@Dr Herbie: Why not change it to power off then? Or do you use both? Granted, I'd love it if computers came with a button for sleep and a separate one for power.
I really wish Microsoft would make stuff like this more accessible to the common user. They were making progress with the notification tray and control panel (categorization, searchability, etc.) but then along came W8... Maybe they can get it right in PC Settings in the Window 8 Store App environment but leaving stuff split between the two "control panels" really makes the beautiful Surface not so beautiful.
