I couldn't make s2ram work on my machine and /sys/pci/.../power/state virtual files were removed one year ago. How can I test suspend/resume ?

See Documentation/power/states.txt

$ cat /sys/power/state

^^^^ nothing.

Cat does nothing because it doesn't change the current state. It should return:

standby mem disk

if the kernel is built to handle power management. If it does return any of these values, to change state you would type (as root): echo mem >/sys/power/state # suspend to ram # or echo disk >/sys/power/state # suspend to disk (hibernate).
