发明名称 Method and system of controlling power supply of an information processing device including load information
摘要 An information processing device is provided. The information processing device which operates upon receipt of power supply from a power unit connected to an alternative current power source or from a battery includes an obtaining unit which obtains load information of parts included in the information processing device itself, a deciding unit which decides a voltage value to be supplied by the power unit which supplies electric power to the information processing device, based on the load information obtained by the obtaining unit, and an output unit which outputs a signal relative to the voltage value decided by the deciding unit to the power unit.

主权项 1. An information processing device comprising: a first voltage converter; and a processor that executes a procedure including: obtaining total load information for the information processing device including output currents obtained for at least one device in the information processing device; deciding a voltage value to be output by a second converter, based on an average calculated for the output currents associated with the total load information, the second converter outputting an output voltage, the first voltage converter receiving and converting a voltage based on the output voltage of the second voltage converter; and outputting a signal to the second voltage converter and corresponding to the voltage value decided by the deciding; the at least one device in the information processing device includes a plurality of devices, and the deciding utilizes the average calculated from the total load information with respect to the plurality of devices in an expression to decide the voltage value to be output, wherein the deciding includes: referring to a conversion table which stores voltage values in accordance with the average calculated for the total load information regarding the plurality of devices, and deciding the output value based on the referring.
