that can help you diagnose a problem with your computer.
When you connect external devices to your computer's front panel, follow
these guidelines:
Check the documentation that accompanied the device for specific
installation and configuration instructions.
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.
