Abstract: A circuit allowing self-recovery of an operating system (OS) includes a PCH chip, a switch chip, a first ROM, a second ROM, a connector, and a storage unit. The switch chip, the second ROM, and the connector are coupled to the PCH chip. The first ROM is coupled to the PCH chip through the switch chip. The second ROM controls the PCH chip to output a signal according to the state of the operating system. The first ROM stores a backup the operating system. The switch chip receives control signal from the PCH chip, and controls whether the first ROM communicates with the PCH chip, to allow recovery of the entire or part of the OS in the event that repair is required.

Abstract: An electronic device includes a motherboard and a display. The motherboard includes a south bridge chip, a leak-proof circuit, and a connector. The leak-proof circuit includes a control unit and a first signal transmission unit. The control unit is electrically coupled to a power supply. The first signal transmission unit includes a first electronic switch, a second electronic switch and a first resistor. The second electronic switch is electrically coupled to ground through the first resistor. When the motherboard is turned off and the display is turned on, the power supply does not provide power to the control unit, and the control unit outputs a first control signal to the first and the second electronic switches. The first and the second electronic switches are in pinch-off mode. Signals from the display flow into ground through the second electronic switch and the first resistor.
