In other words, switch 32 is controlled by general input and output pin 3642, when general input and output pin 3642 was in high level state (high state), then switch 32 was cut off, and made systematic electricity feeding unit 35 stop supplies working power Vcc to peripheral element 40.On the contrary, when general input and output pin 3642 was in low level state (low state), then switch 32 was switched on, and made systematic electricity feeding unit 35 can supply working power Vcc to peripheral element 40.
As mentioned above, whether power supply interception driver 37 can detect the application program relevant with peripheral element 40 and be performed.When the application program relevant with peripheral element 40 is not performed, in the present embodiment, power supply interception driver 37 can unloading (unload) driver relevant with peripheral element 40.On the contrary, when the application program that is relevant to peripheral element 40 is performed, 37 of drivers of power supply interception can load the driver of (load) peripheral element 40.
Please refer to Fig. 4, it is depicted as another thin portion synoptic diagram of Fig. 2.
Please refer to Fig. 5, it is depicted as the process flow diagram according to the electricity saving method of a kind of computer system of a preferred embodiment of the present invention.Relevant its explanation is please in the lump with reference to Fig. 3.Electricity saving method is used for above-mentioned computer system 30, and electricity saving method comprises the steps: at first shown in step 510, whether central processing unit 362 is carried out power supplys interception drivers 37, have the application program that is relevant to peripheral element 40 to be performed to detect, and output switch control signal S1 according to this.
When the application program that is relevant to peripheral element 40 is not performed, then shown in step 520, the driver of peripheral element 40 can be tackled driver 37 by power supply unload automatically.
Then shown in step 530, after peripheral element 40 is lost the job power Vcc, peripheral element 40 will enter hot drawing and go out (Hot Plug Out) state.With output switch control signal S1, end, to stop to provide working power Vcc to peripheral element 40 by switch controlling signal S1 gauge tap 32 by 37 planning of power supply interception driver for general input and output pin 3642.
On the contrary, when the application program that is relevant to peripheral element 40 is performed, then shown in step 540, general input and output pin 3642 is planned with output switch control signal S1 by power supply interception driver 37,32 conductings of switch controlling signal S1 gauge tap are to provide working power Vcc to peripheral element 40.
Then shown in step 550, after peripheral element 40 receives working power Vcc, peripheral element 40 will enter heat and insert (Hot Plug In) state.The driver that computer system 30 will be reloaded corresponding peripheral element 40 according to device identification code (Device ID) or manufacturer's identification code (Vendor ID) of peripheral element 40.
Whether whether computer system that the above embodiment of the present invention disclosed and dynamic electricity-saving method thereof have the application program that is relevant to peripheral element to be performed by detecting, provide working power to peripheral element with decision, and then save the battery electric power of computer system.
