Abstract
The invention is a network controller power-saving device for a computer, where there is a portable computer operating power supply arranged in the computer and the power-saving device comprises: a network controller arranged in the portable computer; a switch arranged between the power supply and the network controller; a control circuit connected with the power supply and the switch; and the network controller comprising a network pin and a power-saving pin, where the network pin is connected with the network controller and the power-saving pin is connected with the control circuit. Thus, as not needing to use the network, separate switching off power supply to the network controller achieves the power-saving efficacy.
Description
Technical field
The network controller electricity saver of the relevant a kind of computer of the present invention particularly about a kind of mode of setting up province's electric pin in the network connector that is used in, reaches the electricity saver of the electric power of network controller in indivedual controlling computer.
Background technology
The use of portable computer is most important just to be that it has the characteristic that is easy to carry and conveniently uses, yet portable computer is not under any circumstance can plug-in to use, so the electricity saver of the serviceable life of battery and portable computer itself is exactly to prolong the portable computer key of service time.
Along with day by day popularizing of world-wide web, the modern also promotes relatively to the degree of dependence of network, when using portable computer, also often need network connectivity, circuit design mode such as Fig. 1 of known portable computer, power supply 30 electrically connects mutually with control circuit 35 and network controller 33 respectively, and network controller 33 and control circuit 35 are electrically to be connected to each other, when the network cable (not shown) is connected with portable computer, network controller 33 is powered to carry out network connectivity work by power supply 30, but when the user need not use world-wide web, though network cable is removed from portable computer, but power supply 30 continued powers are given network controller 33, cause the facts of portable computer power consumption, how when portable computer does not use world-wide web power supply to be stopped power supply to network controller, to reach the purpose of economize on electricity, be the problem that desire of the present invention solves.
Summary of the invention
For overcoming above-mentioned shortcoming, the invention provides a kind of network controller electricity saver of computer, a power supply that provides computer to operate is provided computer, and this electricity saver comprises the network controller of being located in the computer; One control circuit that is connected with this power supply and switch; One is located at the switch between this power supply and this network controller; And a network connector, this network connector comprises a network pin and province's electric pin, and this network pin and this network controller electrically connect, and this province's electric pin and the electric connection of this control circuit.
For above-mentioned and other purposes of the present invention, characteristics and advantage can be become apparent, hereinafter enumerate preferred embodiment especially, and conjunction with figs. is elaborated as follows.
Description of drawings
Fig. 1 is the calcspar of known portable computer electricity saver;
Fig. 2 is the calcspar of the embodiment of the invention;
Fig. 3 meets logic electric potential relation figure between angle and control circuit for power saving of the present invention;
Fig. 4 meets logic electric potential relation figure between angle and control circuit for power saving of the present invention.
Embodiment
See also shown in Figure 2, the network controller electricity saver of computer of the present invention, power supply 10 is located in the portable computer, and electricity saver comprises a switch 11, one control circuit 15, one network connector 12 and a network controller 13, power supply 10 is in order to provide the portable computer required electric power, switch 11 is in order to the power supply of 10 pairs of network controllers 13 of power supply of control portable computer, two ends electrically connect with power supply 10 and network controller 13 respectively, and this switch 11 is the electric-controlled switch of mos field effect transistor (MOSFET), and this control circuit 15 is south bridge controller (SouthbridgeController), and two ends electrically connect with power supply 10 and network connector 12 respectively, again, network connector 12 includes a network pin 121 and province's electric pin 122, the network connector 12 of present embodiment has nine pins, wherein first to the 8th pin is a network pin 121, and in order to the world-wide web line to be provided, and the 9th pin is for economizing electric pin 122.
Please cooperate and consult Fig. 2 and Fig. 3, when user's desire is used world-wide web, at first network cable 20 is connected in the network connector 12 of portable computer (the t1 time of Fig. 3), at this moment, because network cable 20 electrically connects with network connector 12, can form a low logic current potential so economize electric pin 122 and 15 of control circuits, when control circuit 15 receives the signal of this low logic current potential, control circuit 15 is opened switch 11 (turn on), make power supply 10 can supply power to network controller 13, the network pin 121 of network connector 12 then provide network signal 125 to the network controller 13 to carry out the work of world-wide web line, because the connection technology of world-wide web has been a common technique, so do not give unnecessary details.
Please cooperate and consult Fig. 2 and 4, when the user does not use world-wide web, then network cable 20 is removed (the t2 time of Fig. 4), after network cable 20 removes, because network cable 20 does not electrically connect with network connector 12, can form a high logic current potential so economize electric pin 122 and 15 of control circuits, when control circuit 15 receives the signal of this high logic current potential, control circuit 15 cuts out (turnoff) with switch 11, cut off the electricity supply 10 with being connected of network controller 13, so 10 pairs of network controllers 13 of power supply are stopped power supply.
Because the power of portable computer is limited, if will prolong its working time, except lifting battery endurance, more to make the portable computer economize on electricity, by design of the present invention, when the user need not use world-wide web, and with network cable when portable computer removes, power supply 30 is promptly stopped power supply to network controller 33, reaches the effect of portable computer power saving, in addition, the present invention also can be applicable in the general household PC.
Though the present invention discloses as above with preferred embodiment; yet it is not in order to limit the present invention; any person skilled in the art person; without departing from the spirit and scope of the present invention; when the variation that can make all equivalences or replacement, so protection scope of the present invention is when looking accompanying being as the criterion that the application's claim scope defined.
