Abstract
The present invention relates to a method for controlling an operation mode of a computer system, which comprises the following steps: detecting time of the computer system is supplied with power by second power source when the computer system is supplied with power by first power source converting into by second power source; changing the operation mode of the computer system if the time of supplying power to the computer system by the second source the computer system is less than a preset time interval, otherwise, the operation mode of the computer system is not changed.
Description
(1) technical field
The present invention provides the method for the operator scheme of a kind of controlling computer system, refers to a kind of method that whether changes the operator scheme of this computer system by the power-on time of the power supply of judging this computer system electric power of supply with decision especially.
(2) background technology
General computer system can be installed an AC/DC converter (AC/DC adapter), is used to provide electric power and gives the interior every electronic component use of computer system.Excessive and damaged for fear of consumption power of computer system, have the design of overload protection usually in the AC/DC converter.Yet, along with computer system system clock pulse constantly soaring (amplitude of frequency of operation progress that especially accounts for the exhausted most central processing unit of whole computer system power consumption is surprising especially), the required power consumption of computer system also relatively promotes, in general, the central processing unit maximum consumption power of existing computer system is between 60W to 90W, the then about 16W of other peripheral devices, so the power that whole computer system consumed is approximately between the 76W to 106W, and the specification of the AC/DC converter that present computer system is on the market used always has 90W and 120W.
Yet the use habit of most computer system is to be used for being the copy editor mostly, or DVD playing back, VCD or the like, these the time can't allow central processing unit remain on the highest frequency running in fact always and too many power consumption is arranged.If select the AC/DC converter of 120W for use, though can take the central processing unit of highest frequency into account normally operates, but in such event, because central processing unit can't remain on the highest frequency running always, so just have the power dissipation of extra 14W to 44W.And the volume of AC/DC converter becomes positively related relation with its peak power that can provide usually; also can provide its volume of more powerful AC/DC converter usually can be bigger; therefore if select more powerful AC/DC converter for use, its bigger volume will bring the puzzlement that user's inconvenience is carried.
So in the time of most of, use the AC/DC converter of 90W just to be enough to deal with the environment for use that aforementioned consumable power is about the major part of the computer system between the 76W to 106W, but this still can run into emergency situations.Please refer to Fig. 1, Fig. 1 is used for representing computer system in the moment of each time point consumed power for the sequential chart of existing consumption power of computer system, abscissa express time wherein, and ordinate is represented the computer system system consumption power of moment.Suppose earlier that at this peak power that AC/DC converter in computer system can provide is P
MAXBe 90W.Though in the ordinary course of things, the moment system consumption power of computer system can be lower than P usually
MAXYet when the user carries out some huge program or same time when carrying out too many program, the moment system consumption power of computer system promptly probably can exceed the peak power P that AC/DC converter can provide
MAX, and make computer system present unstable state, or cause the overload protection of AC/DC converter to be activated and computer system is closed because of the power supply supply is cut off.For example among Fig. 1 time point T1 to the situation during this period of time of time point T2, during this in the moment system consumption power of computer system surpassed AC/DC converter institute can safety and the stable peak power P that operates
MAXTherefore; when computer system makes its consumed power increase in the minority time because central processing unit must carry out more program; tend to make computer system maximum possible consumed power is thus lifted to can provide peak power greater than its original AC/DC converter degree; for fear of make AC/DC converter give the computer system use because of consumed power is excessive because of its overload protection design stops supply electric power; and cause computer system not closed with having early warning; so some computer system inside can be provided with a battery; give computer system with temporary transient power supply, until AC/DC converter recovers till the computer system power supply.
(3) summary of the invention
Therefore, the purpose of this invention is to provide a kind ofly whether change the method for operator scheme of this computer system with decision, to solve the above problems by the power-on time of judging this computer system of battery supplied.
According to the method for the operator scheme of a kind of controlling computer provided by the invention system, it comprises the following step: when this computer system transfers to by a powered battery by an AC/DC converter, detect this computer system by this battery powered time; And if this computer system, was then reduced the computer system frequency of operation, otherwise is not reduced the computer system frequency of operation during less than a scheduled time slot by this battery powered time.
Wherein this computer system is a notebook computer.In addition, in step (b), if this computer system during less than a scheduled time slot, then can reduce the computing frequency of central processing unit, electronic installation or the bus of this computer system, to reduce the power consumption of this computer system by this battery powered time.

(5) embodiment
Please refer to Fig. 2, Fig. 2 is the functional block diagram of the computer system 10 of one embodiment of the invention.Computer system 10 can be a notebook computer, computer system 10 comprises a battery 16, a voltage divider 18, a ROM-BIOS (Basic Input Output System, BIOS) 22, one central processing unit (CPU) 20, an output/input interface 26, a hard disk drive 28 and a bus 24.Wherein, the required electric power of computer system 10 runnings can be provided by a battery 16 or an external AC/DC converter (AC/DC adapter) 14, and AC/DC converter 14 be electrically connected on an AC power 50 (as electric main), be used for the alternating voltage that AC power 50 is provided is converted to a stable DC voltage of exporting, and provide DC voltage to use to computer system 10.Voltage divider 18 is to be electrically connected on AC/DC converter 14, it mainly is that the DC voltage that is used for that AC/DC converter 14 is exported converts a plurality of magnitudes of voltage DC voltage DC1 inequality, DC2 etc. to, to be supplied to the different electronic components of different DC voltage demands in the computer system 10 respectively.Central processing unit 20 is to be used for handling procedure and data, ROM-BIOS 22 is the boot programs that are used for carrying out computer system 10, output/input interface 26 can be a drawing interface, a network interface or an audio interface, and it is by the mutual Data transmission of bus 24 and other peripheral devices (as hard disk drive 28).
