PURPOSE: A method and device for stopping and restarting operations of a computer system is provided to remove a rebooting process for restarting an operation of a computer system although an electric power is removed from the computer system by storing statuses of elements of the computer system. CONSTITUTION: While a shutdown request is not received(70), an electric power control logic is remained as an idle status or performs other operation. If a shutdown request is received, the electric power control logic stops a system clock(72). A status is read from system devices including a processor through a scan port in an integrated circuit(73). Statuses of all devices are transmitted to a non-volatile repository(74), a scan clock is stopped, and an electric power is removed from a computer system coder(75). The electric power control logic becomes an idle status until a restarting command is received from a user button, a timer, or other signaling mechanism(76). If a restarting command is received(77), an electric power is recovered to the system devices and the scan clock is reactivated(78). A pre-stored status is read from the non-volatile repository(79), and the status is recorded in the system devices through scan ports(80). The system clocks are recovered(81), and an operation is progressed from the stopped portion thereof. 컴퓨터 시스템 구성요소들의 상태를 저장하기 위한 방법 및 장치는 컴퓨터 시스템 내의 집적회로들의 전력이 완전히 떨어진 이후에 배터리로 작동하는 컴퓨터 시스템들의 재개 동작을 제공한다. 마이크로프로세서 및 다양한 주변 구성요소들로부터 상태가 판독되고 그 상태는 컴퓨터 시스템 동작이 재개될 때까지 비-휘발성 저장소에 저장된다.
