The invention provides an electronic device, which comprises a mainboard and a handwriting pen; the mainboard comprises a plurality of triggers, a memory, a plurality of power consumption modules, a pen cap, a power supply control module and a power supply module; the pen cap is used for accommodating the handwriting pen; the memory memorizes a relation table which records the correspondence relation of the triggers and the power consumption modules; the handwriting pen comprises a refill part of which a protruded positioning column is formed on the circumferential surface; and when one or more of the plurality of triggers are triggered by the positioning column of the handwriting pen inserted in the pen cap, the power supply control module identifies the triggered triggers, reads the relation table in the memory, and controls the power supply module to supply power to the power consumption modules which correspond to the triggered triggers. The electronic device rationally utilizes the electric quantity of a battery.
Description
technical field [0001] The invention relates to an electronic device, in particular to an electronic device with a stylus. Background technique [0002] A common electronic device, such as a mobile phone, has a plurality of modules, such as a Bluetooth module, on its main board. The above-mentioned modules have different power consumption levels. [0003] Generally, when the battery on the electronic device supplies power to the electronic device, it directly supplies power to all the modules on the electronic device as a whole. However, if the power of the battery on the electronic device is insufficient, if power is still supplied to all the modules on the electronic device, some modules cannot continue to work due to the insufficient power. Therefore, it is necessary to propose an electronic device that can selectively supply power to some modules on the electronic device according to the user's needs, so that the power on the battery can be reasonably utilized.
