PROBLEM TO BE SOLVED: To guarantee a function free from error for a computer device even when one processor in mutual monitoring is set in a power saving mode. SOLUTION: In this monitoring method, at least a first processor 1 of two processors 1 and 2 monitors the accurate function of a second processor 2. At this time, the first processor/monitors the outputs signal of the second processor 2 or quantity which is led from the signal on at least the order in time or the content or the signal system. When the first processor 1 is set in an operation mode less in energy consumption different from the second processor 2, it is interrupted that the output signal of the secodn processor 2 is transmitted to the other unit 12.
