Embodiment
For above-mentioned and other purposes, feature and advantage of the present invention can be become apparent, cited below particularlyly go out specific embodiments of the invention, and cooperate appended accompanying drawing, be described in detail below.
Please refer to the Organization Chart of Fig. 1 for computer system of the present invention.
Computer system 1 of the present invention can be systems such as desktop PC or notebook computer, but the present invention is not as limit.Computer system 1 comprises power control system 10, power module 30, memory module 40 and chipset 50.Power module 30 is in order to the power supply signal, and whether power supply signal can be transferred to memory module 40 and chipset 50 by power control system 10 with decision.Power module 30 comprises in order to the supply master battery signal, as utilizes external power source and battery supplied, or utilizes the standby power supply signal of reserve battery supply.
Memory module 40 is a CMOS (Complementary Metal Oxide Semiconductor) (Complementary Metal OxideSemiconductor, CMOS), in order to Basic Input or Output System (BIOS) (BasicInput Output System, BIOS) usefulness of execution of storage data so that computer system 1 to be provided.Under general situation, during computer system 1 shutdown, memory module 40 makes its real-time clock (Real Time Clock, RTC) the still sustainable effect of assembly by the standby power supply signal of reserve battery.Can read the correct time when thus, computer system 1 is started shooting.Chipset 50 can be the South Bridge chip of computer system 1, but the present invention is not as limit.Under general situation, during computer system 1 shutdown, master battery signal still can provide chipset 50 a little power supply.Promptly be called system power supply state S5 this moment.
Power control system 10 is in order to the power supply signal of control transmission to memory module 40 and chipset 50.Power control system 10 comprises control module 11, input signal module 12, first on-off circuit 21 and second switch circuit 22.Control module 11 can be embedded controller (Embedded controller) or keyboard controller (Keyboard Controller), but the present invention is not as limit.Input signal module 12 electrically connects with control module 11, in order to input signal to control module 11.The signal that input signal module 12 is imported can be and utilizes Macintosh to continue to push the signal of being keyed in.Thus, can avoid user's false touch.Its Macintosh is to utilize control module 11 to set earlier.For example, can set the user by control module 11 needs elder generation by depressing Fn and C key, simultaneously by depressing power switch key after a period of time, and just can input signal.But the present invention is not exceeded in the above-mentioned mode of pushing.
First on-off circuit 21 electrically connects with control module 11, power module 30 and memory module 40.When 21 conductings of first on-off circuit, can supply memory module 40 power supply signals simultaneously, comprise master battery signal and standby power supply signal.Opening circuit or conducting of control module 11 controls first on-off circuit 21, whether can receive its power supply signal with decision memory module 40.Similarly, second switch circuit 22 electrically connects with control module 11, power module 30 and chipset 50.When 22 conductings of second switch circuit, can supply chipset 50 master battery signals.Opening circuit or conducting of control module 11 control second switch circuit 22, whether can receive master battery signal with decision chipset 50.
Then please refer to the process flow diagram of Fig. 2 about power control method of the present invention.Be noted that herein, though below be the method that example illustrates power supply of the present invention control with computer system 1 with power control system 10, power control method of the present invention is not so that be used in power control system 10 and exceed.
At first carry out step 201: judge whether to import a signal by power control system.
At first power control system 10 judges earlier whether input signal module 12 has input one signal.For example control module 11 utilizes the mode of keyboard scan array to judge whether that Macintosh is pressed, or whether Macintosh has according to particular order and be pressed.
If then carry out step 202: judge whether to continue input and reach one first special time.
Control module 11 judges whether this signal continues input and reach first special time again.For example Macintosh is continued to push above more than eight seconds.First special time can be set by control module 11.
If then carry out step 203.If do not continue to be input to first special time, then might arrive Macintosh, so power control system 10 just can not move for user's false touch.
Step 203: control one first on-off circuit and a second switch circuit, with the signal of cutting off the electricity supply.
Control module 11 is promptly controlled first on-off circuit 21 and second switch circuit 22, and it is opened circuit.Thus, memory module 40 and chipset 50 promptly can't receive power supply signal fully, are included in master battery signal and standby power supply signal under the system power supply state S5.
Carry out step 204 at last: after waiting for one second special time, recover power supply signal again.
Control module 11 through second special time after, for example waited for for three seconds after, control first on-off circuit 21 and second switch circuit 22 again, make its conducting.Promptly restore electricity thus, memory module 40 and chipset 50 can receive master battery signal and standby power supply signal.Via the flow process that above-mentioned step 203 outage and step 204 restore electricity, memory module 40 and chipset 50 can restart.
Be noted that herein power control method of the present invention does not exceed with above-mentioned order of steps, as long as can reach purpose of the present invention, but the also change of above-mentioned order of steps.
Utilize power control system 10 of the present invention and method, can under the hardware structure of not removing computer system 1, memory module 40 and chipset 50 be reset.Especially for for the flow process of standby power supply signal cut, do not need reserve battery is removed.Therefore can save down many workloads, also can avoid damaging the hardware of computer system 1.
To sum up institute is old, and no matter the present invention everywhere all shows it totally different in the feature of known technology with regard to purpose, means and effect, earnestly asks the auditor to perceive, and grants quasi patent early, makes Jiahui society, and the true feeling moral just.Only it should be noted that above-mentioned many embodiment give an example for convenience of explanation, the present invention's interest field required for protection should be as the criterion so that claims scope is described naturally, but not only limits to the foregoing description.
