Description a4524556 2014-11-24 14:29:15 UTC

My laptop doesn't resume from suspend to ram: when I wake up it, I see only a black screen so I must do a hard reset.

I've make same try:

1) dmesg > dmesg_before; echo mem > /sys/power/state; dmesg > dmesg_after
dmesg_after not exsist

2)echo core/processors/devices > /sys/power/pm_test and dmesg > dmesg_before; echo mem > /sys/power/state; dmesg > dmesg_after

dmesg_after exist

Has suspend-to-RAM ever worked on this laptop with any version of Linux?

Does hibernate to disk work?

please refer to https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/power/basic-pm-debugging.txt and check what pm_test modes work for you.
