constant communication between the USB port and your devices allows you to
connect and disconnect devices without shutting down first.

Figure 6-3: USB Port
You can connect a USB device by plugging the USB cable into the USB port
on the left side of the notebook.
The system should automatically detect the new device and make it available
for you. If the device is not immediately recognized, check the documentation
for the device.
The USB port not only provides a connection between your notebook and the
external devices, but they are also capable of providing electrical current to
run those devices. If you make considerable use of your notebook under
battery power, you should consider how USB devices might drain your battery
or slow battery charging. If you have a USB device that has its own electrical
power source, you should consider using this device as a hub for your other
devices. These devices can then draw power through the hub device, leaving
your notebook free to conserve or recharge battery power.
Using the PS/2 Port
The PS/2 port on the left side of the notebook lets you connect an external
keyboard to your system, such as a full size AT-enhanced keyboard, or an
external pointing device to your system, such as a mouse or a trackball. The
PS/2 device must have a mini-DIN PS/2 connector. If your device uses a larger
AT DIN connector or a 9-pin serial connector, you can easily get an adapter to
change it to a mini-DIN PS/2 connector.
