Chapter 2. Installing options and replacing hardware This chapter provides instructions for installing options and replacing hardware for your computer. You can expand the capabilities of your computer by adding memory modules, adapter cards, or drives. When installing or replacing an option, use these instructions along with the instructions that come with the option. Handling static-sensitive devices Do not open the static-protective package containing the new part until the defective part has been removed from the computer and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage computer components and parts. When you handle parts and other computer components, take these precautions to avoid static-electricity damage: v Limit your movement. Movement can cause static electricity to build up around you. v Always handle parts and other computer components carefully. Handle adapter cards, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry. v Prevent others from touching the parts and other computer components. v Before you replace a new part, touch the static-protective package containing the part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity in the package and your body. v When possible, remove the new part from the static-protective packaging, and install it directly in the computer without setting the part down. When this is not possible, place the static-protective package that the part came in on a smooth, level surface and place the part on it. v Do not place the part on the computer cover or other metal surface.
