Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an information processing apparatus and a control method. Description of the Related Art In an information processing apparatus such as a personal computer (PC), in a case where performance is emphasized, performance per watt (Perf/Watt) efficiency deteriorates, and problems such as wasteful power consumption, noise of a heat dissipation fan, and an increase in temperature of a chassis may occur. In order to solve such a problem, in recent years, an attempt has been made to operate an information processing apparatus by providing a power limit to balance between performance and power consumption (for example, refer to Japanese Patent No. 7521065). SUMMARY OF THE INVENTION However, in the information processing apparatus, for example, since various tasks are processed and the operating state is constantly changed, it is difficult for the information processing apparatus in the related art to operate the information processing apparatus in an appropriate state in which a balance between performance and power consumption is achieved. The present invention has been made in order to solve the above-described problem, and an object of the present invention is to provide an information processing apparatus and a control method that can operate in an appropriate state in which a balance between performance and power consumption is achieved. In order to solve the above problem, an information processing apparatus according to a first aspect of the present invention includes: an input unit configured to receive input from a user; a main control unit configured to execute information processing such that a set limit value of power consumption is not exceeded; an input delay detection unit configured to detect a delay time from the input received by the input unit to output to a display unit; and a power control unit configured to control the limit value of the power consumption such that the delay time falls within a predetermined range according to the delay time detected by the input delay detection unit. In addition, in the information processing apparatus according to the first aspect, the limit value of the power consumption may be settable in a plurality of stages, and the power control unit may be configured to change the stage of the limit value of the power consumption according to the delay time and control the limit value of the power consumption. In addition, in the information processing apparatus according to the first aspect, the power control unit may be configured to change the stage in a direction of decreasing the limit value of the power consumption in a case where the delay time is faster than the predetermined range, and change the stage in a direction of increasing the limit value of the power consumption in a case where the delay time is slower than the predetermined range. In addition, in the information processing apparatus according to the first aspect, the power control unit may be configured to change the number of stages to be changed according to a degree to which the delay time is out of the predetermined range.
