Abstract:
A method of cooling a heat generating portion by circulating a cooling liquid between a heat-absorbing portion and a heat-radiating portion to thereby cool a heat-generating portion including at least a CPU, said heat-absorbing portion being mounted on said heat-generating portion, comprising the steps of:(a) making detection as to whether said cooling liquid is frozen or not; and (b) performing a frozen-state process for said personal computer when a freeze of said cooling liquid is detected, wherein the step (b) includes at least one of the steps of: requesting said CPU to throttle down or to reduce an operating frequency of said CPU to reduce a processing capacity of said CPU to an operable level without circulation of said cooling liquid to thereby defrost said cooling liquid by heat generated in said CPU; indicating a warning of a freeze of said cooling liquid; and stopping the operation of said personal computer.
