Any way to make my Macbook not sleep when closed?

[chaoticbear]

I read in the manual that I can make it not sleep if I plug an external monitor/keyboard/mouse into the computer, but what I need is a way to make it stay awake and transcode video throughout the night/when I'm in class. Is there any way to do this? I've been just leaving it open a couple of inches, but I'm afraid of causing long-term wear to the hinges, and I don't actually even have it on a desk, so I can't leave it open (it might get knocked over or god knows what with a dog running around)

You could also just turn down the brightness of ur screen to 0 ...

another way is to reset the Macbook and immediately shut the lid.

Works rather well, but i never liked the idea of running my laptop with the screen closed.
