Abstract
There are provided a power supplying system, an electronic apparatus, and a power supplying method capable of surely preventing an abnormal end even in a case where supply of external power is disconnected in an apparatus having no battery with a valid voltage. The supply system includes a first power feed unit () that preferentially outputs external power rather than internal power from a first battery () in an electronic apparatus (), a second power feed unit () that preferentially outputs the external power rather than internal power from a second battery () in a connection apparatus (), an external power feed connection unit (external power feed connection path (L)) that connects an external power feed path (L) to the first power feed unit () and an external power feed path (L) to the second power feed unit (), a selection unit () that selects one of the first power feed unit () and the second power feed unit (), and a control unit () that causes the selection unit () to select a power feed unit that receives the internal power between the first power feed unit () and the second power feed unit ().
