no if the equipment plugged in at the wall is turned on and the leads are all working the switch will have a green light, It maybe that you have a faulty wall socket. Is it part of a double socket? Maybe they ran out of single socket plates and used a double but only wired one side. Remember that each datapoint had to be accompanied with a double electrical socket, so if you have a double datapoint there should be 4 power sockets beside it.
