Information processing apparatus, control method, and program product

A method comprising:

• measuring the temperature of a predetermined measurement point to be measured in an information processing apparatus which includes at least two devices, each device having at least two operation modes corresponding to the power consumption and the processing speed thereof;
• selecting a device to be minimized the degradation in processing performance if an operation mode is changed from first operation mode to second operation mode in which the power consumption and/or the processing speed are lower than those in the first operation mode to lower the temperature of the measurement point in a case that the measured temperature is equal to or higher than a predetermined reference temperature;
• and
• changing the operation mode of the selected device from the first operation mode to the second operation mode.

A product comprising:

• a computer usable medium having computer readable program code stored therein for controlling heat generation of an information processing apparatus which includes at least two devices, each device having at least two operation modes corresponding to power consumption and/or processing speed thereof, the computer readable program code in said product being effective to:
• measure temperature of a predetermined measurement point to be measured in the apparatus;
• select a device to be minimized the degradation in processing performance if an operation mode is changed from the first operation mode to the second operation mode in which the power consumption and/or the processing speed are lower than those in the first operation mode to lower the temperature of the measurement point in a case that the measured temperature is equal to or higher than a predetermined reference temperature;
• and
• change the operation mode of the selected device from the first operation mode to the second operation mode.
