The lid switch is exposed as input device in Linux. logind opens that device and reacts on it. However it gives DEs the chance to inhibit this if they desire so. Gnome at least doesn't inhibit it perminantly though, but some components might delay suspends, for example Telepathy to log you out of your Jabber server... Normally when you close the lid logind should log something about "Lid closed" or so... Look around the logs around this to figure out what mightbe going on.
