20090194520 | DEVICE AND METHOD FOR KEEPING BATTERY PACK OF PORTABLE COMPUTER AT OPERABLE TEMPERATURE - A device for keeping battery pack of portable computer at operable temperature includes a battery pack for supplying power to the portable computer; a thermal sensor installed in the battery pack for sensing a battery temperature; a heating film installed tightly close to the battery pack; and a microprocessor connected to the thermal sensor for receiving the battery temperature sensed by the thermal sensor. When detecting the battery temperature is lower than a first predetermined temperature, the microprocessor enables the battery pack to connect to and supply power to the heating film for heating the battery pack. When detecting the battery temperature is higher than a second predetermined temperature, the microprocessor enables the battery pack to disconnect from the heating film. The first predetermined temperature is lower than a minimum operable temperature and the second predetermined temperature is higher than the first predetermined temperature. | 08-06-2009 |
20090198387 | PORTABLE COMPUTER AND METHOD FOR PREHEATING PORTABLE COMPUTER BEFORE BOOTING - 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. | 08-06-2009 |
20100301674 | CONTROL CIRCUIT AND ELECTRONIC DEVICE INCLUDING THE SAME - This invention provides a control circuit and an electronic device including the same. The control circuit is disposed in an electronic device for connecting a power supply. The electronic device includes a battery module. The control circuit includes a detecting unit, a processing unit, a control unit, and a switch. When the power supply is connected to the electronic device, the detecting unit provides a detecting result. The processing unit determines a type of the power supply according to the detecting result. When the processing unit determines that the power supply is a solar power adapter, the processing unit outputs a first control signal and a turn-off signal. The control unit controls operation of the battery module according to the first control signal. Further, the switch is turned off according to the turn-off signal, preventing the power supply from supplying power to the electronic device. | 12-02-2010 |
