The specific implementation manner and type of the electronic equipment, the server and the like are not limited in the disclosure.

As shown in fig. 1, the boot apparatus includes:

the state detection module 10 is used for detecting a starting signal of the electronic equipment;

and the control module 20 is electrically connected to the state detection module 10 and configured to set the electronic device to an auto-on mode according to the power-on signal, where the electronic device can be automatically powered on when the electronic device is abnormally powered off and powered on again in the auto-on mode.

By the aid of the device, the electronic equipment can be set to be in the automatic starting mode according to the starting signal of the electronic equipment, when the electronic equipment is abnormally powered down and powered on again, the electronic equipment can be automatically started without manual starting or remote starting of third-party equipment, and accordingly user experience is improved.

The power-on signal may be any form of signal that indicates that the electronic device is in a power-on state. In a possible embodiment, the state detection module 10 may obtain the power-on signal by reading the power-on information recorded by the electronic device, or obtain the power-on signal of the electronic device by other methods, which is not limited in this disclosure.

In a possible embodiment, the power-on signal may include various power-on signals, for example, a power-on signal triggered by a user pressing a power-on key of the electronic device, a power-on signal for remotely controlling the electronic device to power on through a network, and the like, and the disclosure does not limit the type of the power-on signal.

In a possible implementation, the state detection module 10 may be further configured to detect a shutdown signal of the electronic device.

The shutdown signal may be any form of signal that marks the electronic device as entering a shutdown state. For the electronic device, the shutdown mode may include normal shutdown, abnormal shutdown, and the like, for example, when the user performs shutdown through a shutdown key of the electronic device or remotely controls the electronic device to shutdown through other control devices, the shutdown mode of the electronic device belongs to normal shutdown. In addition, the shutdown mode of the electronic device also includes abnormal shutdown, for example, when the electronic device is in a normal operation state, if the power is suddenly cut off (power is cut off by a power grid, power is pulled off, power is cut off by vibration, etc.), the abnormal shutdown of the electronic device may occur. Of course, the above description of the shutdown mode of the electronic device is exemplary and should not be considered as a limitation to the present disclosure, and it should be understood that the normal shutdown and the abnormal shutdown may also include other forms, and the present disclosure is not exhaustive.

In one possible embodiment, the electronic device may record its power-off mode. The different shutdown modes may correspond to different shutdown signals (or referred to as shutdown states), and the shutdown signals may be stored in a storage device (e.g., a hard disk, a ROM, an EEPROM, or the like) of the electronic device, and may be read and identified by the state detection module 10 when necessary, so as to obtain the shutdown mode of the electronic device.

In a possible embodiment, the control module 20 may be further configured to:

In one example, the normal shutdown signal may include a key-press shutdown signal (e.g., via a shutdown key of the electronic device), a remote control shutdown signal (e.g., issued by a third party device), and/or the like.

When the electronic device is normally powered off (the power-off signal is the normal power-off signal), in order to avoid the electronic device being automatically powered on, the embodiment of the disclosure turns off the automatic power-on mode of the electronic device when the normal power-off signal is detected, so as to avoid the electronic device being turned on by mistake, thereby improving user experience.

A possible implementation of the control module 20 is described below.

Referring to fig. 2, fig. 2 is a schematic diagram illustrating a boot device according to an embodiment of the disclosure.

In one possible implementation, as shown in fig. 2, the control module 20 includes a first transistor Q1, a second transistor Q2, a first resistor R1, a third resistor R3, a fourth resistor R4, and a control submodule 210, and the control submodule 210 may include a second resistor R2, where:

a first end of the first resistor R1 and the source S of the first transistor Q1 are electrically connected to the power supply voltage Vbat, a second end of the first resistor R1 is electrically connected to the gate G of the first transistor Q1 and the first end of the second resistor R2, the drain D of the first transistor Q1 is electrically connected to the first end of the third resistor R3,

a second end of the third resistor R3 is electrically connected to the first end of the fourth resistor R4 and the gate G of the second transistor Q2,

the source S of the second transistor Q2, the second terminal of the fourth resistor R4, and the second terminal of the second resistor R2 are grounded, and the output of the drain of the second transistor Q2 is used to control the auto-on mode to be enabled or disabled.

In one possible implementation, the first transistor may be a PMOS transistor and the second transistor may be an NMOS transistor.

Through the device, the automatic starting mode of the electronic equipment can be controlled to take effect or fail by matching of a plurality of elements of the control module.

It should be understood that, although the control module 20 is described with a single resistor (e.g., the first resistor R1, the third resistor R3, etc.) as an example, the disclosure is not limited thereto, and in other possible implementations, a resistor network may be used to replace each resistor provided in the embodiments of the disclosure.

In one possible implementation, the control sub-module 210 may include a Digital programmable Potentiometer (Digital Potentiometer). The digital programmable potentiometer may be connected to the external control component through the IIC interface or the SPI interface, so as to receive the control information or receive the power-on signal, the power-off signal, and the like transmitted by the state detection module 10, and the control submodule 210 may control the digital programmable potentiometer to adjust the resistance value of the second resistor R2 according to the power-on signal and the power-off signal.

In one example, as shown in FIG. 2, the control submodule 210 may be connected to a voltage Vcc, which powers the control submodule 210.

