The main body 203 of electronic equipment；A part for mechanical switch can also be placed in the display screen 201 of electronic equipment, it is mechanical to open
Another part of pass is placed in the main body 203 of electronic equipment；Then, by obtaining the relative position of position sensor or mechanical switch
Put, to obtain the display screen 201 of electronic equipment and the relative position of main body 203.
The number of applications that electronic equipment can also be currently operating on electronic equipment by detection obtains electronic equipment
Current state.When it is 10 that the application program run on electronic equipment, which pre-sets quantity, if operating in answering for electronic equipment
With program quantity more than 10, electronic equipment is in first state；If operating in the number of applications of electronic equipment less than 10
Individual, electronic equipment is in the second state.
Certainly, pre-setting quantity for application program in the present embodiment can also be set by user, such as 8, or 12, this hair
It is bright not to be restricted.
Electronic equipment according to the operation received, can also obtain the current state of electronic equipment.Such as：Electronic equipment is received
To the first operation for entering first state, such as during CTRL++, just determine that electronic equipment is in first state；Electronic equipment is received
To the second operation such as CTRL for entering the second state --- when, just determine that electronic equipment is in the second state.
In step 102：Whether judge current state is first state or the second state.
Continue along using an example, for example, can by judge electronic equipment display screen 201 and main body 203 it is relative
Whether position is in the first predetermined angle or the second predetermined angle scope judges whether current state is first state or second
State, specifically, by judging the angle between the display screen 201 of electronic equipment and main body 203 whether in the first predetermined angle
In the range of when, to determine that electronic equipment is for first state or the second state, such as：When corresponding first preset angle of first state
When degree scope is spent for 0-180, and in the angle corresponding with the relative position of main body 203 of display screen 201 for detecting electronic equipment
During for 180 degree, it is possible to determine that electronic equipment is in first state, in the embodiment of the present application, first state is specially pen
Remember this computer state；When the corresponding second predetermined angle scope of the second state is spent for 181-360, and detecting electronic equipment
Display screen 201 and main body 203 between angle be 360 degree, it is possible to determine electronic equipment be in the second state, in the application
In embodiment, the second state can be tablet personal computer state.
Can also be by judging whether the display screen 201 of electronic equipment and the relative position of main body 203 are preset by first
Angle adjustment judges that electronics is set to the second predetermined angle or by the second predetermined angle scope is adjusted to the first predetermined angle scope
Whether standby current state is first state or the second state, specifically, by the display screen 201 and main body that judge electronic equipment
Whether the angle between 203 is adjusted to the second predetermined angle by the first predetermined angle, such as when being adjusted by 0 degree to 90 degree, electricity
Sub- equipment is in notebook computer state；When the angle between display screen 201 and main body 203 by the second predetermined angle adjust to
In first predetermined angle, such as when being adjusted by 180 degree to 360 degree, electronic equipment is in tablet personal computer state.
Electronic equipment area is in first state, or second state different from first state, and can also run on electricity
Number of applications in sub- equipment is related.For example：The first preset value, example are met when running on the application program on electronic equipment
Such as whether judge whether electronic equipment is first state or the second state more than or equal to 10, when run on electronic equipment should
When being more than or equal to 10 with program quantity, electronic equipment is in first state, when running on the number of applications on electronic equipment
During less than 10, electronic equipment is in the second state.
Electronic equipment is to be in first state, or second state different from first state, can also be by electronic equipment
Whether first operation is received related, for example, when detecting the first button operation, electronic equipment correspondence first state works as inspection
When measuring the second button operation different from the first button operation, electronic equipment the second state of correspondence, such as user can basis
Need to input the first operation, such as CTRL++ in the electronic device, it is determined that electronic equipment is in notebook computer state, user
The second operation, such as CTRL can also be inputted in the electronic device as needed ---, it is determined that electronic equipment is in flat board pen
Remember this computer state.
Step 103：If current state is first state, the first control instruction is generated, if current state is the second state
When, generate the second control instruction.
Continue along an embodiment is used, if electronic equipment current state is first state, generation the first control instruction example
Such as high level signal, if electronic equipment current state is the second state, the second control instruction such as low level signal is generated.
Step 104：The first control instruction is performed, CPU working frequency is controlled within the first maximum operation frequency, or
The second control instruction is performed, CPU working frequency is controlled within the second maximum operation frequency, specifically, first is performed and controls
System instruction, exports the first maximum functional clock, so that CPU working frequency is controlled within the first maximum operation frequency, wherein
First maximum functional clock is corresponding with the first maximum operation frequency；Or the second control instruction is performed, during the second maximum functional of output
Clock, so that CPU working frequency is controlled within the second maximum operation frequency, wherein the second maximum functional clock and the second maximum
Working frequency correspondence.
Continue along an embodiment is used, electronic equipment performs high level signal, exports the first maximum functional clock t1, so that
CPU working frequency is controlled within the first maximum operation frequency f1, wherein the maximum works of the first maximum functional clock t1 and first
Working frequency f1 relational expression is f1=c/t1, and wherein c is constant.Electronic equipment performs low level signal, exports the second maximum functional
Clock t2 so that CPU working frequency control within the second maximum operation frequency f2, wherein the second maximum functional clock t2 with
Second maximum operation frequency f2 relational expression is f2=c/t2.
If electronic equipment current state is first state, due to electronic equipment in first state it is corresponding first maximum
Working frequency is big, so electronic equipment power consumption in first state is big, heat dissipation capacity is high, and electronic equipment works long hours first most
Big working frequency may result in CPU failures.
If electronic equipment current state is the second state, due to electronic equipment in the second state it is corresponding second maximum
Working frequency is small, so electronic equipment can reduce process resource waste in the second state, cpu busy percentage is improved, due to CPU
Working frequency is small, small power consumption, and then heat dissipation capacity is low, can solve the problem that the problem of caloric value is high, increases the service life.
