#186027 — leaving the hibernate state

hi,
I installed pm-hibernate on my laptop, and it seemed to work,
i.e. I got a black screen 10 to 15 seconds after issuing the 
pm-hibernate command, but I was unable to wake-up the laptop.
Looking on Internet I found tons of documentation about suspend and
hibernate, but amazingly, not a single line about the way to leave these 
states. 
Of course, I tried almost all the keyboard keys, without success, and 
all I could do was to  hold down the power button, which gave the normal
startup, with a "recovering journal".
My laptop is a Lenovo ideapad 110, running Stretch
Should I configure something to use pm-hibernate?
I have in syslog lines like:

     Hibernation image not present or could not be loaded.

but I didn't find how to  fix that.(adding resume=/dev/disk/by-uuid/...
in /etc/default/grub changed nothing)

best regards,

Have you tried any of these tests?

    I tried the first one: it crashed my laptop, and after reboot, I got "recovering journal"
    I thing that the problem acrually comes from a too small swap partition. I'll increase it, and post the result.

    I increased the swap partition to twice the ram size, but hibernate still doesn't work
    (cf my next post: "hibernate uses a wrong UUID"

So you've ruled out swap size, UUID mismatch and have actualy been able to
hibernate, though you're still unable to resume, is that correct?

The doc above has hints on test_resume, you may try it.

    Not really, as the image is not written after hibernate. As I already said, I abandonned the idea of doing hibernate,
    and use resume at lid close. The battery then lasts more than 24 hours,  which is largely sufficient.
