Had this probelm after the automatic W10 upgrade.
I had it working perfectly and hibernating too.
When I close the computer either shut down or sleep and go to restart the acer screen comes up without the spinning wheel.
It just hangs
I have to hold the off button till it crashes and then restarts normally.
I have tried hibernate -h off and on
I have tried all sorts of settings in the power configuration settings
Hibernate no longer available at all.
