Lenovo ThinkCentre M80 Hardware Maintenance Manual for ThinkCentre M80 - Page 80

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 computer parts and components, take these precautions to avoid static-electricity damage: • Limit your movement. Movement can cause static electricity to build up around you. • Always carefully handle the parts and other computer components. Handle PCI cards, memory modules, system boards, and microprocessors by the edges. Never touch exposed circuitry. • Prevent others from touching the parts and other computer components. • Before you replace a new part, touch the static-protective package containing the new part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity from the package and your body. • Remove the new part from the static-protective package and directly install it in the computer without placing it on any other surface. If it is hard for you to do this in your specific situation, place the static-protective package of the new part on a smooth, level surface, and then place the new part on the static-protective package. • Do not place the part on the computer cover or other metal surface. Installing or replacing hardware This section provides instructions on how to install or replace hardware for your computer. You can expand the capabilities of your computer by adding memory modules, PCI cards, or drives, and maintain your computer by replacing the failing hardware. Notes: 1.
