Generally, I want to have energy saving active. Normally my PC doesn't have to run at full power while I'm away for lunch.
BUT sometimes I have programs running that perform some operations while I'm away, like rendering a 3D scene. Obviously Windows seems to think that it's inactive even though the processors are working, and after a few minutes it goes to sleep and doesn't finish the job it should work on.
Of course I could just change my energy saving options, but it's a nuisance having to fumble around the menus every day.
Is there a way to tell my computer not to go to sleep when a certain program is running?
