Abstract

The invention relates to an electronic device and a power supply management method thereof. According to the power supply management method of the electronic device, the electronic device is provided with an internal power supply and a battery management unit; and the power supply management method comprises the following steps that: the battery management unit detects whether the electronic device is electrically connected with an external power supply or not; if the electronic device is electrically connected with the external power supply, the battery management unit judges whether the electrical connection time of the electronic device and the external power supply reaches preset time or not by using a timer; and if the electrical connection time of the electronic device and the external power supply reaches the preset time, the battery management unit resets the timer and controls the internal power supply to quickly discharge. According to the power supply management method, the intelligent maintenance management is applied to the internal power supply, thus, the aim of prolonging the service life of the internal power supply is achieved through effectively avoiding the situation that users neglect to maintain the internal power supply.

Description

technical field [0001] The present invention relates to an electronic device and its power management method, and in particular to an intelligent electronic device and its power management method. Background technique [0002] Nowadays, more and more users purchase portable electronic devices, including notebook computers, which have the advantage of being available anytime and anywhere regardless of the location, not only providing users with high convenience, but also bringing users the pleasure of instant use while moving. Among the components of notebook computers, batteries are expensive consumables. If the service life of the battery is longer, the user's use cost will be lower. [0003] Therefore, how to manage the battery of the notebook computer to maintain the activity of the battery and improve the service life of the battery is an important issue in the industry at present. Contents of the invention [0004] The invention relates to an electronic device and a...
