    Abstract: An electronic apparatus includes a bottom cover, a main board provided with a stud, a screw, a washer, and a sponge. The screw has a head portion having a diameter larger than that of an attachment hole, a male screw portion configured to be screwed into a first female screw portion, and a columnar portion having a diameter smaller than a root diameter of the male screw portion. The washer has a flange portion having a diameter larger than that of the attachment hole, a cylindrical portion having a diameter smaller than that of the attachment hole, and a second female screw portion which the male screw portion is screwable into and passable through. The head portion abuts on the bottom cover to fix the bottom cover by the male screw portion. The flange portion is between the stud and the bottom cover.

    Abstract: An electronic apparatus includes: a chassis; a heat generation element provided in the chassis; a heat transfer member in contact with the heat generation element in a heat-transferable manner; and one or a plurality of heat dissipation mechanisms configured to cool the heat transfer member. The heat dissipation mechanism includes a first cooling device configured to cool a first main surface of the heat transfer member, and a second cooling device configured to cool a second main surface of the heat transfer member opposite to the first main surface. The first cooling device includes a first heat dissipation plate in contact with the first main surface in a heat-transferable manner, and a first blower mechanism configured to blow a gas to come into contact with the first heat dissipation plate.

    CPC classification number: H05K7/2039

    Abstract: A heat radiation structure includes a mesh that abuts on a surface of a die, and a vapor chamber that interposes the mesh between the surface of the die and the vapor chamber. The mesh includes a heat generation element abutting range portion that is provided at a central portion of the mesh, is impregnated with a liquid metal, and abuts on the surface of the die to receive heat, and a pair of heat generation element non-abutting range portions that continuously extends from both sides of the heat generation element abutting range portion and does not abut on the surface of the die. Each of the pair of heat generation element non-abutting range portions is fixed to the vapor chamber via a sheet material. Each of a pair of the heat generation element non-abutting range portions is interposed between a pair of the sheet materials.

    Abstract: An information processing apparatus includes: a controller that outputs notification information based on input information; and a processor that executes system processing based on an operating system (OS) and operation of thermal control processing by control of a Basic Input Output System (BIOS) using the notification information output from the controller. The controller accepts an operation signal indicative of an operated key according to a user's operation on a keyboard; determines whether the operated key is of a specific combination of keys based on the accepted operation signal; upon making a determination that the operated key is of the specific combination of keys, outputs, to the processor, a result of the determination as the notification information; and without another key being pressed after the result of the determination is output from the controller, the processor executes the thermal control processing based on the result of the determination.
