Embodiment Construction
[0026] refer to figure 2 , which is a block diagram of the first embodiment of the electronic device with power lock function of the present invention. figure 2 Among them, the electronic device 2 with power lock function includes a power switch 21 , a general purpose input / output interface (General Purpose Input / Output, GPIO) 22 , a control unit 23 , a processing module 24 and a logic processing unit 25 .
[0027] When the user presses a touch action on the power switch 21 , the power switch 21 will correspondingly generate a trigger signal 211 . The GPIO 22 is connected to the power switch 21 through a pin (Pin) 221 to receive the trigger signal 211 and transmit the trigger signal 211 to the control unit 23 so that the control unit 23 activates the electronic device 2 with power lock function. Then, the processing module 24 executes instructions such as power-on-self-test (POST) in the logic processing unit 25 to load the operating system to perform the operating system b...

The invention relates to a setting method for power supply locking and an electronic device thereof. The setting method is suitable for the electronic device. The electronic device comprises a power supply switch, a GPIO (General Purpose Input / Output) interface, a control unit, a logic processing unit and a processing module. A power supply control method comprises the following steps of: receiving a trigger signal generated after a power supply switch is pressed down by utilizing a pin of the GPIO interface, transmitting the trigger signal to the control unit, starting the electronic device by using the control unit, and executing power-on self-test of the logic processing unit by the processing unit; judging whether the GPIO interface is set to be in a power supply locking state or not according to the logic processing unit; if the GPIO interface is set to be in the power supply locking state, setting the electric potential of the pin to be a power-forbidden electric potential; and loading an operating system to finish a boot-strap program by utilizing the processing module. According to the process of the power supply control method, the electronic device can not transmit a regenerated trigger signal to the control unit under the working environment of the operating system.
Description
technical field [0001] The invention relates to a method for setting a power lock and an electronic device thereof, in particular to a method for setting a power lock through a baseboard management controller and an electronic device thereof. Background technique [0002] At present, most of the general servers have the lock function of the power button, so as to prevent the non-information management system (Management Information System) personnel from accidentally touching the power button after the server is turned on, so that the server is shut down in an abnormal state, resulting in processing on the server. data cannot be saved, or cause damage to electronic components in the server. [0003] refer to figure 1 , which is a schematic block diagram of a server with a power button locking function in the prior art. figure 1 Among them, the server includes a power button 11, a general purpose input / output interface (General Purpose Input / Output, GPIO) 12, a chipset Sout...
