About Your Computer

For example, you must connect most devices to a particular

I/O

port or

connector to operate properly. Also, external devices like a printer

usually require you to load device drivers before they will work.

When connecting a

USB

mouse or keyboard, ensure that you connect

to one of the Port 1 USB connectors on the back of the computer.

Always attach external devices while your computer is turned off. Then

turn on the computer before turning on any external devices, unless

the documentation for the device specifies otherwise.

NOTICE:

Before disconnecting a device from the computer, wait 10 to 20

seconds after turning off the computer to avoid possible damage to the system
board.

Serial Port Connectors

Default

serial port

designations:

COM1

for port 1 and COM2 for port 2.

You can reassign the serial port's designation in

system setup

if you add an

expansion card containing a serial port using this designation.

If you set the computer’s serial ports to Auto in

system setup

and add an

expansion card containing a serial port configured to a specific designation,
the computer automatically maps (assigns) the integrated ports to the
appropriate COM setting as necessary.

Before you add a card with a serial port, check the documentation that
accompanied your software to ensure that the software can be mapped to
the new COM port designation.

Parallel Port Connector

parallel port

designation:

NOTE:

The integrated parallel port is automatically disabled if the computer

detects an installed expansion card containing a parallel port configured to the
same address as specified in the Parallel Port option in

system setup

.
