discharge-sensitive components in your notebook. Prevent ESD damage by following ESD guidelines every time you replace the keyboard.

bare metal part of your workbench or other grounded connection.

Before working with notebook 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.
