Abstract: A socket cover includes a body and a base. The base includes a passage with a middle portion and two terminals. The width of the middle portion of the passage is smaller than the width of the two terminals of the passage. The body includes a pin, extruded in a direction parallel with an axis and pivotable about the axis relatively to the base. The pin of the body passes through and slides in the passage. When the pin is abutted against one of the terminals of the passage, the pin lodges in the terminal of the passage, so as to fix the body on the base.

Abstract: A notebook computer including a bottom case and a top panel is provided, wherein the top panel includes a first supporting element, a top panel body and a second supporting element. The first supporting element has a first side and a second side, wherein the first side pivots to the bottom case, and the top panel body pivots to the first side of the first supporting element. The top panel body has multiple sets of first fixing structure. The second supporting element has a third side and a fourth side, wherein the third side pivots to the second side of the first supporting element. The fourth side has a set of second fixing structures, which is inserted into one set of the first fixing structures.

Abstract: An earphone set includes an earphone and a hanger. The earphone includes a shell and a shaft extending from the shaft. The hanger includes a bushing, a connector and a hook. The bushing is mounted on the shaft. The connector includes an annular portion mounted on the bushing. The bushing cannot be rotated in the annular portion just because of a torque derived from the weight of the earphone. However, when additionally subjected to a proper torque, the bushing can be rotated in the annular portion. The hook is rotationally connected to the connector.

Abstract: Methods and systems for updating a source image file in a BIOS memory are provided. In one embodiment of the method, an initialization document is loaded to generate a first image file, and the initialization document comprises a function setting and first and second address information associated with the function setting, and the function setting represents whether a system locked pre-installation (SLP) 2.0 is supported. The initialization document is loaded to write an SLP mark and an OEM public key to the first image file according to the first and second address information, serving as a second image file. The second image file is written into the source image file in the BIOS memory.

Abstract: An automatic network connection device includes a first connection port, a second connection port, a first network connection unit, a second network connection unit, a control unit, and a switching unit. When the first network connection unit operates normally, the switching unit electrically connects the first network connection unit to the first connection port, such that the first network connection unit transmits and receives a network signal. When the first network connection unit fails, the switching unit switches the first connection port to be electrically connected to the second network connection unit, such that the second network connection unit transmits and receives the network signal.
