An apparatus for heat suppression in an initial setting mode includes, in one embodiment, an execution unit of an information processing device that executes an operation related to an initial setting mode of the information processing device, a power supply that supplies power to one or more heat generating components of the execution unit, and a controller that controls at least the power supplied by the power supply to make an amount of heat generation of the execution unit in the initial setting mode lower than the amount of heat generation of the execution unit in an operating mode after termination of the initial setting mode until fulfillment of a predetermined condition. A method and a computer program product also perform functions of the apparatus.

Heat suppression in an information processing device in an initial setting mode

Noise generation caused by sudden rising of a rotational speed of a heat radiation fan when a user has no intension is prevented. A temperature management system located on an information processing apparatus is configured by a system including a processor and scheduled tasks, a performance control system which controls processing ability of the processor and a temperature control system which includes a heat radiation fan and controls a heat radiation amount thereof. The processor executes the scheduled tasks when a state where a usage rate is low, such as an idle state, lasts. The temperature control system controls the rotational speed of the heat radiation fan in accordance with temperatures of electronic devices including the processor. The performance control system lowers processing ability of the processor before the rotational speed of the heat radiation fan rises in accordance with a temperature of the processor which executes the scheduled tasks.

Temperature management system, information processing apparatus and controlling method

A method, apparatus and computer program product are disclosed. The method includes detecting ambient light around an electronic device, determining whether a user is present based on the ambient light, and controlling an operation of the electronic device. The apparatus includes a component that consumes electric power, a light sensor that detects ambient light, a frequency analyzing unit that specifies a frequency component, and a control unit that determines whether a user is present and controls an operation of the component. The computer program product includes code to perform detecting ambient light around an electronic device, determining whether a user is present based on the ambient light, and controlling an operation of the electronic device.

Method, apparatus and computer program product for user detection and operation control

A user detection apparatus includes a processor for an information handling device and a memory that stores code executable by the processor. The code is executable by the processor to detect a user in a user space that is proximate to the information handling device in response to an airflow being detected in the user space and, in response to detecting the user, resume or begin operations in the information handling device.

User detection apparatus, systems, and methods

An information processing device suppresses the entering of a state unintended by a user in a standby mode. The information processing device, which has a standby mode and a normal operation mode, has a mode control portion changing the mode to the standby mode of bringing the state into a first low power consumption state and configured to be switched to a first operating state in which background processing is executed in response to a stop of a display of a display portion, and a power setting processing portion configured to set a first upper limit power consumption in the first operating state and a second upper limit power consumption in a second operating state in the normal operation mode, and set the first upper limit power consumption so as to be lower than the second upper limit power consumption when the mode control portion changes the mode to the standby mode.
