Power adaptation device and power supply management method

A power adaptation device, applicable to supplying power to an electronic device, comprising:

• a terminal seat;
• a detection contact, disposed at the terminal seat;
• an electric power modulation unit, wherein the electric power modulation unit is electrically connected to an external power;
• a control unit, coupled to the electric power modulation unit;
• and
• a detection unit, coupled to the detection contact and the control unit, wherein the detection unit judges that the power adaptation device is connected to the electronic device or is not connected to the electronic device according to a voltage level of the detection contact and notifies the control unit;
• wherein when the power adaptation device is connected to the electronic device, the control unit controls the electric power modulation unit to modulate the external power to supply power and drive the electronic device;
• and
• when the power adaptation device is not connected to the electronic device, the control unit controls the electric power modulation unit to reduce a total power consumption.

A power adaptation device, comprising:

• a terminal seat;
• a detection unit, fixedly sleeved over the terminal seat;
• a probing terminal, partially embedded in the terminal seat and movably located between a power-on position and a power-off position, wherein the probing terminal is separated from the detection unit at the power-on position, and the probing terminal contacts and is conducted with the detection unit at the power-off position;
• an electric power modulation unit, connected to an external power to provide a voltage source;
• and
• a control unit, connected to the probing terminal, the detection unit, and the electric power modulation unit, so as to sense whether the probing terminal is located at the power-on position or the power-off position, and control the electric power modulation unit to supply power or stop supplying power;
• wherein when the probing terminal is located at the power-off position, the control unit controls the electric power modulation unit to turn off and stop supplying the voltage source, and when the probing terminal is located at the power-on position, the control unit controls the electric power modulation unit to supply the voltage source.
