This reduces static electricity in the package and your body. • Whenever possible, remove the static-sensitive part from the static-protective packaging and install the part without setting it down. When this is not possible, place the staticprotective packaging on a smooth, level surface and place the part on it. • Do not place the part on the computer cover or other metal surface. Cleaning and Maintenance Keep your computer and workspace clean. Shut down the computer and then disconnect the power cord before cleaning the computer. Do not spray any liquid detergent directly on the computer or use any detergent containing flammable material to clean the computer. Spray the detergent on a soft cloth and then wipe the computer surfaces. Chapter 2. Operating Environment and Other Important Notices 33
