Abstract
The present invention discloses an electronic device having a power management module and a power management method thereof. Within the power management method is used for an electronic device, which has a first power module, a second power module and the loads. The power management method comprises the following step: (1) monitoring the first power module and the second power module; (2) if the first power module and the second power module are activated at the same time, sequentially stopping a supply of electric power to at least one of the loads until the electronic device has total load current smaller than a reference value.
