Thanks for posting that. Can you try the following, and post back the output?
In an elevated command prompt, please do this:
powercfg -h OFF ,and hit enter and then
powercfg -h ON, and hit enter.
This will turn off the hibernate function, and then turn it back on again. I'm hoping this "reset" will solve the problem. If not, we can call in the "big guns" on this.
