<p>PROBLEM TO BE SOLVED: To stop a power source against a temperature abnormality inside a device due to an operation abnormality of a cooling fan in the earlier stages, to inform a user of a temperature abnormality not due to the operation abnormality of the cooling fan and to have the cause dissolved. SOLUTION: This information processor is provided with a temperature sensor 1 for checking a temperature inside the device and outputting a temperature monitoring signal S1, a fan sensor 2 for checking the cooling fan and outputting a cooling fan monitoring signal S2, a CPU 3 for reporting a temperature abnormality and a coping method to the user when the temperature monitoring signal S1 is H and the cooling fan monitoring signal S2 is L and turning a power source control signal S4 to H when both of the monitoring signals S1 and S2 are H, a counter 4 for turning the power source control signal S3 to H at the time of counting prescribed time after the input of the cooling fan monitoring signal S2, and a power unit 10 for supplying power to the device and stopping power supply when the power source control signal S3 or S4 becomes H.</p> |
