Claim:
1. A power management method, applicable to an electronic device comprising a controller, a processor and a battery, the power management method comprising: in a hybrid power mode, providing a first power to the electronic device by a power adapter and providing a second power to the electronic device by the battery, wherein a maximum value of the first power is smaller than a maximum value of a rated consumed power required by the electronic device; providing the electronic device with power through the first power and the second power simultaneously; when the electronic device is provided with power through the first power and the second power simultaneously, decreasing a clock frequency of the processor in response to determining that a system voltage of the power adapter is abnormal; in response to decreasing the clock frequency of the processor, obtaining a discharge current or a remaining capacity of the battery in the electronic device provided with power through the first power and the second power simultaneously; generating a control signal according to a power state of the second power by the controller and adjusting the clock frequency of the processor by the processor based on the control signal; and continuously adjusting the clock frequency of the processor according to the power state of the second power of the battery.
