Embodiment
For making the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the accompanying drawings and the specific embodiments.
With reference to Fig. 1, the method preventing notebook computer overheated of the embodiment of the present invention, comprises the steps:
Step 101: the temperature detecting described notebook computer within predetermined time interval, obtains the first temperature;
Detect environment temperature in described notebook computer by arranging temperature-sensing element in notebook computer, such as, can under keyboard, top, CPU position arranges described temperature-sensing element.The time interval can be arranged as required, such as, arranges every 5 minutes and carries out a temperature sampling.
Step 102: judge whether described first temperature is greater than predetermined temperature, produces the first judged result;
In BIOS, system protection point is generally 90 degree, and in the present embodiment, preferentially, described in the ratio arranged by described predetermined temperature, system protection point is low, such as, is set to 60 degree, 70 degree, 75 degree etc.
Step 103: when described first judged result represents that described first temperature is greater than described predetermined temperature, till determining current time, described first temperature is greater than the frequency of described predetermined temperature;
As long as detect that temperature adjusts different higher than system protection point with regard to carrying out duty immediately from prior art; the embodiment of the present invention utilizes multiple judged result to determine the duty of notebook computer; it is more accurate for opportunity to make the adjustment of working with notebook computer state; and; the duty that the combination of different judged result is corresponding different, makes adjustment mode more flexibly effectively.
Exemplarily, described to current time, described first temperature is greater than the frequency of described predetermined temperature, specifically comprises: by representing that described first temperature is greater than the value increase by 1 of the counter of the number of times of described predetermined temperature, obtain described frequency.
Exemplarily, the embodiment of the present invention provides the following two kinds counting mode: (1) is counted by counter, when described first temperature is greater than described predetermined temperature, the count value of described counter is increased by 1, obtains described frequency.(2) counted by a numeric type variable, when described first temperature is greater than described predetermined temperature, the value of this variable is increased by 1, obtains described frequency.
Step 104: determine first duty corresponding with described frequency;
The corresponding relation of described frequency and described first duty can be pre-set, such as, set up following mapping table:
| Frequency | First duty |
| 2 | CPU frequency reducing |
| 4 | System hibernates (S3) |
| 5 | System depth dormancy (S4) |
| 8 | System closedown (S5) |
As can be seen from above mapping table, when the situation that measuring tempeature is greater than described predetermined temperature only occurs one time, system can not do any process, and only when the situation that measuring tempeature is greater than described predetermined temperature occurs repeatedly, just have corresponding process means (as CPU frequency reducing, system hibernates, system depth dormancy and shutdown etc.).
Certainly, above-mentionedly only to illustrate, it is also passable by frequency to be that the action of 1 correspondence is set to CPU frequency reducing.
In the specific embodiment that this is clearly demarcated, the frequency of the situation of described predetermined temperature is greater than to determine following duty with measuring tempeature to current time, and, the number of times occurred is more, corresponding action is more effective for reduction notebook computer temperature, setting like this is based on following consideration:
After execution one-off, if the situation that measuring tempeature is greater than described predetermined temperature still occurs, the operation carried out before showing may be invalid, now need to carry out another action, and this another action is more effective for the temperature reducing notebook computer, as above shown in form, CPU frequency reducing, system hibernates, system depth dormancy and shutdown increase successively for the validity reducing notebook computer temperature.
By the action that this cooling dynamics progressively strengthens, notebook computer can be maintained under predetermined temperature.
Step 105: control described notebook computer and enter described first duty.
Shown in Fig. 2, the detailed process of the inventive method is described.
As shown in Figure 2, after the method starting the embodiment of the present invention, first the value K of counter is set to 0, then enter next step;
Detect the environment temperature in a notebook computer after sense cycle arrives, and judge that whether the detected temperatures T detected is lower than preset temperature T0 (being assumed to 60 degree), if it is returns wait and detects next time, otherwise, enter next step;
The value of counter is added 1, K=K+1;
Judge whether current K equals 1, if so, return wait and detect next time, otherwise enter next step;
Judge whether current K equals K1 (as 2), if so, then return wait and detect next time after application performs CPU frequency reducing action;
Judge whether current K equals K2 (as 4), if so, then return wait after applying for executive system dormancy action and detect next time;
Judge whether current K equals K3 (as 5), if so, then return wait and detect next time after applying for the action of executive system deep-sleep;
Judge whether current K equals K4 (as 8), if so, then terminate after applying for executive system shutdown;
If current K is greater than K4, then likely system fault, re-executes, otherwise shows that K is other values between K1-K4, return wait and detect next time.
