On your own laptop you can do what you like - change the settings to sleep the laptop hibernate the laptop, shut down the laptop, do nothing... I dare say some third party software may let you do something else.

I am intrigued as to what else a laptop can do when the lid is closed.
Sleep 
Hibernate 
Shutdown
Nothing 
Screensaver 

What "something else" can there be?

There is hybrid sleep, where the computer dumps its RAM to disc like it would before hibernating but then keeps systems in lower power mode rather than turning off. 

That's for desktops without battery backup - so they don't loose data in a power cut. It's pointless  and counter-productive on a laptop.

That would be the main use case, though certainly with some OS its possible to enable it on other devices even if its of questionable use.
