PORTABLE ELECTRONIC APPARATUS AND POWER MANAGEMENT METHOD THEREOF

摘要

A portable electronic apparatus and a power management method are provided. The portable electronic apparatus includes a power manager and a controller. The power manager is used to receive a supply power generated by a power adapter. The power manager determines whether to generate a detecting signal by detecting whether a voltage value variation of the supply power is greater than a preset range. The power manager generates a current detecting value according to an input current provided by the supply power. The controller receives the detecting signal and the current detecting value, and generates an input current limit value according to a receiving status of the detecting signal and the current detecting value. The power manager controls the input current according to the input current limit value.
