Abstract
The invention provides a portable computer. When a power input terminal of the portable computer is connected to a power source, a sensor senses the temperature of electronic components of the portable computer to provide a sensed temperature value. When the sensed temperature value is lower than a preset temperature value, a microprocessor controls an indication device to operate and controls the heating unit to heat the electronic components. 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 stop heating the electronic components.
