<p>PROBLEM TO BE SOLVED: To provide a computer system with a further flexible hibernation mode and a method for controlling it. SOLUTION: This system is composed of a host part 1, power source managing part 2, power source part 3 for data backup, power supplying part 4, auxiliary storage device 5, and memory 6. When a batter driving signal is outputted from the power source 3 for data backup due to power failure, the power source managing part 2 outputs an interrupting signal according to a program, the host part 1 backups present data to the auxiliary storage device 5 according to the interruption signal, and outputs a power source interruption instruction word, and the power source managing part 2 interrupts the power supply of this system by outputting a main power source interruption signal according to the power source interruption instruction word, or interrupts the power supply from the system by outputting a battery power source interruption signal. When a wake-up signal is inputted in the power supply interruption state, the power supply is resumed by outputting a power supply signal. When the power failure state is released, and the power supply is resumed, the host part restores a data/working environment, discriminates the wake-up source, and executes an operation according to it.</p> |
