Abstract

In a power management method of a computer system, the CPU asserts a clock-suspending grant cycle in response to a clock-suspending signal issued by the south bridge chip, and the south bridge chip issues the clock-suspending signal in response to a data write cycle asserted by the CPU. The clock-suspending grant cycle is to be transmitted to the south bridge chip via the north bridge chip when the CPU is ready to enter a power-saving mode. The north bridge chip performs a first power management operation of the peripheral device in response to the clock-suspending grant cycle. The south bridge chip performs a second power management operation of the computer system in response to the clock-suspending grant cycle.
