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 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, 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 between the DIMM sockets. If the LED is illuminated, the system still has power.
Power off the computer and remove the power cord before proceeding.
