When hitting the keyboard the computer reboots instead of resuming. Is there anything wrong with the hibernation?
When resuming from hibernation computer does normal boot, then checks for resume image and loads it. Please post full “journalctl -b” output after resuming from hibernation (upload to http://susepaste.org/ if it is long).
Resume from hibernation now works when the computer remains connected to the power outlet. It still boots when disconnected and reconnected. journalctl -b: SUSE Paste
There is no attempt to resume indeed. Could you add “systemd.log_level=debug” and remove “splash=silent quiet” from kernel command line, try to resume once more and post output again?
Many thanks for having a close look at the problem. When making the changes proposed I noticed the current boot had still old and faulty parameters. Rebooted and tried again: Hibernate, unplug AC power, plug in again, hit the power button and got the following resume from hibernate:

Not sure I understand the current state. Does it now work? If yes, what was the reason and what did you change?
Yes it does!
What was the reason and what did you change?
The answer is a bit lengthy. Actually I did never consider hibernation. Sleep works fine. Boots only take place on my openSUSE systems upon returning from vacation, kernel updates or power cuts.
This changed a month ago, when I upgraded the laptop of a friend from Windows 7 to openSUSE 13.2. The installer expert partitioning menu offered an option for adjusting swap to extend to the size necessary for hibernation. I clicked yes and sleep as well as hibernation worked upon completing the installation.
The situation on one of the desktop machines was more complicated. I had installed openSUSE Leap 42.1 in March and selected swap half the size of physical RAM. When I wanted to enable hibernation I deleted one partition, increased swap size to physical RAM and installed Grub 2. I assumed this would change the kernel parameters accordingly. However the Grub 2 installer kept the old line and hibernation failed. Eventually I detected the erroneous parameters, fixed them and reinstalled Grub 2. Still hibernation failed and the machine rebooted. I thought the new parameters were used but journalctl showed the old parameters.
Finally I had an explicit shutdown, power cut and and boot from scratch. This fixed everything. Sleep and hibernation now work as flawless as with the laptop installed from scratch as described above. Again many thanks for the rapid response an detailed look into the log file.
