After working with parts, you need to replace the computer cover and reconnect any cables, including telephone lines and power cords. Also, depending on the part that was replaced, you might need to confirm the updated information in the Setup Utility program. See "Starting the Setup Utility" in your Quick reference or in the Hardware Maintenance Manual.
