A method of operating a fan of a computing system includes: measuring a temperature of a subcomponent of the computing system; and comparing the temperature to a temperature threshold. When the temperature is greater or equal to than the temperature threshold, the fan is controlled based on a predetermined table of fan level settings. When the temperature less than the temperature threshold, a fan speed of the fan is measured. When the fan speed is not equal to zero, the method returns to the measurement of the temperature. When the fan speed is equal to zero, the fan is controlled based on a first power determination. The first power determination includes: measuring a system power level; and comparing the system power level to a trigger threshold. When the system power level is greater than the trigger threshold, the fan is activated to a predetermined setting.

Power system based fan control method

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.

An information processing apparatus and an information processing method capable of fulfilling an image processing function expected in a selected power control mode are provided. The information processing apparatus includes a first processor, a second processor, and a power control unit that determines one power control mode from among a plurality of stages of power control modes different in rated power, and controls power consumption of the first processor and the second processor in the determined power control mode, wherein the power control unit stops an operation of the second processor in response to the determined power control mode being a low power control mode which is a power control mode with the rated power lower than predetermined rated power.

An information processing apparatus includes: a controller that outputs notification information based on input information; and a processor that functions as a system processing unit that executes system processing based on an operating system (OS) and a Basic Input Output System (BIOS) processing unit that executes control related to the performance of the system processing by control of a BIOS using the notification information output from the controller.

Information processing apparatus and control method detecting a specific key combination pressed and activating a different mode of operation

An information processing apparatus includes a processor that can take plural power control modes different in rated power from one another, a fan that rotates to dissipate heat generated by the processor, and a power control unit that controls the power consumption of the processor. The plural power control modes include two or more stages of dynamic control modes different in rated power from one another and a unified communication mode. The power control unit selects any one of the dynamic control modes based on an event in which a power consumption state of the processor continues for a predetermined duration or more, and when the unified communication works, the power control unit preferentially selects the unified communication mode.

An information processing apparatus includes: a first chassis having a first surface provided with at least an air intake port; a second chassis which is connected to the first chassis in a relatively rotatable manner and has a second surface that overlaps the first surface of the first chassis by the rotation; a heat dissipation unit having a fan for replacing air in the first chassis with outside air through at least the air intake port; a state detection unit that detects whether a state is a first state in which the first surface and the second surface overlap; and a control unit which changes control of the fan according to whether the state is the first state.

One system apparatus, and method includes a processor that operates in at least a first power control mode including a first power amount and a second power control mode including a second power amount lower than the first power amount and a power control device. The power control device is configured to control power consumption in the processor, change a power control mode of the processor to the first power control mode in response to a first excess time period in which the power consumption of the processor exceeds a first reference power for a first period of time, and change the power control mode of the processor to the second power control mode in response to a second period of time in which the power consumption is less than or equal to a second reference power.

An information processing apparatus that detects processing to be executed by a processor includes: a display that displays a status of the processing to be executed by the processor; and a switching controller that switches between a first adjustment mode and a second adjustment mode in association with predetermined processing to be executed without displaying the execution status on the display. The first adjustment mode sets, as a target for selection, a first selection range including a plurality of processing power classes classified according to the magnitude of the processing power. The second adjustment mode sets, as a target for selection, a second selection range in which a first processing power class related to relatively high processing power is excluded from among the first processing power class, a second processing power class, and a third processing power class of the first selection range.
