Chevy cobalt power steering problem? - power steering cobalt

Sun 07 Chevy Cobalt is my only lost power steering OK. It was just a day at random, but when I the car off and then back to power steering and only takes a few minutes before departure. When this happens, I think need a little liquid, so I went to him to fill, but could not find where is the power steering fluid. I looked online and discovered that it uses the liquid, but with an output of system and the system could be triggered? Nobody knows whether this is true or what is the problem?
