Abstract: According to a notebook-sized personal computer of an embodiment, a base housing retains an arithmetic unit, an antenna having antenna elements, and covers. An LCD housing retains an LCD. Hinges rotatably couple the base housing and the LCD housing to each other. In the base housing, a pair of depression sections are formed by depressing both ends of one side thereof. In each of the pair of depression sections, an antenna element is accommodated. On the base housing, to end sections respectively adjacent to the pair of depression sections along the one side of the base housing, the hinges are respectively provided. The covers respectively accommodate each of the antenna elements, and are constituted of a material through which a radio wave is passed.

Abstract: According to one embodiment, an electronic apparatus includes a case, pen, and antenna. The case includes an input surface and a peripheral edge having an engagement aperture opened in a direction along the input surface. The pen is used for an input operation with respect to the input surface. The pen includes an insertion piece which is made of synthetic resin and is attachably and detachably engaged in the engagement aperture while the pen is arranged against to the peripheral edge. The antenna is disposed inside the peripheral edge to be adjacent to the insertion piece in a distance which is less than the size of the insertion piece in a transverse direction of the input surface.

Abstract: According to one embodiment, an electronic apparatus includes a housing, a first radiating portion in the housing, a second radiating portion in the housing, a first heat pipe thermally connected to the first radiating portion, a second heat pipe including a portion crossing the first heat pipe, the second heat pipe thermally connected to the second radiating portion, and a fan configured to blow air to at least one of the first radiating portion and the second radiating portion.

Abstract: According to one embodiment, an EC/KBC reads data of an acceleration sensor. The EC/KBC determines whether a computer is in a top heat state. If the EC/KBC determines that the computer is in the top heat state, it notifies a BIOS stored in a BIOS-ROM of a message to this effect. The BIOS which is notified from the EC/KBC that the computer is in the top heat state notifies an OS (Operating System) of the message to this effect. The OS sets a CPU to a power saving mode by an existing means such as the power saving utility of the OS, and sets the computer to the power saving mode.
