Does the red light on at the bottom of the mouse light when it is moved and does pressing Num Lock on the keyboard cause the Num Lock light to go on?
If they do not light up the keyboard may be unplugged. It there is a USB keyboard extension check that there is a protective knot at the joint. Even if it looks to be properly plugged into the central computer, un-plugging, waiting several seconds, and plugging in again may solve the problem. If the station is still down but the mouse and keyboard are alive pressing Ctrl+Alt+Delete should solve the problem. If these do not solve the problem Reboot or schedule a reboot for the 1-Box. If this fails report the problem with details to Userful. Do the same thing if a particular station gives repeated problems like this.
