CHAPTER 3: Replacing notebook components
52
Preventing static electricity discharge
The components inside your notebook are extremely sensitive to static electricity, also
known as electrostatic discharge (ESD).
Before performing maintenance on the notebook, 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.
Tape
Some of the procedures in this guide involve removing tape that holds cables or
components. Two types of tape are used in this notebook:
• Mylar, non-conductive tape is typically transparent, with a red or brown tint.
• Conductive tape is typically grey or silver.
If the existing tape cannot be reused, replace it with the same type (conductivity) of tape.
Both types of replacement tape should be non-ESD generating tape.
Do not use cellophane tape.
Warning
To avoid exposure to dangerous electrical voltages and moving parts, turn off your
notebook, remove the battery, 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 the
notebook.
Important
Before performing maintenance on the notebook, you should read and understand
the information in this section.
