Preparing your work space
Before performing maintenance on your notebook, make sure that your work
space and your notebook are prepared correctly.
■ Wear a grounding (ESD) wrist strap.
■ Use a grounded or dissipative work mat.
■ Use a stable and strong table.
■ Make sure that the table top is large enough to hold each component as
you remove it.
■ Use bright lighting to make part identification easier.
■ Keep your work surface free from clutter and dust that may damage
components.
■ Use a magnetized screwdriver for removing screws.
■ As you remove components and screws, lay them toward the rear of your
work surface (behind your notebook) or far enough to the side that your
arms do not accidentally brush components onto the floor.
Preparing your work space
■ 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 boxes on the page. Where screw measurements
are shown, the first number indicates screw head width, and the
second number indicates screw length.
■ After loosening screws that are deeply recessed in a hole (for
example, on the bottom of the base assembly or on the cooling
assembly), you can leave the screws in the holes if you place small
pieces of tape over the hole openings. When reassembling the
component, just remove the tape and tighten the screws.
■ When you place flat-headed screws on your work surface, stand
them on their heads to prevent the screws from rolling off the table.

Chapter 1: Replacing Components in Your Gateway 400
Preventing static electricity discharge
The components inside your notebook are extremely sensitive to static
electricity, also known as electrostatic discharge (ESD).
Caution ESD can permanently damage electrostatic discharge
sensitive components in your notebook. Prevent ESD
damage by following ESD guidelines every time you open
your notebook case.
Warning To avoid exposure to dangerous electrical voltages and
moving parts, turn off your notebook, remove the battery,
and unplug the power cord and modem cable before
opening the case.
Before replacing components, follow these guidelines:
■ Turn off your notebook power.
■ Remove the battery and unplug the power cord.
■ Disconnect all peripheral devices and remove any PC Cards.
■ 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.
■ 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 memory modules and modems by their edges, but avoid
touching the edge connectors and components on the cards.
■ Never slide any component over any surface.
Warning To prevent risk of electric shock, do not insert any object
into the vent holes of your notebook.
