CHAPTER 3: Replacing notebook components
44
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 secures 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 in color.
If the existing tape cannot be reused, replace it with the same type. Make sure
the replacement tape is of the non-ESD generating kind. 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 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.