In a possible implementation, the second resistor R2 may be an adjustable resistor, and the control sub-module 210 may be configured to control a resistance value of the second resistor R2 according to a detection result of the state detection module 10. The change of the resistance of the second resistor R2 can change the output signal of the drain of the second transistor Q2, thereby controlling the auto-on mode to be enabled or disabled.

In one example, the second resistor R2 may be a sliding varistor, and preferably, the second resistor R2 may be a programmable sliding varistor.

It should be noted that although the present disclosure describes the digital programmable potentiometer and the sliding rheostat exemplarily, the present disclosure does not limit the specific types of the digital programmable potentiometer and the sliding rheostat, and those skilled in the art can select the appropriate digital programmable potentiometer and sliding rheostat according to the needs.

In one possible implementation, the control sub-module 210 may be configured to:

when the power-on signal is received, the resistance value of the second resistor R2 is adjusted to a first preset resistance value to turn on the first transistor Q1 and the second transistor Q2, and the drain of the second transistor Q2 outputs the first control signal to enable the auto-on mode of the electronic device.

In the embodiment of the present disclosure, the first preset resistance value may be a smaller resistance value, when the resistance value of the second resistor R2 is adjusted to the first preset resistance value, the voltage Vsg (source voltage Vs minus gate voltage Vg) between the source and the gate of the first transistor Q1 is larger (larger than the threshold voltage), so that the first transistor Q1 is turned on, the divided voltage of the power supply voltage Vbat across the fourth resistor R4 reaches the on voltage of the second transistor Q2, the second transistor Q2 is turned on, and the voltage of the drain D of the second transistor is pulled down to a low level (ground), that is, the drain D of the second transistor outputs the first control signal (low level signal) to the PBINT2 pin of the power management chip of the electronic device, thereby enabling the auto-on mode of the electronic device.

In a possible implementation, the control sub-module 210 may further be configured to:

under the condition of receiving the normal shutdown signal, adjusting the resistance value of the second resistor R2 to a second preset resistance value to disconnect the first transistor Q1 and the second transistor Q2, wherein the drain of the second transistor Q2 outputs a second control signal, and the second control signal is used for controlling the automatic power-on mode failure of the electronic device.

The second preset resistance value may be a larger resistance value, when the resistance value of the second resistor R2 is adjusted to the second preset resistance value, the voltage Vsg (source voltage Vs minus gate voltage Vg) between the source and the gate of the first transistor Q1 is smaller (smaller than the threshold voltage), so that the first transistor Q1 is turned off, the divided voltage of the power supply voltage Vbat on the fourth resistor R4 cannot reach the on voltage of the second transistor Q2, the second transistor Q2 is turned off, the voltage of the drain D of the second transistor is pulled high (in a floating state, the specific voltage is determined according to the actual situation), that is, the drain D of the second transistor Q2 outputs a second control signal (high level signal) to the PBINT2 pin of the power management chip of the electronic device, so that the auto-on mode of the electronic device fails.

In one example, the first preset resistance value may be less than the second preset resistance value.

In one example, as shown in fig. 2, the drain D of the second transistor Q2 of the power up device may be electrically connected to the PBINT2 pin of the power management chip of the electronic device to set the voltage at the PBINT2 pin.

It should be noted that in the embodiments of the present disclosure, when PBINT2 pin of the power management chip of the electronic device is pulled low (ground), the electronic device is set to auto-on mode depending on the chip settings and implementation. When the PBINT2 pin of the power management chip of the electronic device is not pulled low to a low level (ground), the auto-on mode of the electronic device fails according to the chip settings and implementation. Of course, in other embodiments, when the auto-on mode of the electronic device is set to the other triggering mode, the resistance of the second resistor R2 may be adaptively changed, so as to adaptively control the auto-on mode of the electronic device to be enabled or disabled.

It should be understood that the above description of the control module is exemplary and should not be construed as limiting the present disclosure, and that modifications or changes to the control module as proposed by the embodiments of the present disclosure may be made by those skilled in the art and are considered to be within the scope of the present disclosure.

The starting device provided by the embodiment of the disclosure is simple and flexible to implement, and can implement effective or invalid setting of the automatic starting mode according to the starting signal and the shutdown signal, thereby improving user experience.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating an auto-on mode of an electronic device according to an embodiment of the disclosure.

As shown in fig. 3, when the electronic device is powered off abnormally, the electronic device is set to the auto-power-on mode by the power-on device, so that the abnormal power-off recovery, that is, the electronic device is powered on automatically. When the electronic equipment is normally started, the state detection module of the starting device can detect a starting signal of the electronic equipment, and the control module of the starting device can set the automatic starting mode to be effective, so that when the electronic equipment is abnormally powered off and is powered on again, the electronic equipment can be automatically started.

As shown in fig. 3, when the electronic device is controlled to be powered off, the state detection module of the power-on device may detect a power-off signal of the electronic device, and when the electronic device is normally powered off (for example, powered off by pressing a key or by remote control), the control module of the control device may set the auto power-on mode of the electronic device to be invalid, so that the electronic device may be normally powered off without being automatically restarted by an error.

Of course, the above description is illustrative, and should not be taken as limiting the disclosure.