Below due to now, the value due to counter is 1, in order to avoid the impact of system sudden change, is 1 do not perform any operation for counter,
For example, assuming that predetermined time interval is 5 minutes, the environment temperature in the time detecting notebook computer namely often spending five minutes, predetermined temperature is 60 degree.The environment in notebook computer is detected at the 5th minute, be assumed to 55 degree, the detection now waiting for the 10th minute, by the 10th minute, assuming that detected temperatures is 65 degree, now due to be first time detect higher than predetermined temperature, K=1, but consider that first time may be system sudden change, now do not make any change, continue to wait for next time.
At the 15th minute, the environment temperature in notebook computer detected, be assumed to 52 degree, K still equals 1, does not now make any change, continues to wait for next time.
At the 20th minute, the environment temperature in notebook computer detected, be assumed to 62 degree, after K adds 1, equal 2, now therefore perform CPU frequency reducing operation.
At the 25th minute, the environment temperature in notebook computer detected, be assumed to 66 degree, after K adds 1, equal 3, because 3 do not have respective operations, detect so continue wait next time;
At the 30th minute, the environment temperature in notebook computer detected, be assumed to 64 degree, equal 4 after K adds 1, the CPU frequency reducing operation before now showing is invalid to reduction temperature, cannot reduce the temperature to less than 60 degree, now, after performing the system hibernates corresponding to number of times 4, wait for and detecting next time.
Certainly, also likely after execution CPU frequency reducing operation, detect environment temperature in notebook always lower than 60 degree, maintain afterwards, certainly likely after executive system deep-sleep, detected temperatures still higher than 60 degree, end of now shutting down.
Above-mentioned all possible process is described in detail no longer one by one.
In above-described embodiment, described frequency is to current time, and the first temperature is greater than the number of times of predetermined temperature, but till described frequency can also being defined as current time, the first temperature is greater than the number of times recurred of predetermined temperature simultaneously.
In other embodiments of the invention, till described frequency is defined as current time, first temperature is greater than the number of times recurred of predetermined temperature, in step 103, when described first judged result represents that described first temperature is not more than described predetermined temperature, described count value is reset.
That is, in step 103 and number of times determining unit, to current time, the frequency that described first temperature is greater than described predetermined temperature is to current time, and described first temperature is greater than the number of times recurred of described predetermined temperature.
Comparatively speaking, till using current time, the first temperature is greater than the number of times recurred of predetermined temperature can more can the time of day of reactive system accurately, illustrates as follows:
Assuming that 20 thermometric judged results are before this as follows: 00000000000000010000 (wherein 1 represent the first temperature be greater than described predetermined temperature, 0 represents that the first temperature is not more than described predetermined temperature), in this case, in measuring at 20 times, only generation temperature is greater than the situation of described predetermined temperature, and return to rapidly afterwards under predetermined temperature, can not adjust for this situation, from overall angle, can think that notebook computer is still under predetermined temperature.And if the first temperature is greater than recurring of described predetermined temperature, then can determine: the temperature of notebook computer cannot be reduced under predetermined temperature by action before, should take the action that cooling dynamics is larger.
In above-described embodiment, if user uses notebook computer, that is, described notebook computer is in using state, now, if carry out the adjustment of duty in the manner described above, likely can cause adverse effect to the operation of the application program that user opens.Such as, the application program of user needs to take more CPU time, but when described frequency reaches 2, carries out frequency reducing to CPU, like this, application program may be caused to run, even cause system in case of system halt.Therefore, in other embodiments of the invention, also detecting notebook computer and whether be in using state, only when being in non-working condition, just performing above-mentioned flow process from step 101.
In general, the screen of notebook computer closes by user, or notebook computer is in (such as, notebook computer encloses in computer package, the latter, and the lamp in room is closed) in dark environment, and representative of consumer does not use notebook computer.Correspondingly, the following two kinds detection mode is provided:

Fig. 3 is the structural representation of the notebook computer of the embodiment of the present invention.With reference to Fig. 3, described notebook computer comprises: temperature detecting unit, the first judging unit, number of times determining unit, duty determining unit and control module.
