So I had a funny (and frustrating) encounter today. Set up my first overnight render on my work computer last night and came in this morning to see it had gone to sleep and paused my render just 15 minutes after I started it (and my "go to sleep" settings are set to 15 min), but this should not happen because the computer is not inactive.

I thought to myself, this has never happened to me before, and proceeded to do some searching online. Sure enough, I find this thread from 4 years ago where I complain about the exact same thing. Facepalm. It hasn't happened that I'm aware of in the intermediate 4 years, so I don't know if I fixed something or it was a random occurance.

I did a little test on the current render, letting it go to sleep. This time it took 30 minutes, but the computer went to sleep, pausing the render (but not killing it).
Windows 7 x64.

Anyone else had this happen at some point?

Hibernate is disabled and it still does this, by the way.
