Embodiment
Refer to Fig. 1, Fig. 2.In order to disclose convenience of the present invention and comprehensible object, in Fig. 1, Fig. 2,20 of computer main frame panels illustrate the nextport hardware component NextPort directly related with the present invention, yet belong to other assembly of computer main frame panel 20 as long as there is no direct correlation with the present invention, omit other assembly is shown.The main function of electronic installation 10 of shutdown power consumption of computer mainboard of the present invention is by power supply unit 30 (Power supply), for example: ATX power supply unit, its permanent standby electricity 30a (stand-byPower) isolates from and for example enters, before computer main frame panel 20: the permanent standby electricity of 5V (or 3V).After computer main frame panel 20 soft-offs (Soft off), electronic installation 10 cuts off a part of electronic component that can consume permanent standby electricity 30a on computer main frame panel 20, only permanent standby electricity is supplied to electronic installation 10 own.When user presses after power switch (Power Button), electronic installation 10 is about to permanent standby electricity 30a conducting and is connected to computer main frame panel 20.
Except permanent standby electricity 30a, other supply electric power of power supply unit 30 is directly connected in the power connector 201 on computer main frame panel 20.
Refer to following comparison sheet 1, relatively active computer motherboard and computer main frame panel of the present invention 20 consume the situation of permanent standby electricity when the S5 of ACPI soft-off (Soft off) state respectively:
Table 1:
From above-mentioned comparison sheet, the computer main frame panel 20 that possesses electronic installation 10 positively can drop to power consumption minimum than active computer motherboard as best one can.
The major function of first device 101 is that the permanent standby electricity 30a (Stand By Power) for controlling power supply unit 30 forms path with computer main frame panel 20 or formation is opened circuit.The concrete element of first device 101 can adopt field effect transistor (MOSFET), the control of the grid (Gate) by 103 pairs of field effect transistors 101 of the second device, can reach and between permanent standby electricity 30a (Stand By Power) to power supply unit 30 and computer main frame panel 20, form the control object that path or formation are opened circuit.
The function of the second device 103 is described below.The concrete main element of implementing the second device 103 at least includes microcontroller 1031.First function of the second device 103 is the power switch signal 105a that produced by power switch 105 for receiving, and for after receiving power switch signal 105a, make first device 101 control permanent standby electricity 30a and computer main frame panel 20 formation paths.Except electronic installation 10 and electronic component relevant to power switch 105, computer main frame panel 20 opens circuit completely with permanent standby electricity 30a under off-mode, therefore, when microcontroller 1031 receives after power switch signal 105a, the grid output conducting control signal 103a of 1031 pairs of field effect transistors 101 of microcontroller, and make field effect transistor 101 conductings, so cause permanent standby electricity 30a and main frame 20 plates to form path, from this moment, all electronic components of main frame 20 can obtain the supply of permanent standby electricity 30a.
Due to, if the 101 moments inflow of the field effect transistor after conducting super-high-current, may make field effect transistor 101 that loads occur excessive and burn, the present invention can set up slow (Soft Start) circuit unit 1033 that starts, and is used for avoiding burning field effect transistor 101 this kind of situation occurs.Soft-start circuit unit 1033 can adopt relevant available circuit means to be achieved.
Moreover in order to improve control voltage, so that can the comparatively cheap field effect transistor 101 of use cost, the present invention can set up charge pump (Charge pump) circuit unit 1035.Charge pump circuit unit 1035 can adopt relevant available circuit means to be achieved.
Second function of the second device 103 is for copying power switch signal 105a, and the power switch signal 105a ' that output copies is to computer main frame panel 20.Obtain the computer main frame panel 20 after permanent standby electricity 30a supply, can produce RSMRST signal (RSMRST signal is for example produced by SIO chip 203), and be transferred to South Bridge chip 205.The second device 103 can be waited for a schedule time, and the length of this schedule time is to depend on for example to wait for, until computer main frame panel 20 has completed the generation RSMRST needed time of signal: the schedule time can be adopted as 100ms.Microcontroller 1031 makes after field effect transistor 101 conductings, wait for (Wait) 100ms schedule time immediately, crossed after 100ms, microcontroller 1031 produces power switch signal 105a ', and power switch signal 105a ' is transferred to SIO chip 203.When SIO chip 203 receives after power switch signal 105a ', the start operation after computer main frame panel 205 is identical with active computer motherboard.
The second device the 3rd function of 103 be for judgement when computer main frame panel 20 is during in the sleep pattern S4 of ACPI state or S5 state, make first device 101 control permanent standby electricity 103a electrical resistances and computer main frame panel 20 formation are opened circuit.
The user of computer main frame panel 20, in windows workspace system, assigns after the shutdown command of shutdown, and in the near future, computer main frame panel 20 can enter sleep pattern S4 state or the S5 state of ACPI.Microcontroller 1031 receives S4 signal or S5 signal condition, makes field effect transistor 101 cut-offs, therefore, causes permanent standby electricity 30a and main frame 20 plates to form and opens circuit.
The second device 103 of the present invention also can adopt Application Specific Integrated Circuit (Application SpecificIntegrated Circuit, ASIC) to give specific embodiment, the truth table of ASIC 103, as described in Table 2:
Table 2:
Above-mentioned SIO chip 203 all can directly be used existing SIO chip and existing South Bridge chip with South Bridge chip 205.
The built-in storage 1031a of microcontroller 1031 can be used as firmware and uses, and built-in storage 1031a can be used to the procedure code that above-mentioned first, second and third function is carried out in storage.Moreover microcontroller 1031 can pass through SM bus (SM Bus) and be connected with South Bridge chip 205, therefore, the renewal of the new firmware of microcontroller 1031 can complete by this SM bus.
The present invention is for reducing the electronic installation of shutdown power consumption of computer mainboard, allow computer main frame panel when the S5 of ACPI soft-off (Soft off) state, it is the same just like the G3 mechanical shutdown that enters ACPI (Mechanical off) to cause computer main frame panel, automatically reach energy-conservationly, this is characterized as advantage of the present invention and greatest feature.
The foregoing is only the preferred embodiments of the present invention, when can not be in order to limit the enforceable scope of the present invention, every those of ordinary skills variation and the modification that obviously can do, all should be considered as not departing from flesh and blood of the present invention.
