Problems solved by technology

[0004] When the USB Type-C interface is used to power the mobile terminal, the initial output setting is 3A current output, and the power supply current is relatively large. At this time, if the CPU of the notebook computer has a large operating frequency at the same time, it may cause the notebook computer to be overloaded. , that is, the actual discharge power of the power supply unit of the notebook computer will be greater than the maximum discharge power of the power supply unit
In order to avoid damage to the power supply unit of the notebook computer, the prior art generally limits the total power of the system by reducing the CPU frequency of the notebook computer, thereby causing the performance of the notebook computer to decrease

Abstract

The invention discloses an electronic device and a control method; the electronic device comprises a CPU (central processing unit), a power control system connected to the CPU, and a discharge port connected to the power control system and used for powering an external device, wherein the power control system is used for generating a CPU frequency-lowering command when the electronic device is overloaded, judging whether the CPU frequency-lowering command meets first conditions or not, and maintaining working frequency of the CPU if yes so that output power of the output port is lowered. According to the technical scheme, the performance of the electronic device is never decreased at the premise of powering a mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, and more specifically, relates to an electronic equipment and a control method. Background technique [0002] With the continuous development of science and technology, notebook computers are more and more widely used in people's daily life and work, bringing great convenience to people's daily life and work, and becoming an indispensable tool for people today. [0003] With the popularization of mobile terminals such as mobile phones, at least one USB Type-C interface (USB C interface for short) is integrated on the notebook computer, so as to provide power for the mobile terminal or perform data interaction with the mobile terminal. [0004] When the USB Type-C interface is used to power the mobile terminal, the initial output setting is 3A current output, and the power supply current is relatively large. At this time, if the CPU of the notebook computer has a high operatin...
