In specific implementation process, can be set when the control EC is into before the deep sleep mode, first will with it is described
The level of the pin of the first interface of EC controllers connection is drawn high, i.e., current potential now at the first interface is electricity high
Flat, then the EC controllers enter the deep sleep mode；The processor sent by the first interface first
It is a low level signal to instruct；When the enable trigger signal that the low level signal is the EC controllers, in EC controls
When the current potential of the pin in first interface connection of device is pulled low, the EC controllers are to be waken up, and are operated state.
In specific implementation process, the first interface connects with the universal input/output interface GPIO of the electronic equipment
Connect, by the universal input/output interface GPIO, the described first instruction is sent to the EC controllers.
After the step S103 has been performed, it is possible to perform step S104, i.e.,：The controller is receiving described the
After one instruction, based on the described first instruction, the state of the controller is switched into working condition from the sleep state.
In specific implementation process, when the EC controllers are based on the triggering of the described first instruction, into after working condition,
The EC controllers can initiate the request of the voltage value for battery core described in active inquiry to the power circuit, with again
Confirm the voltage value of the battery core.
In the controller after first instruction is received, based on the described first instruction, by the state of the controller
After switching to working condition from the sleep state, methods described also includes：
The controller is based on the described first instruction, controls the electronic equipment to enter low battery guard mode, wherein, institute
When stating electronic equipment in the low battery guard mode, low battery warning message can be at least issued the user with, and deposit in time
Storage needs the data of storage.
In specific implementation process, the voltage value for confirming the battery core in the EC controllers is less than the default electricity
During value, the electronic equipment can be controlled to enter low battery guard mode, the electronic equipment that protection runs in low battery
Hardware circuit, and the unsaved data of the electronic equipment are preserved in time, low battery alarm is issued the user with, allow users to base
In the alarm of this low battery, in time for the battery core of the electronic equipment provides charging, or preserve what needs were preserved manually in time
The unsaved data, and the electronic equipment is closed in time.
Should indicate herein：In the power module of main flow notebook now, all with a power circuit, the application is profit
The power circuit is used, judges first charge value whether less than a default charge value；In first charge value less than described
During default charge value, send first to the controller by the first interface of the power circuit and instruct, first instruction
For waking up the controller；It can thus be seen that the embodiment of the present application is at the one of existing laptop circuit
In reason device, the method for managing power supply of the application is introduced, actually do not increase other PCB circuits newly or RTC wakes up electricity
Road, so solve cannot wake up and be in deep sleep shape in the case where additionally RTC wake-up circuits are not increased in the prior art
