A Tour of Your Computer: Dell Inspiron 4100

Use this connector to attach the optional docking device, also called an advanced port replicator (APR). A docking device, or APR, allows you to easily use external devices with your computer, such as an external keyboard, mouse, or monitor.

See the documentation that came with your docking device for additional information.

PS/2 Connector

HINT: You can use the integrated keyboard and an external keyboard at the same time. When you attach a keyboard or numeric keypad, the integrated numeric keypad is automatically disabled.

Use this connector to attach PS/2-compatible devices, such as a mouse, keyboard, or external numeric keypad.

Shut down the computer before attaching or removing a PS/2-compatible device. If the device does not work, install the device drivers from the floppy disk or CD that came with the device, and restart the computer.

On an external keyboard, the key acts the same way as the key on the computer's keyboard (if the External Hot Key option is enabled in the system setup program).

USB Connector

Use this connector to attach USB devices, such as a mouse, keyboard, or printer.

Video Monitor Connector

Use this connector to attach an external monitor.
