MBP goes to sleep when watching Youtube videos

[techmonkey]

Whenver I watch a video online, my MBP goes to sleep. Is there a settings that will stop this from happening when video is playing? Seems like a no brainer. When I watch videos with Quicktime or VLC, this doesnt happen.

I found a program called "Jiggler" that moves your mouse automatically every X minutes, but Id rather not install a program to do something this simple.

That's because with Quicktime, VLC or DVD Player, OS X knows not to put it to sleep based on the program. With Youtube, this is just an internet browser so why wouldn't it go to sleep?

You can go to Energy Saver and tell the computer not to sleep though.

Basically the video is playing inside your browser. So the OS does not see this as activity. As far as the OS is concerned the computer is inactive. The software you mentioned which would move the cursor every X minutes or so is a good option. Otherwise I guess you will have to modify the power settings to get around it.
