ABSTRACT:
A power supply control apparatus (113) for an electronic device (102) includes a terminal (115) to couple to a battery (103), a connector (122) to couple to an external power supply (172), a switch circuit (140) coupled to the terminal (115) and the connector (122), and a controller (108) coupled to the switch circuit (140). The switch circuit (140) connects the terminal (115) to power the electronic device (102) from the terminal (115) when the battery (103) is attached and disconnects the terminal (115) to power the electronic device (102) from the connector (122) when the external power supply (172) is attached. The controller (108) selectively controls the switch circuit (140) to connect the connector (122) to the terminal (115) so as to charge the battery (103) from the external power supply (172).
