My Macbook air is showing a black screen except for beachball mouse after partitioning

i partitioned my mac to "mac OS extended Journaled" about an hour and a half ago. almost straight after i started it froze but the mouse still moves. then i accidentally shut the lid. it now has a black screen and the "spinning beach ball".

i cannot find the serial no.


Edit: i have just found the box for the mac and am going to open a chat

OK, you'll need to Power it down...


On a Mac without an eject key (like the MacBook Air or MacBook Pro Retina Display), you can force your computer to shut down at any point by pushing Command + Control + Option + Power button. Before you resort to this, first try a force quit on a problem application by pushing Command + Option + Esc.
