For example, after detecting the boot instruction, the processor 102 loads the preset information in the first memory 100 to the second memory 101 for the processor 102 to boot the electronic device 10.
In one embodiment, the second memory 101 is also used for temporarily storing data exchanged with an external memory of the electronic device 10, operation data of the processor 102, and the like.
In one embodiment, the first memory and the second memory may be different types of memory.

In one embodiment, the first power supply component 103 comprises a battery pack having a battery capacity that is less than a battery capacity of a battery pack of the second power supply component 104.
It will be appreciated that, given a battery capacity per unit volume determination, the greater the battery capacity of the power pack, the greater the volume and, correspondingly, the greater the battery capacity of the first power supply assembly, the greater its volume. Therefore, considering that the second power supply assembly 104 is used for supplying power to the second memory device 101 and the processor 102, and the first power supply assembly 103 is used for supplying power to the first memory device 100, the power requirement of the first power supply assembly 103 is much smaller than the power requirement of the second power supply assembly 104, and therefore, the battery capacity of the battery pack contained in the first power supply assembly 103 is considered to be smaller than the battery capacity of the battery pack of the second power supply assembly 104.
Meanwhile, based on the light and thin design requirement of the electronic device, the hardware cost consideration, and the practical application requirement of the electronic device, the battery capacity of the battery pack of the first power supply module 103 may be reduced as much as possible on the basis that the first power supply module 103 basically meets the power supply requirement of the first memory 100.

Here, the charging connection of the first power supply component 103 is connected to the system power supply connection of the second power supply component 104 to obtain power, and there is no need to plan an external charging interface for the first power supply component 103 to obtain power from an external power supply, reducing the impact on the external interface planning and appearance of the electronic device.
In one embodiment, the first power supply module 103 is connected to at least one charging interface exposed outside the electronic device, and the first power supply module 103 is connected to an external power source through the charging interface for charging, so that the first power supply module 103 can directly supplement electric energy through the external power source regardless of whether the electronic device 10 is turned on, thereby ensuring that the first memory device 100 is continuously powered on, and data stored in the first memory device 100 is not cleared.
In this embodiment, when the second power supply assembly 104 supplies power normally, the first controlled switch is used to electrically connect the first memory 100 and the second power supply assembly 104, so that the second power supply assembly 104 supplies power to the first memory 100.
In one embodiment, the first controlled switch is used to make or break an electrical connection between the first memory 100 and the second power supply component 104. When the second power supply module 104 supplies power normally, the first controlled switch is turned on, and the second power supply module 104 supplies power to the first memory 100; when the second power supply unit 104 stops supplying power, the first controlled switch is turned off, and the first power supply unit 103 supplies power to the first memory 100.

step S104: loading the preset information cached by the first memory device to the second memory device;
step S105: and starting the electronic equipment based on the content loaded by the second memory.
In this embodiment, the electronic device detects a start instruction. For example, the power management module of the electronic device detects whether the second power supply component is turned on, and if the second power supply component is detected to be turned on, it is considered that the start instruction is detected. And if the starting instruction is detected, the power management module controls the second power supply assembly to recover power supply to the processor and the second memory.

Here, before the preset information cached in the first memory is loaded into the second memory, it is first determined whether the preset information is cached in the first memory to identify information loss caused by a failure or power failure of the first memory, and if the preset information is not cached in the first memory, information required for starting the electronic device is loaded from a hard disk of the electronic device, and the information required for starting the electronic device is stored in the first memory to ensure that the information required for starting the electronic device is successfully loaded into the second memory.
In one embodiment, as shown in fig. 3, the method further comprises:
step S102: and after the second power supply component resumes supplying power, turning on the electrical connection between the first power supply component and the second power supply component, and after the electrical connection between the first power supply component and the second power supply component is turned on, supplying power to the first power supply component by the second power supply component.
Specifically, as shown in fig. 4, the first power supply component and the second power supply component are connected by a second controlled switch, and the first power supply component and the second power supply component can be controlled to be turned on or off by the second controlled switch.

For example, the power management module of the electronic device detects whether the second power supply component is disconnected, and if the power supply is disconnected, it is considered that the shutdown instruction is detected. And after detecting a closing instruction, writing information required by the next starting of the electronic equipment into the first memory as the preset information.
In an embodiment, after the information required for starting the electronic device is written in the first memory, the information in the first memory is always stored when the first memory is not powered off, so that before the information required for starting the electronic device next time is used as the preset information and written in the first memory, it is further determined whether the information required for starting the electronic device has been written in the first memory: if it is determined that information required for starting the electronic equipment does not exist in the first memory, writing the information required for starting the electronic equipment into the first memory as the preset information; if it is determined that the information required for starting the electronic device exists in the first memory, the process directly proceeds to step S108.
In this embodiment, please refer to fig. 4 again, after the preset information is successfully written into the first memory or it is determined that information required for starting the electronic device exists in the first memory, the first power supply assembly is electrically connected to the first memory through a third controlled switch; after the electrical connection between the first power supply component and the first memory is turned on, the second controlled switch disconnects the electrical connection between the second power supply component and the first power supply component, and/or the first controlled switch disconnects the electrical connection between the second power supply component and the first memory. Here, by disconnecting the electrical connection between the second power supply component and the first power supply component and/or the first memory device, the second power supply component no longer supplies power to the first power supply component and/or the first memory device, and by conducting the electrical connection between the first power supply component and the first memory device, the first power supply component continues to supply power to the first memory device to prevent information in the first memory device from being purged.
In this embodiment, after the first power supply assembly is electrically connected to the first memory, and the second power supply assembly is disconnected from the first power supply assembly and/or the first memory, respectively, the power management module stops supplying power to the second power supply assembly electrically connected to the first power supply assembly and/or the second memory, so as to shut down the electronic device.
