CHAPTER 3: Replacing notebook components
Preventing static electricity discharge
Warning
To avoid exposure to dangerous electri cal voltages and moving
parts, turn off your notebook, remove the battery, and unp lug the
power cord and network cable before opening the case.
Warning
To prevent risk of electric shock, do not insert any object i nto the
vent holes of the notebook.
Important
Before performing maintenance on the notebook, you shoul d read
and understand the information in this section.
The components inside your notebook are ex tre mely sensitive to st atic e lectricity,
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 att ach
it to a bare metal part of your workbench or other grounded connection.
• Touch a bare metal surface on your workbench or other gr ounded object.
Tape
48
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.

Preparing the work space
Before performing maintenance on the notebook, make sure that your work space
and the notebook are correctly prepared.
• Wear a grounding (ESD) wrist strap, a nd use a grounded or dissip ative work
mat.
• Use a sturdy table. Make sure that the t able top is wide e nough to hold each
component as you remove it.
• Ensure that clear lighting condition is available to make part identification
easier.
• Keep your work surface free from clutter and debris that may damage
components.
• Use a magnetized screwdriver for removing screws.
• When removing components that are attached to the notebook by a cable,
unplug the cable before removing the screws, when possible, to avoid
damaging the cable.
• As you remove components and screws, lay them toward the rear of your
work surface (behind the notebook) or far enough to the side that your arms
will not accidentally brush them onto the floor.
• To help keep track of screws, try the following:
– Place each component’s screws in their own section of a parts sorter.
– Place each component’s screws next to the component on your work
surface.
– Print the first page of each task, then place the page toward the rear of
your work surface. As you remove screws, place the screws in their
respective section on the page.
– After loosening screws that are deeply recessed in a hole (for example,
on the bottom of the base assembly), you can leave the screws in the
holes if you place small pieces of masking tape over the hole openings.
When reassembling the component, just remove the tape and tighten
the screws.
– When you place flat-headed screws on the work surface, stand them
on their heads to prevent the screws from rolling off the table.
