Abstract: A power management system is disposed in a computer. The power management system includes a current detecting module and a chipset. The current detecting module is disposed between the power receiving end of an external device and the power cord of the power source of the computer for detecting the current sink by the external device and accordingly outputting a current detecting signal. The chipset adjusts the operating voltage or operating frequency of the external device according to the current detecting signal.

Abstract: A system for compensating the characteristics of a fan, applied to a heat-dissipating fan of an electronic device. This system comprises of an analyzing module for analyzing the relation between the duty ratio of pulse width modulation (PWM) and the rotational speed of the fan to generate analyzing data, and a compensating module for generating compensating data basing on the analyzing data and a specific proportion relation between the temperature and the duty ratio of PWM.

Abstract: The invention provides a voltage-controlled device, method and computer device capable of dynamically regulating voltage and effectively saving energy. The voltage-controlled device receives a VID from a CPU, determines a core voltage according to a load line defined therein, and supplies the core voltage to the CPU. The voltage-controlled device has a load line register set and a write logic. The load line register set has a plurality of registers, and the values of which represent the defined load line. The write logic changes the values of the registers in the load line register set according to a write signal.

Abstract: An integrated connecting port module is suitable for an adapter having one terminal which is a High Definition Multimedia Interface (HDMI) adapting port and the other terminal which is a Digital Visual Interface (DVI) adapting port. The integrated connecting port module includes a case, an HDMI port and at least one expansion port. The case has a width not smaller than that of the DVI adapting port. The HDMI port and the expansion port are installed on the case and are stacked. An electronic device including the integrated connecting port module is also disclosed.

Abstract: A motherboard with a switching function has a substrate, a chipset, a control signal generator, an on-board device, an extension slot, and a switching circuit module. The switching circuit module disposed on the substrate has a first terminal connected to the chipset for receiving a input signal from the chipset, a second terminal for receiving a control signal from the control signal generator, a first output circuit connected to the first on-board device, and a second output circuit connected to the first extension slot. The control signal determines a turned on state of the first switch output circuit and the second output circuit.
