1. A power management method, applicable to an electronic device, wherein the electronic device is electrically coupled to an adapter and comprises a system and a battery, the adapter has a feed power, and the battery has a discharge power, the power management method comprising:
reading a power value of the battery;
determining a state of the system; and
discharging power to the system, when the system is in a power-on state and the power value is greater than a charging stopping value, by using the battery, and controlling, according to the discharge power and the feed power, the adapter to selectively supply power to the system,
wherein the charging stopping value represents a predetermined electricity quantity of the battery, and
wherein the system comprises a discharge protection unit, and the discharge protection unit has a discharge protection value, according to which a discharge protection function is selectively enabled, wherein when the system is in the power-on state, the power value is greater than the charging stopping value, and the discharge power is less than the feed power, the discharge protection value is adjusted.
