Abstract
An expansion unit has a connector for docking a portable computer. A value of a specific pin of the connector is set in a connection identification register arranged in the expansion unit. When the portable computer is started, it reads the content of the identification register, and checks if a resume mode is set. When it is determined that the expansion unit is connected, and the resume mode is set, a message indicating that the expansion unit is connected is displayed on a display device for a predetermined period of time.
