Patent number: 11586263Abstract: 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.Type: GrantFiled: September 30, 2021Date of Patent: February 21, 2023Assignee: LENOVO (SINGAPORE) PTE.
