Where is the volume control button on the Dell Inspiron 15?

I just got the Dell Inspiron 15, and although I can control the volume from the button on the desktop, I want to be able to control it - it's usually right near the place for the headphones, but I can't find it. Is it possible that a computer doesn't have this button???Where is the volume control button on the Dell Inspiron 15?
I have a Dell Inspiron 1501, and for me the volume control is a combination of buttons. In order to lower the volume, I have to hold the FN (Function) button (located at the bottom left hand corner of the keyboard) and then select volume up or down by clicking Page up or Page down.Where is the volume control button on the Dell Inspiron 15?
Bottom right corner, to the left of the time. This is of course if you're using Windows, it applies to most Windows OS's. There ya go.
