake it up manually, will you hit this error?
How to wake it up manually?
NO ,Press the power button can’t wake up it
please use below command instead of the echo mem command.
sudo systemctl suspend
