Abstract
A personal computer system comprises a notebook type personal computer and an expansion device to which the personal computer is removably docked. The expansion device comprises a wired LAN interface. The personal computer comprises a wireless communication interface, a docking detector, and a device driver communicating with another device by the LAN interface when docking is detected, and by the wireless communication interface when undocking is detected.
Claims22
An electronic apparatus system comprising:
- an expansion unit comprising a first communication device for communicating with an external device based on a first communication system;
- and
- an electronic apparatus which is connectable with said expansion unit and comprises a second communication device for communicating with the external device based on a second communication system, a detector configured to detect connection with and disconnection from said expansion unit, and a communication controller configured to be able to communicate with the external device by said first communication device when said detector detects connection with said expansion unit, and communicate with the external device by said second communication device when said detector detects disconnection from said expansion unit.
An electronic apparatus which is connectable with an expansion unit for providing a device which is not provided in the electronic apparatus, the expansion unit comprising a first communication device for communicating with an external device based on a first communication system, the electronic apparatus comprising:
- a second communication device for communicating with the external device based on a second communication system;
- a detector configured to detect connection with and disconnection from said expansion unit;
- and
- a communication controller configured to be able to communicate with the external device by said first communication device when said detector detects connection with said expansion unit, and communicate with the external device by said second communication device when said detector detects disconnection from said expansion unit.
A communication method between an electronic apparatus system and an external device, the electronic apparatus system comprising an electronic apparatus and an expansion unit comprising a first communication device for communicating with the external device based on a first communication system, the electronic apparatus being connectable with said expansion unit and comprising a second communication device for communicating with the external device based on a second communication system, the method comprising:
- detecting connection and disconnection between said expansion unit and electronic apparatus;
- communicating with the external device by said first communication device when connection is detected, and by said second communication device when disconnection is detected.
