Abstract
An external power supply and a system connection detection unit applied thereto are provided. For providing DC power, the external power supply separably connects with a positive input terminal and a negative input terminal of a system through a positive output terminal and a negative output terminal respectively. When the positive output terminal and the negative output terminal are respectively connected to the positive input terminal and the negative input terminal, a system detection terminal connects with a system connection terminal of the system, and a connection status signal generated by the system connection detection unit switches the operation of the external power supply from a deep sleeping mode to a normal operation mode. The system connection terminal is electrically connected to one of the positive input terminal and the negative input terminal through at least a first resistive element.
