Abstract: A system loading detecting device and method are provided. The system loading detecting device includes a processing device, a detection circuit and a controller. The detection circuit detects whether an adapter is unplugged from the system loading detecting device to generate a detection signal. When the adapter is unplugged from the system loading detecting device, the detection signal is changed from a first level to a second level. The controller is coupled to the detection circuit and the processing device. In addition, the controller receives the detection signal and determines whether to trigger the generation of a throttling signal according to the detection signal to enable a throttling mechanism to reduce system loading.

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.
