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.
