A mainboard state prompting circuit comprises a first switch, a second switch, a third switch, a first light-emitting diode and a second light-emitting diode. A first end of the first switch is connected with a first state signal pin of the mainboard; the second end of the first switch is connected with the cathode of the first light-emitting diode; the anode of the first light-emitting diode is connected with a power supply through a first resistor; the third end of the first switch is grounded; the first end of the second switch is connected with a second state signal pin of the mainboard; the first end of the second switch is connected with the power supply through a second resistor; the second end of the second switch is connected with the cathode of the second light-emitting diode, the anode of the second light-emitting diode is connected with the power supply through the third resistor, the third end of the second switch is connected with the second end of the third switch, the first end of the third switch is connected with the third state signal pin of the mainboard, and the third end of the third switch is grounded. The invention further provides an electronic device. Therefore, the running state of the mainboard can be displayed, and the user can use conveniently.
Description
technical field [0001] The present application relates to a main board state prompt circuit and an electronic device using the main board state prompt circuit. Background technique [0002] According to the Advanced Configuration and Power Management Interface (ACPI) specification, the computer power management system can divide the working state of the computer into S0 to S5, and the meanings they represent are: [0003] S0: The computer works normally, and all hardware designs are turned on or working normally; S1: Also known as POS (Power on Suspend), the CPU stops working, and other hardware devices still work normally; S2: Turn off the CPU, but the rest The hardware device is still running; S3: usually called STR (Suspend to RAM), suspend to memory, write the running data into memory and then turn off the hard disk; S4: also called STD (Suspend to Disk), suspend to RAM Hard disk, memory information is written to the hard disk, and then all components stop working; S5: ...
