When the computer is connected to the socket in the shutdown state, due to the design and working state of the power supply and the mainboard, partial electric energy loss is inevitably generated mainly due to the following points:
1. the power supply itself is lost.
2. The power consumption generated by the wake-up function and the remote control function is realized by the mainboard.
3. The mainboard is powered off to realize special functions, for example, the USB port is charged when the mainboard is powered off to realize that the mobile phone can be charged when the PC is powered off.
From the mainboard end, the 2 nd and 3 rd functions can be controlled to be closed through the BIOS control and the mainboard peripheral circuit, so that the power consumption of the mainboard is close to zero power consumption. However, when viewed from the power supply terminal of the desktop PC, since the power supply needs to output 5Vsb after receiving the AC voltage, part of the AC-DC circuit is in an operating state. The energy consumption of the part can be between 0.1 and 0.2W at the lowest level in the industry.
At present, a solution for power consumption generated when a computer is shut down is to integrate a storage battery, however, when the electric quantity of the storage battery is lower than a certain value, a charging circuit is in a working state to charge the storage battery, the power consumption at the moment is larger than the power consumption generated when the computer is in a standby state, and the electric energy is not actually saved.

the alternating current-to-direct current module is used for converting alternating current passing through the third switch into direct current voltage, setting a control point of the second switch to be a high level and locking the second switch in a closed state;
and the SIO is used for controlling the second voltage control source to continuously lower the control point of the third switch when the power switch is closed so as to normally close the third power supply, so that the computer is switched from a shutdown state to a soft shutdown state.
Specifically, the voltage control unit is a dc controlled circuit, and the ac conversion module is a circuit for converting an ac signal into a dc signal.
In an embodiment of the present invention, the SIO is configured to detect whether a remote control or a network wakeup setting of the computer in a soft shutdown state is started in the BIOS when the shutdown signal is received, and if so, control the second voltage control source to provide a continuous low level to a control point of the third switch to enable the third switch to be in a closed state, so that the computer enters the soft shutdown state.
In an embodiment of the present invention, the apparatus further includes a capacitor C3 and a resistor R3; fig. 2 is a circuit diagram of the zero power consumption standby control of the computer. The SIO is connected with the BIOS, one end of the power supply, one end of the first switch K1, one end of the first Voltage control source1 and one end of the second Voltage control source 2; the other end of the Voltage control source1 is connected with a control point K1control point of the first switch K1; the other end of the first switch K1 is connected with a switching POWER supply and is grounded; the PSU is connected with one end of the second switch K2 and one end of the capacitor C3; the other end of the second switch K2 is connected with the other end of the capacitor C3; one end of the third switch K3 is connected with the other end of the resistor R3, and the other end of the third switch K3 is connected with one end of the AC-to-DC module; the other end of the AC-to-DC module is connected with a control point K2 control point of the second switch K2; the other end of the second Voltage control source 2 is connected with a control point K3control point of the third switch K3; the first Voltage control source1 and the second Voltage control source 2 are both connected with a 5V power supply.
In an embodiment of the present invention, when the computer enters the soft-off state from the off state, the SIO is configured to control the first voltage control source to supply a high control point voltage to the first switch, and turn off the first switch to keep the computer in the on state.
Specifically, the states of a computer are generally divided into 3 types:
g3: the computer is in a state of complete shutdown, namely the state of the computer when the AC input end of the computer is cut off.
S5: the computer is in a soft-off state, in which all components of the computer are in an off state and only the SIO is in a standby state. In this state, the 5Vsb of the computer system is also present. 5Vsb is the 5V supply for the system standby use.
S0: the computer is in a starting state. For a user, the state of the computer when mainboard information and Logo appear after the computer is started.
The K1 and K3 switches are normally closed controllable switches, K1(K3) is open when the voltage of K1(K3) control point (i.e. the control point described above) is high (low), otherwise K1(K3) is closed; k2 is a normally open controllable switch, K2 is closed at K2 control point high, otherwise it is open.
Starting a computer: when the user plugs in the AC power supply, the machine power supply is not working with electricity because K2 is a normally open switch. The computer is in the G3 state. When a user presses a power switch (yellow frame part), K2 is closed, alternating current becomes direct current voltage after passing through K3 and an alternating current-direct current module, so that K2 control point is at high level, and K2 is locked in a closed state. In addition, SIO controls the second voltage control source to give K3control point a low hold level so that K3 is always in the off state. At this time, the computer enters the S5 state from G3. Since K1 is a normally closed switch, the SIO will get a low level power-on signal of the power switch after the computer enters S5, and when the computer enters S0 from S5, the SIO controls the first voltage control source to make K1control point high level, and K1 is open, so as to avoid that the computer enters a shutdown process because K1 is closed for a long time. Thus, the computer completes the boot process from G3 to S0.
The computer is shut down or enters dormancy: when a user turns off the computer under the OS or presses a power key, after the system obtains a power-off signal, the SIO needs to detect function settings which need to be realized under S5, such as network wakeup and remote control under power-off in the BIOS, and if the user starts the settings, after the computer enters S5, the SIO keeps the K3control point at a high level all the time, so that the computer is in the S5 state all the time. If the user has turned off the function settings that need to be implemented in S5, such as web wakeup under BIOS and remote control under shutdown, the SIO will make K3control point high, let K3 turn off, so that K2 control point becomes low, and K2 turns off. Therefore, the alternating current is cut off after the computer is shut down, and the power consumption of the whole computer is enabled to be zero.
In an embodiment of the present invention, as shown in fig. 3, the ac-to-dc conversion module includes: the diode D1, the resistor R4, the capacitor C2 and the resistor R5;
the anode of the diode D1 is connected with the other end of the third switch K3, and the cathode of the diode D2 is connected with one end of the resistor R4 and the anode of the capacitor C2; the negative electrode of the capacitor C2 is connected with one end of the resistor R5 and is grounded; the other end of the resistor R5 is connected with the other end of the resistor R4 and a control point K2CP of the second switch K2.
As shown in fig. 4, an embodiment of the present invention provides a computer zero power consumption standby control method based on the computer zero power consumption standby control apparatus in fig. 1, where the method includes the following steps:
step 401: when a user shuts down the computer under a system OS or presses a power key, the SIO receives a shutdown signal and detects whether remote control or network awakening setting of the computer under a soft shutdown state is started in the BIOS, wherein the soft shutdown state is used for representing the running state that all components except the SIO are in a shutdown state;
step 402: if the remote control or the wake-on-LAN setting is not started in the BIOS, switching the control point of the third switch to a high level state and disconnecting the control point of the third switch so as to change the control point of the second switch to a low level state;
step 403: the second switch is disconnected when the control point of the second switch is in a low level state;
step 404: and the power supply PSU is used for cutting off alternating current when the second switch is disconnected so as to enable the computer to enter a complete shutdown state and be in a zero power consumption state.
In an embodiment of the present invention, the second switch is closed when a user presses the power switch, so that the ac power passes through the third switch to the ac-to-dc module;
the alternating current-to-direct current module converts alternating current passing through the third switch into direct current voltage, a control point of the second switch is a high level, and the second switch is locked in a closed state;
the SIO controls the second voltage control source to the third switch when the power switch is closed
And the control point keeps low level to make the third power supply normally closed so as to switch the computer from the power-off state to the soft power-off state.
In an embodiment of the present invention, when receiving the shutdown signal, the SIO detects whether a remote control or a wake-on-lan setting of the computer in a soft shutdown state is started in the BIOS, and if so, controls the second voltage control source to provide a continuous low level to a control point of the third switch to make the third switch in a closed state, so that the computer enters the soft shutdown state.

the anode of the diode D1 is connected with the other end of the third switch K3, and the cathode of the diode D2 is connected with one end of the resistor R4 and the anode of the capacitor C2; the negative electrode of the capacitor C2 is connected with one end of the resistor R5 and is grounded; the other end of the resistor R5 is connected with the other end of the resistor R4 and a control point K2CP of the second switch K2.
6. The apparatus of claim 5,
when the computer enters a soft shutdown state from a shutdown state, the SIO is used for controlling the first voltage control source to supply a high level to the control point of the first switch, and disconnecting the first switch to keep the computer in the startup state.
7. The computer zero power consumption standby control method based on the computer zero power consumption standby control device of any one of claims 1-6, characterized by comprising the following steps:
when a user shuts down the computer under a system OS or presses a power key, the SIO receives a shutdown signal and detects whether remote control or network awakening setting of the computer under a soft shutdown state is started in the BIOS, wherein the soft shutdown state is used for representing the running state that all components except the SIO are in a shutdown state;
if the remote control or the wake-on-LAN setting is not started in the BIOS, switching the control point of the third switch to a high level state and disconnecting the control point of the third switch so as to change the control point of the second switch to a low level state;
the second switch is disconnected when the control point of the second switch is in a low level state;
and the power supply PSU is used for cutting off alternating current when the second switch is disconnected so as to enable the computer to enter a complete shutdown state and be in a zero power consumption state.
8. The method of claim 7,
the second switch is closed when a user presses the power switch so that the alternating current passes through the third switch to the alternating current-to-direct current module;
the alternating current-to-direct current module converts alternating current passing through the third switch into direct current voltage, a control point of the second switch is a high level, and the second switch is locked in a closed state;
and the SIO controls the second voltage control source to continuously lower the control point of the third switch when the power switch is closed so as to normally close the third power supply, so that the computer is switched from a shutdown state to a soft shutdown state.
9. The method of claim 8,
and when the SIO receives the shutdown signal, detecting whether remote control or network awakening setting of the computer in a soft shutdown state is started in the BIOS, and if so, controlling the second voltage control source to provide a continuous low level for a control point of the third switch so as to enable the third switch to be in a closed state, so that the computer enters the soft shutdown state.
10. A zero power consumption standby control system of a computer, comprising the zero power consumption standby control device of any one of claims 6 to 9 and the computer.
