Knowing the Parts
External Monitor Port
The 15-pin D-sub monitor port supports a standard VGA-compatible device such as a monitor or pro-
jector to allow viewing on a larger external display.
USB Ports
Universal Serial Bus (USB) supports many USB compatible devices such as keyboards, pointing de-
vices, video cameras, modems, hard disk drives, printers, monitors, and scanners connected in a series
up to 12Mbits/sec. USB allows up to 127 devices to run simultaneously on a single computer, with
peripherals such as USB keyboards and some newer monitors acting as additional plug-in sites or hubs.
USB supports hot-swapping of devices so that peripherals can be connected or disconnected while the
Notebook PC is ON.
PS/2 Port
The PS/2 port is for connecting an external PS/2 mouse or PS/2 keyboard to the Notebook PC if you do
not want to use the built-in pointing device and keyboard. Simultaneous use of two PS/2 devices re-
quires an optional PS/2 Y-adapter. It is recommended that you use either a USB mouse or a USB
keyboard so that dual PS/2 connections are not required.

compatible Note-
book PC security products. These security products usually include a metal cable and lock that prevent
the Notebook PC to be removed from a fixed object. Some security products may also include a motion
detector to sound an alarm when moved.
