Patent ID: 8078864

Claim:
A portable computer comprising: a power input terminal; a heating unit disposed on an electronic component in the portable computer; a sensor disposed on the electronic component in the portable computer, for sensing the temperature of the electronic component and providing a sensed temperature value; a power button; an indication device; and a microprocessor, operationally coupled to the power input terminal, the heating unit, the sensor, the power button and the indication device, respectively, and receiving the sensed temperature value from the sensor, wherein when the power input terminal is connected to a power source and the power button is pressed, if the sensed temperature value is lower than a preset temperature value, the microprocessor controls the indication device to operate and controls the heating unit to heat the electronic component, and when the sensed temperature value is higher than the preset temperature value, the microprocessor controls the indication device not to operate and controls the heating unit to stop heating the electronic component and the power button is configured to be pressed again to boot the portable computer.
