Abstract

An information processing apparatus includes a fan sensor for detecting a failure of a fan for cooling an inside of the apparatus and for outputting a cooling fan failure signal, a counter for starting time counting when the cooling fan failure signal is output and for outputting a time-out signal when counting to a predetermined value, and a power supply unit for supplying a power to the information processing apparatus and for stopping the power supply responding to the time-out signal, so as to prevent electronic components from being damaged by heat. If a cooling fan failure signal is output, the apparatus notifies a user of the fan failure and of a stop warning and performs a software protective operation during time counting with the counter. The apparatus further includes a temperature sensor for checking the temperature in the apparatus and for outputting a temperature monitor signal, it notifies a user of an abnormal temperature and of how to cope with it if the temperature monitor signal is H and a cooling fan monitor signal is L and stops the power supply if both of the monitor signals are H, by which a user can be notified of the abnormal temperature independently of an abnormal operation of the cooling fan so as to remove the cause of the abnormality.
