My computer was in the middle of running a long computation in Matlab when it went into hibernation mode. Clearly I am not understanding the definition of "how long your computer is inactive", see screenshot:
Can someone please explain what the times in the drop down boxes for the sleep/hibernate settings mean in terms of activity.
Putting it simply - the only two activities that reliably prevent sleep/hibernate are keyboard and mouse/touch input.
In all other cases, applications must explicitly and (in my experience) periodically tell Windows "I still need you!" if they require the computer to stay awake. Media player applications are a good example.
If Matlab has no option to "keep your PC awake", you'll have to disable sleep/hibernate while you perform long-running calculations.
