All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of an embodiment 1 of a control method according to the present invention is shown, where the method is applied to an Electronic device, and the Electronic device includes an operating system, a BIOS (Basic input/output system), an EC (Electronic Computer), and a CPU. The operating system may specifically adopt a windows operating system and the like.
Wherein, the method comprises the following steps:
step S101: receiving a first system signal sent by an operating system of the electronic equipment based on the fact that the electronic equipment is in a normal working state, wherein the first system signal is used for controlling a screen of the electronic equipment to be closed;
when the electronic equipment is in a normal working state, the screen of the electronic equipment is in an open state, namely the screen is lightened, and the content is displayed in the screen.
In specific implementation, after receiving a first system signal sent by an operating system, the screen of the electronic device is controlled to be closed according to the first system signal.
Specifically, the first system signal may be triggered by a user of the electronic device performing a specific operation, such as pressing a button with a "sleep" function by the user, or closing a cover of a screen of the electronic device (for example, when the electronic device is a notebook computer, an operation of closing the notebook computer is performed), or triggered when the operation of the electronic device meets a specific condition, such as no operation by the user in a preset time period, and the electronic device is automatically switched to a "sleep" mode in which the screen is closed.
Step S102: based on the screen of the electronic equipment is closed, the BIOS is controlled to send a first instruction to the EC, so that the EC sets the maximum power consumption value of the CPU from a first value to a second value according to the first instruction and controls the fan to be closed, and the second value is smaller than the first value, so that the electronic equipment is controlled to enter a first state.
After the screen of the electronic device is turned off, the electronic device needs to enter a sleep mode, and at this time, the noise of the fan needs to be reduced, so as to realize the sensory experience of low noise of the electronic device for the user.
Specifically, after the screen of the electronic device is closed, the operating system can control the BIOS to generate and send a first instruction to the EC, so as to notify the EC of knowing that the screen of the electronic device is closed.
Then, the EC adjusts the maximum power consumption value of the CPU according to the first instruction, and sets the maximum power consumption value of the CPU from a larger first value to a smaller second value, so that the power consumption of the CPU is reduced, and the temperature of the CPU is reduced.
In a specific implementation, the first value of the maximum power consumption value of the CPU may be a larger value, such as 25W, so as to provide power consumption for multiple applications; the second value of the maximum power consumption value may be a small value, such as 2W, and may provide power consumption for only a specific number of applications.
In a specific implementation, the maximum Power consumption value of the CPU is also referred to as PL1(Power limit 1, first order Power limit).
And the EC controls the fan to be turned off according to the first instruction, so that the noise of the fan is reduced.
It should be noted that, because the power consumption of the CPU is reduced and the temperature thereof is correspondingly reduced, the fan is not required to cool the CPU, and therefore, the fan is turned off on the premise of ensuring that the temperature of the CPU is low, and the operation of the CPU is not affected.
It should be noted that the first instruction may specifically adopt an I/O (input/output) instruction mode.
In a specific implementation, the EC controls the rotation speed of the fan through a pulse width modulation signal, and the fan can be turned off specifically by turning off the power supply of the fan.
In summary, the present embodiment provides a control method, including: receiving a first system signal sent by an operating system of the electronic equipment based on the fact that the electronic equipment is in a normal working state, wherein the first system signal is used for controlling a screen of the electronic equipment to be closed; based on the screen of the electronic equipment is closed, the BIOS is controlled to send a first instruction to the EC, so that the EC sets the maximum power consumption value of the CPU from a first value to a second value according to the first instruction and controls the fan to be closed, and the second value is smaller than the first value, so that the electronic equipment is controlled to enter a first state. In the scheme, when the screen of the electronic equipment is closed, the electronic equipment enters a dormant state relative to a user, the maximum power consumption value of the CPU is controlled to be reduced, so that the power consumption of the CPU is reduced, the temperature of the CPU is reduced, the fan is turned off, the noise of the fan is reduced, namely after the equipment enters the dormant state, the noise of the electronic equipment is reduced on the whole, and the user experience is improved.

Step S204: the control BIOS notifies the EC of the operating system entering a second state to cause the EC to enter a sleep mode from an operating mode.
After the operating system enters the second state, the operating system continues to control the BIOS to notify the EC that it entered the second state.
The contents of the EC notification are then put from an active mode into a sleep mode to cause certain applications (or functions) of the EC to cease functioning, resulting in a reduction in power consumption of the EC to achieve a reduction in the temperature of the electronic device.
In a specific implementation, the sleep mode may be a Doze mode (system Doze mode).
