Method and system for remotely supplying power through an automated power adapter to a data processing system

A system for supplying electrical power to a data processing system having an internal battery, comprising:

• an external power supply for supplying external electrical power to charge said internal battery via a power adapter coupled between an external power supply and said data processing system;
• input means within said remotely located power adapter for receiving an indication from said data processing system that said internal battery is fully charged;
• and
• means for automatically shutting off said external electrical power utilizing said remotely located power adapter in response to said indication.

A circuit for remotely supplying electrical power, comprising:

• a remotely located power adapter connectable between an external power supply and a data processing system for supplying external electrical power to charge a battery within said data processing system;
• input means for receiving an indication of whether or not to supply said external electrical power to charge said battery
• a state control logic circuit, coupled to said input means, disposed within said remotely located power adapter for receiving said indication;
• and
• an auto-close detection circuit, coupled to said state control logic, disposed within said remotely located power adapter for automatically shutting on and off said external electrical power in response to said state control logic.
