The network chip is used for detecting the network awakening instruction from the network equipment in real time and sending the detected network awakening instruction to the embedded controller. Specifically, before detecting the wake-on-lan command from the network device in real time, the network chip sets the type of the wake-on-lan command that can be used to wake-on-lan the terminal, so that after detecting the wake-on-lan command, the type of the detected wake-on-lan command is compared with the type of the previously set wake-on-lan command, and when the detected wake-on-lan command is consistent with the type of the previously set wake-on-lan command, the detected wake-on-lan command is determined to be a legal command, and the detected wake-on-lan command is sent to the.
And the embedded controller is used for acquiring a power supply state after receiving the network awakening instruction and carrying out network awakening on the computer according to the system power supply state. Specifically, the embedded controller detects whether the power adapter and the battery are connected to the system through the computer charging control chip, determines that the current power supply state of the terminal is an alternating current power supply state when detecting that the power adapter is connected to the system, and determines that the current power supply state of the terminal is a direct current power supply state when detecting that the battery is connected to the system. And when the system power supply state is determined to be the alternating current power supply state, sending the network awakening instruction to a central processing unit, so as to awaken the computer in the sleep state.
Hereinafter, the computer battery power supply state is referred to as a DC state, the state of receiving AC power by connecting a power adapter is referred to as an AC state, and the sleep state is referred to as an S3 state. From the above, the computer does not support wake-on-LAN under DC S3 and supports wake-on-LAN under AC S3, but does not support wake-on-LAN after unplugging the power adapter.
Furthermore, after the network is awakened, the computer screen can be closed, so that the electric energy of the computer can be saved on one hand, and the display content of the computer screen can be prevented from being peeped on the other hand.
The Wake-on-LAN signal transmitted by the network chip is firstly transmitted to the EC, and the EC determines whether to transmit the Wake-on signal to the MCP according to the current system state, namely the EC controls Wake-on-LAN.
The working flow of the computer network awakening device is as follows:
step 1: the LAN receives a wake-on-LAN command from a network device connected to its portal.
Step 2: the LAN sends the received network control instructions to the EC.
Before the computer goes to sleep, the driver of the LAN will define the type of wake-on-LAN command, and if the previously defined wake-on-LAN command is received by the LAN while sleeping, the LAN will send the wake-on-LAN command to the EC.
And step 3: the EC determines that the system is in an AC state by reading an ACIN signal sent by the charge IC, and determines that the system is in an S3 state by reading SLP _ S3# and SLP _ S4# sent by the MCP, and in this embodiment, when SLP _ S3# is low and SLP _ S4# is high, it is determined whether the computer is in an S3 state.
Where S3 is defined in the advanced configuration and power interface.
Specifically, the charge IC will detect whether the power adapter and battery have been connected to the system, and then the EC will read the charge IC information through the SMBus to know whether AC or DC is supplying power.
And 4, step 4: step4, if EC judges that the system is in AC S3 state, then the received Wake signal is sent to MCP; otherwise, the EC will not forward the received Wake signal.

step S51: under the normal working state of the computer, the drive of the LAN sets the type of the network awakening instruction.
Step S52: the LAN determines whether a wake-on-LAN command from a network device connected to its port is detected, and if so, performs step S53, otherwise repeats the step.
Step S53: the LAN determines whether the detected type of the wake-on-LAN command is consistent with the type set in step S51, and if so, performs step S54, otherwise performs step S55.
Step S54: the LAN transmits the received network awakening instruction to the embedded controller.

step S61: the embedded controller obtains the power supply state and the system state of the computer.
When the charge IC detects that the power adapter is accessed to the system, the information of AC access is transmitted to the EC, namely the power supply state is the AC state;
when the charge IC detects that the battery is accessed to the system, the DC access information is transmitted to the EC, namely the power supply state is the DC state;
when SLP _ S3# of the EC read MCP is low and SLP _ S4# is high, the system state is S3 state.
Step S62: EC judges whether AC S3 is satisfied, if AC S3 state is satisfied, step S63 is executed, otherwise step S64 is executed.
Step S63: the embedded controller sends the network awakening instruction to the central processing unit so as to awaken the computer.
Step S64: and the embedded controller discards the network awakening instruction. .
