Abstract

The present invention provides a control method applied to electronic equipment, the electronic equipment includes an operating system, BIOS, EC and CPU, the method includes: based on the electronic equipment being in a normal working state, receiving the first system information sent by the operating system of the electronic equipment signal, the first system signal is used to control the screen off of the electronic device; based on the screen off of the electronic device, control the BIOS to send a first instruction to the EC, so that the EC will change the maximum power consumption value of the CPU from a larger The first numerical value of is set to a smaller second numerical value and the fan is controlled to be turned off, so as to control the electronic device to enter the first state. In this scheme, when the screen of the electronic device is turned off, it enters a dormant state for the user, and at this time, the control reduces the maximum power consumption value of the CPU, so that the power consumption of the CPU is reduced, its temperature is lowered, and the fan is turned off. , to reduce the noise of the fan, that is, after the device enters the sleep state, the noise of the electronic device is reduced as a whole, and the user experience is improved.

Description

technical field

[0001] The present invention relates to the field of electronic equipment, and more specifically, relates to a control method and device. Background technique

[0002] With the development of electronic technology, electronic devices can switch between various functional states, so that the electronic devices can run different applications in different functional states.

[0003] For example, the electronic device is equipped with a MS (Modern Standby, new sleep mode) (AOAC, always on line always connect, always on line always connected) function, which can achieve a networked state when the electronic device is in the MS state.

[0004] However, after the electronic device enters the MS state, it will complete some necessary work, such as system update, network task download, and music playback. At this time, due to the excessive power consumption of the CPU (central processing unit, central processing unit) High, resulting in a lot of fan noise, for the us...
