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.
To open the Add Hardware Wizard, open a Command Prompt and open hdwwiz.exe.
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.
A new device is not recognized as part of the system.
