Leakage detection device, leakage detection method and related computer system

Abstract

A leakage detection device for a computer system, includes a current generation circuit, coupled to a power line of a motherboard of the computer system, configured to generate a detection current; a voltage detection circuit, coupled to the power line, configured to detect a voltage value of the power line; and a control unit, coupled to the current generation circuit and the voltage detection circuit. When the computer system enters a first operating mode, the control unit controls the current generation circuit to output the detection current to the power line, and controls the voltage detection circuit to detect the voltage value of the power line, in order to determine a voltage variation curve of the power line relative to the detection current, and determines whether a leakage event occurs on the motherboard based on a voltage slope of the voltage variation curve.
