Abstract
An electronic device includes an authentication unit that performs authentication to determine whether a power supply apparatus connected to the electronic device is a predetermined apparatus, a selection unit that makes a user select whether to use the power supply apparatus, when the authentication has failed, a storage unit that stores information indicating that the authentication has succeeded or the user has selected to use the power supply apparatus as history information. When the power supply apparatus is detached from the electronic device, the history information is deleted from the storage unit. The electronic device permits use of the power supply apparatus connected to the electronic device when the history information is stored in the storage unit while the electronic device is in a power ON state.
