Abstract
An electronic device including a control unit, an embedded controller and a battery module is provided. During a booting procedure of the electronic device, the embedded controller reads a reported battery capacity and a battery temperature of the battery module. The embedded controller determines whether the reported battery capacity is lower than a minimum capacity, and further determines whether the battery temperature is lower than a minimum temperature when the reported battery capacity is lower than the minimum capacity. When the reported capacity is lower than the minimum capacity and the battery temperature is also lower than the minimum temperature, the embedded controller generates a fake battery capacity, according to which an operating system of the electronic device performs various operations. In this application, the battery module of the electronic device remains working even when the electronic device is in a low-temperature and low-battery activation environment.
