Solving Hardware Installation Problems
You may need to reconfigure the computer when you add or remove hardware, such as an additional
drive or expansion card. If you install a plug and play device, Windows XP automatically recognizes the
device and configures the computer. If you install a non–plug and play device, you must reconfigure the
computer after completing installation of the new hardware. In Windows XP, use the
Add Hardware
Wizard
and follow the instructions that appear on the screen.
WARNING!
When the computer is plugged into an AC power source, voltage is always applied to the
system board. To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure
to disconnect the power cord from the wall outlet and allow the internal system components to cool
before touching.
Look for the LED on the system board. If the LED is illuminated, the system still has power. Power off
the computer and remove the power cord before proceeding.
