Hi,
on my old workhorse, Asus Sabertooth 990 FX Rel 1 with bios 1604 and 8150FX CPU, I have
occassionally failures on suspending via GUI, My desktop is KDE, F29 and I use
'Application Dashboard -> Suspend' in which case systemd tries to suspend the
box. But sometimes box doesn't sleep at all, instead:
- it either seemingly goes to S3 (i.e. every peripheral powers of and power LED flashes to
indicate S3 state) but power supply does not cut off
- in another case, it goes to S3 but very rapidly powers back on (so that I can hear
PSU's in-rush current limiting relay to loose and close in between about a second)
Now comes the big BUT: If I run following commands from terminal as a root:
sync && echo mem > /sys/power/state
I have not experienced ANY problems at all. For those who had, maybe test this command
compound is worth trying?