See also Fig. 3, Fig. 3 is the process flow diagram of operator scheme of the controlling computer system 10 of one embodiment of the invention, and its step is as follows:
Step 100: computer system 10 is by AC/DC converter 14 supply electric power;
Step 102: when computer system transferred to by battery 16 power supplies by AC/DC converter 14, whether less than a scheduled time slot, if then execution in step 104, if not, then execution in step 106 by battery 16 supplying time for detection computer system 10;
Step 104: the operator scheme that changes computer system 10;
Step 106: the operator scheme that does not change computer system 10.
Please in the lump with reference to figure 3 and Fig. 4, Fig. 4 is the sequential chart of the alternating-current detection signal of one embodiment of the invention.Under the general work pattern, AC/DC converter 14 can give computer system 10 by the supply electric power, and the alternating-current detection signal AC_IN# that sends a logic " 1 " gives ROM-BIOS 22 (step 100).Yet; in case increasing suddenly and surpass going up of AC/DC converter 14, the load of computer system 10 prescribes a time limit; the load protection of AC/DC converter 14 can make AC/DC converter 14 temporary transient stop supplies electric power give computer system 10; can keep electric power supply in case data run off this moment by battery 16; ROM-BIOS 22 then can receive the alternating-current detection signal AC_IN# of a logic " 0 ", and expression AC/DC converter this moment 14 not power supply gives computer system 10.In case AC/DC converter 14 restores electricity again when giving computer system 10 once again, meaning is the alternating-current detection signal AC_IN# that ROM-BIOS 22 can receive a logic " 1 " once more, whether ROM-BIOS 22 meetings this moment relatively alternating-current detection signal AC_IN# maintain the time of logic " 0 " less than a scheduled time slot (step 102), general predeterminable this scheduled time slot is about 25 milliseconds (msec), this is because after generally computer system 10 switches to battery 16 power supplies from AC/DC converter 14, need 10 ~ 20 milliseconds approximately by battery 16 supplying time.If computer system 10 is by battery 16 supplying time during less than this scheduled time slot, mean that then computer system makes load voltage surpass the maximal value that AC/DC converter 14 can bear because there is a large amount of needs of work to carry out 10 this moments really, at this moment 10 of computer systems can be when being returned to by AC/DC converter 14 supply electric power, reduce the computing frequency of central processing unit 20, or reduce the frequency of operation of electronic installation (as hard disk drive 28 or output/input interface 26 etc.) in the computer system 10 or reduce the clock pulse of the bus 24 of computer system 10, reducing the power consumption of whole computer system 10, thereby prevent that computer system 10 from damaging (step 104) because of exceeding power termination.If computer system 10 is by battery 16 supplying time during more than or equal to this scheduled time slot, this expression AC/DC converter 14 has the long period do not power (step 106), in other words, battery 16 has long power-on time, this is because the user does not use AC/DC converter 14 to supply computer system 10 for some reason, for instance, the user just hopes the position of adjusting computer system 10, may be from the meeting room of changing to the next door of original meeting room, so electric power supply of necessary temporarily disconnected AC/DC converter 14, rather than because the too big institute of the load of AC/DC converter 14 causes the power supply stop supplies, after so in case the user reuses AC/DC converter 14 supply electric power, meaning is the alternating-current detection signal AC_IN# that ROM-BIOS 22 can receive a logic " 1 " once more, the alternating-current detection signal AC_IN# that this moment, ROM-BIOS 22 can be judged logic " 0 " keeps above 20 milliseconds, all are normal will to know AC/DC converter 14 power supplies, need not reduce the computing frequency of central processing unit 20, or reduce the frequency of operation of electronic installation (as hard disk drive 28 or output/input interface 26 etc.) in the computer system 10 or reduce the clock pulse of the bus 24 of computer system 10.
Compared to prior art, the method of the operator scheme of controlling computer of the present invention system can be in computer system by power conversions that AC/DC converter provided during by battery supplied electric power, by the time of judging battery supplied electric power, with the decision computer system whether because take place can't load system maximum instantaneous consumed power situation, and the frequency of operation that need in time reduce computer system is to reduce the moment total consumed power, or the moment consumed power of computer system still meets the peak power that AC/DC converter can provide, and just needs the power supply supply of temporarily disconnected AC/DC converter for some reason and does not need unnecessary frequency reducing action.Utilize this mode can on computer system, use the AC/DC converter of smaller power, only need under a few cases, to reduce the frequency of operation of computer system, not only can reduce power dissipation and also can suitably adjust the frequency of operation of computer system, and computer system need not buy more high-power AC/DC converter for the work requirements that satisfies the central processing unit highest frequency in addition yet, and this can reduce many extra costs expenditures.
The above only is preferred embodiment of the present invention, and all equivalences of having done according to the present patent application claim change with equivalence replaces, and all should belong to the covering scope of patent of the present invention.
