Abstract

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.

First claim

What is claimed is:

1. An apparatus comprising:
an execution unit of an information processing device configured to execute an operation related to an initial setting mode of the information processing device;
a power supply configured to supply power to one or more heat generating components of the execution unit; and
a controller configured to control 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, wherein the fulfillment of the predetermined condition comprises elapsing of a period for the execution unit to perform initial setting mode processing after a first boot of the information processing device that includes booting an operating system in an initial state.

2. The apparatus of claim 1 , wherein the fulfillment of the predetermined condition further comprises the execution unit terminating processing related to a system configuration of the information processing device.

3. The apparatus of claim 1 , further comprising:
a processor configured to perform initial setting mode processing,
wherein the controller controls the power supply to make the power supplied to the processor lower than a reference power until the fulfillment of the predetermined condition.

4. The apparatus of claim 3 , wherein
the execution unit includes a cooling fan that cools the processor, and
the controller controls the cooling fan to make a maximum rotational speed of the cooling fan lower than a reference upper limit rotational speed until the fulfillment of the predetermined condition.

5. The apparatus of claim 3 , wherein the power supplied is set to limit a required increase in time for the processor to complete the initial setting mode processing with respect to a required time to supply the reference power to the processor in order to complete the initial setting mode processing to 10% or less.

6. The apparatus of claim 3 , wherein the power supplied is 70% of the reference power or more.

7. The apparatus of claim 3 , wherein the controller controls the power supplied so that an increase in time required for the processor to complete the initial setting mode with respect to the time required to supply the reference power to the processor in order to complete the initial setting mode falls within a predetermined range.

8. The apparatus of claim 1 , wherein in response to the information processing device transitioning to a predetermined power-saving mode, the controller supplies, to the execution unit, power set in the predetermined power-saving mode including during the period for performing initial setting mode processing.

9. A method comprising:
supplying power to one or more heat generating components of an execution unit of an information processing device;
executing an operation related to an initial setting mode of an information processing device; and
controlling at least power supplied to the execution unit to make a first amount of heat generation of the execution unit in the initial setting mode lower than a second amount of heat generation of the execution unit in the different operating mode after termination of the initial setting mode until fulfillment of a predetermined condition, wherein the fulfillment of the predetermined condition comprises a period for the execution unit to perform initial setting mode processing elapsing after a first boot of the information processing device that includes booting an operating system in an initial state.

10. The method of claim 9 , wherein the fulfillment of the predetermined condition further comprises terminating processing related to a system configuration of the information processing device.

11. The method of claim 9 , further comprising controlling a cooling fan for cooling the execution unit to make a rotational speed of the cooling fan lower than a reference upper limit rotational speed until the fulfillment of the predetermined condition.

12. The method of claim 9 , further comprising controlling the power supplied to limit a required increase in time for the processor to complete the initial setting mode with respect to a required time to supply the reference power to the processor in order to complete the initial setting mode to 10% or less.

13. The method of claim 9 , further comprising controlling the power supplied to be 70% of the reference power or more.

14. A program product comprising a non-transitory machine readable storage medium that stores code executable by a processor, the executable code comprising code to:
supplying power to one or more heat generating components of an execution unit of an information processing device;
executing an operation related to an initial setting mode of an information processing device; and
control at least power supplied to the execution unit to make a first amount of heat generation of the execution unit in the initial setting mode lower than a second amount of heat generation of the execution unit in the different operating mode after termination of the initial setting mode until fulfillment of a predetermined condition, wherein the fulfillment of the predetermined condition comprises a period for the execution unit to perform initial setting mode processing elapsing after a first boot of the information processing device that includes booting an operating system in an initial state.
