Abstract: A switch structure comprises a gripper, a splinted trough and a cutoff circuit. When the computer puts in the case of the server apparatus, the gripper can directly stick on the corresponding splinted trough to make the computer stick in case and trigger the cutoff circuit to generate a pulse signal to the computer for booting the computer. While unlocking, the cutoff circuit generates the other pulse signal to the computer to make a graceful computer shutdown.

Abstract: This invention discloses an expanding card fixing structure for fixing an expanding card in a computer. Such structure comprises an expanding slot, a fixing base and a buckle batten. The fixing base is set in the back of the computer and the expanding slot. Besides, there are at least a slot and a buckle in the fixing base. There is a buckle slot in the buckle batten connecting the buckle in the fixing base. Moreover, the buckle batten vertically extends at least an arm corresponding to the slot. And there can be an extended batten corresponding to the slot at the back of the expanding card. While inserting the expanding card into the expanding slot, the extended batten is simultaneously inserted into the slot. Then the extended batten clips firmly between the arm and a side of the slot through inserting the arm into the slot.

Abstract: This invention discloses an expanding card fixing structure that applies to fixing an expanding card in a computer. Such structure comprises an expanding slot, a conversion apparatus, a base, a -type or L-type batten and an upper cover. After inserting the expanding card into the slot side of the conversion apparatus and inserting the card side of the conversion apparatus into a expanding slot in the motherboard of the computer, the front end of the expanding card is pressed down through rotating the arms of the batten which is pivoted on the base, and then the batten continuously is pressed down by the upper cover.

Abstract: A portable computer comprises a machine body approximately rectangular in shape comprising a front end, a rear end, a top face and a bottom face; a liquid crystal display approximately rectangular in shape comprising an upper end and a lower end; and a connecting device comprising a front end and a rear end. The front end of the connecting device is fixed to the rear end of the machine body in a rotatable manner, and the rear end of the connecting device is fixed to the lower end of the liquid crystal display. The connecting device enables the liquid crystal display to be folded upon the top face of the machine body by a forward rotation or upon the bottom face of the machine body by a backward rotation.
