Abstract:
A computer monitoring device, comprising:starting circuit which outputs a starting signal before starting a computer, said starting circuit outputting a starting signal to the computer when a clock signal, which is output from the started computer in a predetermined cycle, is stopped for a predetermined period of time; start stopping circuit which stops an operation of said starting circuit when a standby signal, which is output from the computer with a predetermined timing, is input; start operation determination circuit which outputs a third signal in response to inputting of the starting signal, which urges stopping of an operation of said start stopping circuit, said start operation determination circuit stopping outputting of the third signal by detecting the clock signal which is output from the computer only when the standby signal is not detected; and operation monitoring circuit which stops outputting of the input standby signal to said start stopping circuit when said start operation determination circuit outputs the third signal.
