dalchina confused the post by showing a screen shot of the wrong settings.
Yes, it has been removed, but the options are still available. I'm assuming you are trying to follow instructions for fixing an external monitor that randomly goes to sleep? If that's the case, expand Sleep, the System unattended sleep timeout is the 2nd option. And, by the way, I had to set mine to 999. 20 minutes worked for a few weeks, but then it started going to sleep again. It hasn't gone to sleep since I increased it to 999, but I only changed it a week ago, so I'm still considering it in testing.
If that's not why you needed that setting, please, disregard the previous paragraph.
greenangel,
By the way, dalchina posted the right diagram. The question was changed afterwards.
You can write in Never instead of entering a number for that sleep setting.

Thanks Try3.. - pictures sometimes make for clarity but it somehow didn't work out that way in this case.
