Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Accompanying drawing 1 is referred to, is a kind of flow chart of control method embodiment 1 provided by the invention, this method is applied to one
In electronic equipment, also, the electronic equipment include operating system, BIOS (Basic input/output system, it is substantially defeated
Enter output system), EC (Electronic Computer, embedded controller) and CPU.Wherein, the operating system specifically may be used
With using windows operating systems etc..
Wherein, this method includes：
Step S101：Normal operating conditions is in based on the electronic equipment, the operating system for receiving electronic equipment is sent
The first system signal, the first system signal be used for control the screen of the electronic equipment to close；
Wherein, when the electronic equipment is in normal operating conditions, its screen is in opening, i.e. bright screen, shows in screen
Show content.
In specific implementation, after the first system signal of operating system transmission is received, then according to the first system signal
The screen of the electronic equipment is controlled to close.
Specifically, the user that the first system signal can be electronic equipment performs specific operation triggering, as user presses
Button with " dormancy " function or the cover closing of electronic equipment screen (when such as the electronic equipment is notebook type, is held
Row closes the operation of the notebook computer), or the operation of electronic equipment meets to trigger during specified conditions, such as preset time
For user without operation, the electronic equipment automatically switches to " dormancy " of screen closing in section.
Step S102：Screen based on the electronic equipment is closed, and control BIOS sends first and instructed to EC, to cause
EC is stated the maximum power dissipation value of the CPU is arranged into second value from the first numerical value according to the described first instruction and controls closing
Fan, the second value are less than first numerical value, control the electronic equipment to enter first state to realize.
Wherein, after the screen of the electronic equipment is closed, the electronic equipment needs to enter park mode, at this time, it may be necessary to drop
The noise of low fan, to realize the low sensory experience of the electronic equipment noise for a user.
Specifically, after the electronic equipment screen is closed, operating system can control the BIOS to generate and send the first instruction
To EC, the EC is notified to learn the situation that the electronic equipment screen is closed to realize.
Then, the EC according to this first instruction adjust the CPU maximum power dissipation value from the first larger numerical value be arranged to compared with
Small second value, to cause the lower power consumption of the CPU, reduce its temperature.
In specific implementation, the first numerical value of the maximum power dissipation value of the CPU can be bigger numerical, such as 25W, so that realize can
Power consumption is provided to multiple applications；The second value of its maximum power dissipation value can be compared with fractional value, such as 2W, can be only specific several
Individual application provides power consumption.
In specific implementation, the maximum power dissipation value of the CPU is also referred to as PL1 (Power limit 1, single order power consumption limit).
Also, the EC closes fan always according to the first instruction control, reduces the noise of fan.
It should be noted that due to the lower power consumption of the CPU, its temperature accordingly reduces, then cools without the fan for it,
So fan is closed on the premise of relatively low in guarantee cpu temperature, the operation without influenceing CPU.
It should be noted that first instruction can specifically use I/O (input/output, input and output) instruction side
Formula.
In specific implementation, the EC controls the rotating speed of fan by pulse width modulating signal, and the closing fan specifically may be used
Realized in a manner of using fan power supply is closed.

With in running, network information transfer can be carried out, can also be without network information transfer；Or the default application stops
Only run, then it can also not have network information transfer.
Wherein, when the default application does not have network information transfer, then it can determine that the default application is not carried out higher power dissipation
Operation, at this point it is possible to determine that the power consumption needed for the CPU is relatively low, determine that the operating system of the electronic equipment enters the second state.
It should be noted that the electronic equipment (operating system of electronic equipment in other words) has two states：Blank screen, most
Big power consumption number is the first state that second value and fan are closed, blank screen, maximum power dissipation value be second value, fan close and
It is default to apply the second state without network information transfer.
In specific implementation, the first state can be named as MS active and (software dormancy shape be activated in new sleep pattern
The state of state), the second state can be named as MS SW drips (software resting state in new sleep pattern).
Step S204：Operating system described in control BIOS notices EC enters the second state, to cause the EC from Working mould
Formula enters park mode.
Wherein, after operating system enters the second state, operating system continues to control BIOS to notify EC that it enters second
State.
Then, the content of EC notices enters park mode from mode of operation, to cause some applications of the EC (or work(
Can) out of service, cause the lower power consumption of the EC, to realize the temperature for reducing the electronic equipment.
In specific implementation, the park mode is specifically as follows Doze mode (system doze mode).
To sum up, in a kind of control method that the present embodiment provides, in addition to：Passed based on the default no network information of application
It is defeated, judge that the operating system enters the second state；Operating system described in control BIOS notices EC enters the second state, to cause
The EC enters park mode from mode of operation.In the program, on the premise of CPU maximum power dissipation value is reduced, close fan,
EC state is further switched into park mode from mode of operation, to cause the lower power consumption of the EC, further reduces the electricity
The temperature of sub- equipment.
