Abstract
An electronic device includes a main board and a heat dissipation device, and the heat dissipation device includes a plurality of fans and a micro control unit (MCU). The main board and the plurality of fans are electrically connected to the MCU. The MCU controls the plurality of fans to rotate, and each of the plurality of fans sends a feedback signal to the MCU as long as it is working normally. When a feedback signals from at least one of the plurality of fans in not received, the MCU applies a soft power-off to the main board after storing current data of the electronic device.
Claims11
An electronic device, comprising:
- a main board;
- and
- a heat dissipation device including a plurality of fans and a micro control unit (MCU), the main board and all of the plurality of fans electrically connected to the MCU;
- wherein the MCU controls the plurality of fans to rotate;
- each of the plurality of fans sends a feedback signal to the MCU when each of the plurality of fans works normally;
- and in response to the MCU failing to receive the feedback signals from at least one of the plurality of fans, the MCU controls the main board to turn off.
A method for using an electronic device including a plurality of fans configured for heat dissipation, comprising:
- controlling the plurality of fans to rotate;
- using each of the plurality of fans to generate a feedback signal when each of the plurality of fans works normally;
- receiving the feedback signals from each of the plurality of fans;
- and
- turning off the electronic device when the feedback signals are not received from at least one of the plurality of fans.
