Abstract
A method of computer power state management. When an operating system thereof is idle and the processor thereof transits to a clock-suspended power state (C3/C4 state), an arbitrary bit is asserted to prevent requests from being passed through the Northbridge. When the processor is in the C3/C4 state, if a break event is received, the Southbridge transmits the break event to the Northbridge and changes the processor state from C3/C4 to C0 simultaneously. The break event is subsequently transmitted to the processor when the arbitrary bit is disabled.
