| 1. A monitoring method for use in a computer system having a computer case, a controller and a register for changing a power
state of said computer system according to the assembling state of said computer case, said method comprising:
detecting whether said computer case of said computer system is disassembled with a detecting component disposed on an outside
surface of said computer case;
generating a trigger signal to said controller and detecting whether said computer system is in a normal operating mode power
state when said computer case of said computer system is disassembled;
transforming said computer system into said normal operating mode power state when it is detected that said computer system
is not in said normal operating mode power state and said computer case of said computer system is disassembled;
generating a power management signal in response to said trigger signal for changing a system power state indicator of said
register; and
polling said system power state indicator and driving said computer system from said normal operating mode power state into
a hibernation mode according to the change of said system power state indicator,
wherein the detecting component has a roll structure leaning against a cover of said computer case for mechanically detecting
whether said computer case is disassembled.
