The Dock I provides expandability for your IBM ThinkPad notebook
models (hereinafter referred to as the computer), while providing the
same usability as a desktop computer system. Option cables
connected or disconnected to your computer can be connected to the
Dock I so you can easily carry your computer.
Because the Dock I is designed to be both multimedia-oriented and
portable, for example, you can give presentations at a customer’s
office more effectively with the full-motion images and stereo sound
of multimedia material.
The Dock I has enhanced security features to protect it from being
used by unauthorized persons.
The following summarizes the standard features or options on the
Dock I.
