The present invention discloses a structure for turning on/off the wireless communications of a notebook computer by a latch member, which comprises a latch groove disposed at a free end of a screen display of the notebook computer and a latch member disposed on a main system of the notebook computer at a position corresponding to the latch groove, wherein the latch member comprises a push member protruded from the front end of the main system, a hook section extended from the top of the main system and a guide pole disposed at an end corresponding to the other end of the push member. Further, a resuming type switch is disposed at a position corresponding to an end of the guide pole, such that when the screen display is lifted up and opened to press the push member of the latch member, the guided pole of the latch member presses the switch and thus the switch is electrically connected to turn the wireless communication online.