Temperature detecting unit, for detecting the temperature of described notebook computer within predetermined time interval, obtains the first temperature.Detect the temperature of described notebook computer by arranging temperature-sensing element in notebook computer, such as, can under the keyboard, top, CPU position arranges described temperature-sensing element.The time interval can be arranged as required, such as, arranges every 5 minutes and carries out a temperature sampling.
First judging unit, for judging whether described first temperature is greater than predetermined temperature, produces the first judged result.In BIOS, system protection point is generally 90 degree, and in the present embodiment, preferentially, described in the ratio arranged by described predetermined temperature, system protection point is low, such as, is set to 60 degree.
Number of times determining unit, for when described first judged result represents that described first temperature is greater than described predetermined temperature, till determining current time, described first temperature is greater than the frequency of described predetermined temperature.As long as detect that temperature adjusts different higher than system protection point with regard to carrying out duty immediately from prior art; the embodiment of the present invention utilizes the judged result in multiple time interval to determine the duty of notebook computer; it is more accurate for opportunity to make the adjustment of working with notebook computer state; and; the duty that the combination of different judged result is corresponding different, makes adjustment mode more flexibly effectively.
Exemplarily, described number of times determining unit comprises: count sub-element (not shown), for when described first judged result represents that described first temperature is greater than described predetermined temperature, by representing that described first temperature is greater than the count value increase by 1 of the number of times of described predetermined temperature, obtain described frequency.
Exemplarily, the embodiment of the present invention provides the following two kinds counting mode: (1) is counted by counter, when described first temperature is greater than described predetermined temperature, the count value of described counter is increased by 1, obtains described frequency.(2) counted by a numeric type variable, when described first temperature is greater than described predetermined temperature, the value of this variable is increased by 1, obtains described frequency.

| 4 | System hibernates (S3) |
| 5 | System depth dormancy (S4) |
| 8 | System closedown (S5) |
Control module, enters described first duty for controlling described notebook computer.
As can be seen from above mapping table, when the situation that measuring tempeature is greater than described predetermined temperature only occurs one time, system can not do any process, and only when the situation that measuring tempeature is greater than described predetermined temperature occurs repeatedly, just have corresponding process means (as CPU frequency reducing, system hibernates, system depth dormancy and shutdown etc.).
In the specific embodiment that this is clearly demarcated, be greater than the number of times of the situation of described predetermined temperature with the measuring tempeature occurred before to determine following duty, and, the number of times occurred is more, corresponding action is for reducing the more effective of notebook computer temperature, and so arranging, is based on following consideration:
After execution one-off, if the situation that measuring tempeature is greater than described predetermined temperature still occurs, the operation carried out before showing is invalid, now need to carry out another action, and this another action is more effective for the temperature reducing notebook computer, as above shown in form, CPU frequency reducing, system hibernates, system depth dormancy and shutdown increase successively for the validity reducing notebook computer temperature.
By the action that this cooling dynamics progressively strengthens, notebook computer can be maintained under predetermined temperature.
In other embodiments of the invention, till described frequency can also being defined as current time, first temperature is greater than the number of times recurred of predetermined temperature, therefore, in step 103, when described first judged result represents that described first temperature is not more than described predetermined temperature, described count value is reset.
That is, in step 103 and number of times determining unit, by clear 0 operation of counter, make the count value of counter to be: to current time, described first temperature is greater than the number of times recurred of described predetermined temperature.
Comparatively speaking, till using current time, the first temperature is greater than the number of times recurred of predetermined temperature can more can the time of day of reactive system accurately, illustrates as follows:
Assuming that 20 thermometric judged results are before this as follows: 00000000000000010000 (wherein 1 represent the first temperature be greater than described predetermined temperature, 0 represents that the first temperature is not more than described predetermined temperature), in this case, in measuring at 20 times, only generation temperature is greater than the situation of described predetermined temperature, and return to rapidly afterwards under predetermined temperature, can not adjust for this situation, from overall angle, can think that notebook computer is still under predetermined temperature.And if the first temperature is greater than recurring of described predetermined temperature, then can determine: the temperature of notebook computer cannot be reduced under predetermined temperature by action before, should take the action that cooling dynamics is larger.
Meanwhile, in order to prevent the judged result of previous stage from having an impact to a rear judged result, upper once perform this method time need to counter re-execute once clear 0 operation, illustrate as follows:
