All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one
Referring to fig. 1, the present embodiment provides a low power consumption power on/off method, which includes the following steps:
s101, controlling the embedded controller to be powered off when the intelligent terminal is powered off;
s102, when the intelligent terminal is in a power-off state and the embedded controller is powered off, detecting the operation content of a user in real time;

and S104, controlling the intelligent terminal to be started or not to be started after the embedded controller is powered on.
When the intelligent terminal is powered off, the embedded controller is powered off to reduce standby power consumption.
When the intelligent terminal is in a power-off state and the embedded controller is powered off, the embedded controller is triggered to be powered on if the operation content is the operation content of connecting an external power supply, pressing a starting button, connecting external equipment needing charging or opening a cover.
Therefore, after the embedded controller is powered on, the intelligent terminal can be controlled to be powered on or not powered on. It should be understood that the embedded controller is generally provided with a chip, so a program can be set in the chip in advance to determine whether to start up after power-on. Specifically, after the embedded controller is powered on, how to call the program and how to control the intelligent terminal to start up may be implemented by various technical means in the prior art, which is not specifically limited herein.
The low-power-consumption power on and off method provided by the embodiment can reduce power consumption after power off, and can realize power on by connecting an external power supply, pressing a power on key or opening a cover when power on is needed, so that better power on experience is achieved.
Specifically, as an optional implementation manner of this embodiment, after the embedded controller is powered on, the method for controlling the intelligent terminal to be powered on or not powered on specifically includes:
when the intelligent terminal is in a cover closing state, after the embedded controller is triggered to be powered on by opening a cover, the intelligent terminal is controlled to be started or not started; that is, whether the computer is started or not can be set in advance through a program according to actual needs;
when the intelligent terminal is in a cover closing state, after an external device needing charging is connected to trigger the embedded controller to be electrified, the intelligent terminal is controlled not to be started but to provide an external charging function through an interface; the intelligent terminal or the embedded controller provides an external charging function through the interface, so that the charging function is not influenced, and the power consumption can be reduced; specifically, the interface includes, but is not limited to, a USB Type-C interface; the external device to be charged can be a mobile phone, a tablet computer or a flashlight and the like.
When the intelligent terminal is in a cover closing state, after an external power supply is connected to trigger the embedded controller to be electrified, the intelligent terminal is controlled not to be started but to provide an external charging function through an interface; the intelligent terminal or the embedded controller provides an external charging function through the interface, so that the charging function is not influenced, and the power consumption can be reduced;
when the intelligent terminal is in an uncapping state, after a power-on key is pressed to trigger the embedded controller to be powered on, the intelligent terminal is controlled to be powered on; because the intelligent terminal is in the uncapping state, after the startup key is pressed, the embedded controller is directly controlled to start up after being electrified, the operation does not need to press the startup key for a long time, and the startup experience of a user is improved;
when the intelligent terminal is in an uncapped state, an external power supply is connected to trigger the embedded controller to be powered on, and then the intelligent terminal is controlled to be started or not started; that is, whether the computer is started or not can be set in advance through a program according to actual needs.
According to the low-power-consumption power on/off method provided by the embodiment, after the embedded controller is powered on, whether the power on is needed or not is determined according to whether the intelligent terminal is in the cover opening state or the cover closing state, so that the power consumption can be further reduced, and the charging function is not influenced.

Generally, after the power adapter is connected with an external power supply and a power port of the intelligent terminal, the power controller can detect power, so that connection of the external power supply is confirmed, and a first signal can be output. The first signal may be a high level or a low level signal for indicating whether an external power source is connected.

The third signal can be converted into a high level or low level signal to be output, and is used for indicating whether the starting key is pressed or not.
Further, when the external device to be charged is connected to the interface, the interface may output a fourth signal, where the fourth signal may be a high level signal or a low level signal, and is used to indicate whether the external device to be charged is connected.

Furthermore, the power controller, the sensor, the interface and the start-up key are connected with a logic circuit together, and the logic circuit is connected with a load switch of the embedded controller.
Therefore, the first signal, the second signal, the third signal and the fourth signal are transmitted to the logic circuit, and when the logic circuit outputs a trigger edge, the logic circuit triggers the embedded controller to be powered on by triggering the load switch to act. It should be understood that the triggering edge may be a rising edge or a falling edge depending on the setting of the high or low level and the design of the logic circuit. The logic circuit comprises an OR circuit which is used for indicating that any one of four operations of connecting an external power supply, pressing a starting key, connecting an external device needing charging and uncovering can trigger the embedded controller to be electrified.
According to the low-power-consumption startup and shutdown method provided by the embodiment, the operation information of connecting an external power supply, pressing a startup key, connecting external equipment needing charging and uncovering can be sent to the logic circuit, and then whether the embedded controller is powered on or not is controlled through the logic circuit, that is, during standby, the power consumption of the logic circuit replaces the power consumption of the embedded controller, so that the standby power consumption of the intelligent terminal is reduced.
