CHAPTER 3: Maintaining and Upgrading Your Notebook www.gateway.com Preventing static electricity discharge Warning To avoid exposure to dangerous electrical voltages and moving parts, turn off your notebook and unplug the power cord, modem cable, and network cable before opening the case. Warning To prevent risk of electric shock, do not insert any object into the vent holes of your notebook. Important Before installing or replacing components, you should read and understand the information in this section. The components inside your notebook are extremely sensitive to static electricity, also known as electrostatic discharge (ESD). Before installing or replacing components, follow these guidelines: ■ Avoid static-causing surfaces such as carpeted floors, plastic, and packing foam. ■ Remove components from their antistatic bags only when you are ready to use them. Do not lay components on the outside of antistatic bags because only the inside of the bags provide electrostatic protection. ■ Always hold components by their edges. Avoid touching the edge connectors. Never slide components over any surface. ■ Wear a grounding wrist strap (available at most electronics stores) and attach it to a bare metal part of your workbench or other grounded connection. ■ Touch a bare metal surface on your workbench or other grounded object.
