The invention relates to an operation method and a computer system of advanced allocation and a power interface. Wherein, the computer system also comprises a processor and a bus master control device. Power states of the processor in the computer system defined by ACPI are provided with at least a first state (C0 state), a second state (C1 state), a third state (C2 state), a fourth state (C3 state) and a fifth state (C4 state). The method comprises: when time that the bus master control device (Bus Master) sends a request to the processor is before the processor enters into the C3 state, the processor is operated in the C2 state; and when the time that the bus master control device sends a request to the processor is just at the time that the processor enters into the C3 state but doesn't enter into the C4 state, the processor slides over the C4 state and completes the C3 state.
