The CPU operates at the highest speed in start processing of an operating system. When a power-saving driver receives a start completion message from the operating system, the power-saving driver waits for a predetermined period until user operation to a computer system is enabled, and then sets the processing speed of the CPU to a user-designated speed. When the power-saving driver receives from the OS an OS termination start message representing the start of shutdown processing, the power-saving driver cancels setting of the user-designated speed, and returns the CPU to, e.g., the highest speed. Hence, start processing/shutdown processing can be executed at a high speed regardless of the set value of the user-designated speed.
