Abstract: An electronic apparatus having a cooling device that can reduce size and cost thereof while maintaining sufficient cooling performance of cooling a portable information apparatus is disclosed. The electronic apparatus includes a portable information apparatus and a cooling device. The portable information apparatus includes a heat-dissipation heat sink thermally connected to a heating body. The cooling device includes a cooling unit for absorbing heat from the heating body. The cooling unit includes a heat-receiving heat sink that is thermally connected to a heat-dissipation heat sink when the portable information apparatus is connected to the cooling device, and a radiator that dissipates heat absorbed in the heat-receiving heat sink to outside. The radiator is disposed on an exhaust path from an air outlet of the portable information apparatus while the portable information apparatus is connected to the cooling device.

Abstract: An electronic apparatus capable of achieving sufficient heat transfer efficiency between a portable information device and a cooling device while preventing a heating member from being exposed at an outer surface of the portable information device is disclosed. The portable information device includes a heating body and a cooling device. The cooling device is detachably connected to the portable information device, and is configured to absorb heat from the heating body. The portable information device includes a heat-dissipation heat sink thermally connected to the heating body, and multiple apparatus shutter members covering the heat-dissipation heat sink so that the heat-dissipation heat sink can be freely covered and uncovered. The cooling device includes a shutter driving mechanism that opens the apparatus shutter members when the portable information device is connected to the cooling device, and a heat-receiving heat sink thermally connected to the heat-dissipation heat sink.

Abstract: A portable computing device prevents a magnetic disk unit protecting function from impairing usability for a user when the processor is used as a tablet PC. The portable computing device includes a magnetic disk unit, a magnetic disk unit protecting section operable when predicting an occurrence of an impact to carry out a magnetic disk unit protecting function for retracting a head of the magnetic disk unit, and a detecting section that detects whether a user is holding the portable computing device or not, and responsive to detecting that the user is holding the portable computing device, temporarily deactivating the magnetic disk unit protecting function.
