∙When installing any upgrade, be sure you understand what the installation procedure involves before you start. This will enable you to plan your work, and so minimise the amount of time that sensitive components are exposed.

∙Do not remove the system unit cover, nor the anti-static bag or wrapping of any upgrade, until you need to.

∙Handle static-sensitive items with extreme care. Hold expansion cards and add-on components only by their edges, avoiding their electrical contacts. Never touch the components or electrical contacts on the motherboard or on expansion cards. In general, do not handle static-sensitive items unnecessarily.

∙Keep all conductive material, foodstuffs and especially liquids, away from your work area and the open computer.
