An electronic device includes a first module including a first conductive component and a power control unit coupled to the first conductive component. The electronic device further includes a second module, a first hinge for pivoting the second module relative to the first module, and a first arm connected to the first hinge. The power control unit controls whether to execute a first power management status according to whether the first arm contacts the first conductive component as the second module pivots relative to the first module at a first angle by the first hinge.
