ABSTRACT:
A monitoring method and apparatus applied to a computer system having a computer case, a controller and a register for changing the power state of the computer system according to the assembling state of the computer case is disclosed. The method comprises steps of detecting whether the computer case of the computer system is disassembled, generating a trigger signal to the controller when the computer case of the computer system is disassembled, generating a power management signal in response to the trigger signal for changing a system power state indicator of the register, and polling the system power state indicator and driving the computer system into a hibernation mode according to the change of the system power state indicator.
