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.
