Abstract
A method and system for supplying external electrical power to charge a battery within a data processing system by utilizing a automated remotely located power adapter is disclosed. The automated remotely located power adapter includes a state control logic circuit for determining when to supply external electrical power to charge the battery and an auto-close detection circuit for automatically shutting on and off the external electrical power in response to the state control logic. The automated remotely located power adapter is connectable between the external power supply and the data processing system for supplying external electrical power to charge the battery within the data processing system and automatically shuts off the external electrical power when the data processing system indicates that the battery is fully charged.
