ABSTRACT:
An assembly includes a circuit board (20) with a component attached thereon, a power supply (10) for providing power to the circuit board and the component separately, an ACPI chipset (65) for controlling the power supply, a protecting circuit (61) connected to the component, an I/O controller (64), and an enable circuit (62) for activating the I/O controller. The protecting circuit generates a protecting signal while the component is not connected properly to its power source. The I/O controller is responsive to the protecting signal to send a control signal to the ACPI chipset for shutting off the power supply.
