Abstract: The fan controlling method comprises following steps: Firstly, a current rotation speed of a fan is obtained. Next, whether the current rotation speed is not greater than an expected rotation speed corresponding to the first type is determined. Then, whether a rotation speed variance between the current rotation speed and the expected rotation speed is not greater than a reasonable variance is determined when the current rotation speed is not greater than the expected rotation speed. Then, a determination that the fan belongs to the first type is made when the rotation speed variance is not greater than the reasonable variance, and a determination that the fan belongs to the second type is made when the rotation speed variance is greater than the reasonable variance, wherein the second type is different from the first type.

Abstract: A portable electronic apparatus and a power management method are disclosed. The portable electronic apparatus comprises a processor and an embedded controller (EC). The EC determines whether the processor starts a throttling mechanism according to a current power consumption, a proportional term, a last power consumption, a lower bound, a delta power and a derivative term. The EC determines whether the processor cancels the throttling mechanism according to the current power consumption, the lower bound, a count that the power consumption is lower than the lower bound, and an integral term.

Abstract: A power management method for a computer system is provided. The power management method includes: obtaining a system power consumption; determining whether the system power consumption is greater than a first safe operating point; when the system power consumption is greater than the first safe operating point, controlling a CPU and a graphics processing unit (GPU) to activate a frequency reduction mechanism according to a first adjustment sequence; when the system power consumption is not greater than the first safe operating point, determining whether the system power consumption is smaller than a second safe operating point; and when the system power consumption is smaller than the second safe operating point, controlling the CPU and the GPU to deactivate the frequency reduction mechanism according to a second adjustment sequence. The second adjustment sequence is reverse to the first adjustment sequence.
