A heat dissipation apparatus with energy-saving effect is coupled to an operation unit, and the heat dissipation apparatus includes a control unit and a drive circuit. The control unit determines whether the operation unit enters an energy-saving mode according to a first signal provided by the operation unit. The control unit shields a plurality of second signals provided to the drive circuit according to the energy-saving mode. The drive circuit does not drive the heat dissipation unit and the heat dissipation unit enters an inertia deceleration.

The invention provides a method for an electronic device for automatically detecting and identifying a peripheral device. The electronic device comprises a connector having a first pin and a second pin and connects to a peripheral device through the connector. The method comprises the steps of determining whether the peripheral device is connected to the connector; reading a first state of the first pin and the second pin when determining that the peripheral device is connected to the connector; setting a voltage of the first pin to a first voltage level and then reading a second state of the first pin and the second pin; and identifying the peripheral device according to the first state and the second state. The invention also provides an electronic device and an electronic system utilizing the above-mentioned method.

A portable electronic apparatus and a connection method therefore are disclosed. The portable electronic apparatus comprises a connector, a processing circuit, and a switch module. After a plug is plugged into the connector, the processing circuit reads a voltage value of the plug via the switch module. When determining that the voltage value of the plug is within a first voltage range, the processing circuit outputs switch signals to the switch module, so that an input signal of the plug is able to be transmitted to the processing circuit via the connector and the switch module. When determining that the voltage value of the plug is within a second voltage range, the processing circuit outputs other switch signals to the switch module, so that an output signal of the processing circuit is able to be transmitted to the plug via the switch module and the connector.
