Abstract
An extended base of a mobile terminal and a power supply management method for the extended base is described herein. When a mobile terminal is inserted into an extended base, an enable circuit of the extended base is electrically connected to the mobile terminal and generates an enable signal, and a switch circuit outputs a voltage under control of the enable signal, so that a power supply of the extended base supplies power under control of the voltage. When the mobile terminal is removed from the extended base, the enable circuit stops generating the enable signal, and the switch circuit stops outputting the voltage, so that the power supply cannot supply power under the control of the voltage.
