Getting rid of the 30s period before sleep

[Tyrannocaster]

Hi, everybody - new user here. I can't figure out how to get rid of the 30 second countdown that I get when I want to suspend the system. I'm talking about the one I get down in the right end of the menu; the one that comes up when I go through the whisker menu doesn't do this, but it's more clicks. I know I can just click the mouse and bypass it, but I'd like to just click on SUSPEND and have it suspend without any backtalk.  ;D How do I do this?

Thanks!
