Abstract:
An electronic device comprising:a calculation processing unit that calculation-processes software information that is input; a power source unit that supplies electric power to said calculation processing unit; a temperature detection means that detects the temperature of said calculation processing unit; a power control means that controls supply of electric power from said power source unit to said calculation processing unit according to the temperature detected by said temperature detection means; and first and second LEDs that each emit light in a different color, the first LED lighting up to indicate a waiting status when a main switch is switched on for the electronic device, the first LED being extinguished while the second LED is lighting up when an electric power is switched on for an operation of said electronic device, said first and second LEDs being not lit simultaneously, wherein when the temperature that is detected by the temperature detection means is normal, in the waiting status the first LED lights up while the second LED is not lit and during said operation the first LED is extinguished while the second LED lights up, and wherein when the temperature is abnormal, the second LED is extinguished while the first LED flashes.
