ABSTRACT:
In an information processing apparatus such as a space-saving type personal computer having a liquid-cooling type cooling system, the presence of a cooling liquid, the presence of a frozen state of the cooling liquid and the temperature of the cooling liquid are detected. When a freeze of the cooling liquid is detected, a CPU is throttled down to defrost the cooling liquid, or the cooling liquid is heated to be prevented from being frozen. Alternatively, a warning of detection of a freeze may be displayed. Alternatively, activation of the system may be stopped or operation of the system may be interrupted. By such measures, system failure is prevented from being caused by leaking, shortage, freezing, etc. of the cooling liquid.
