Another possibility -- corrupted kernel upon install/upgrade.
It may sound stupid, but I just experienced a similar case with the
Power Management features when I did the network upgrade from F19 x64
KDE to F20 x64 KDE on my Dell D531. The kernel version embedded is
3.11.8-301. But, for some reason, it seems like part of it is corrupted
or damaged somehow because hibernation doesn't work correctly. Whether
it's from the menu, *sudo pm-hibernate*, or *sudo systemctl hibernate*,
it would go down properly; however, when you power it on, the session's
lost and it acts like it was a restart or fresh boot. [There was also a
problem with several RPMs installed in it to where I couldn't install
new programs because most of them were newer than what was available in
the repositories.] So, out of aggravation, I did a total reformat and
clean install from the F20 KDE LiveCD, only to have the same problems
I came across a random article in http://ask.fedoraproject.org
Yahoo! search and came across the suggestion of reinstalling the kernel.
As long as you're not trying to reinstall the current one, you can do a
fresh kernel install. I did a search on the Fedora buildsystem
site for another available version
of the kernel. I recently upgraded to 3.15.9-201.fc20.x86_64
downloading both the kernel and the headers. Then, I just did a *sudo
yum localinstall kernel kernel-headers* from the terminal, not from
Apper (or whichever Software Management GUI you're using). Just in case,
I rebooted into the new kernel I installed and tried the suspend and
hibernate options. Everything worked fine. I haven't tried the current
delta kernel -- 3.17.8 -- that's in the repository, but, if you do, I'd
suggest doing it from the terminal with the full install as a precaution.
Hope this helps,

Maybe as a short term fix you could go to the power management
settings and set the 'event' for closing the lid to 'lock screen'
instead of 'sleep'
