Before performing maintenance on the notebook, make sure that your work
space and the notebook are correctly prepared.
■ Wear a grounding (ESD) wrist strap, and use a grounded or dissipative
work mat.
■ Use a stable and strong table, and 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.
■ 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 do 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 boxes 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 your work surface, stand
them on their heads to prevent the screws from rolling off the table.

batteries, and unplug the power cord,

section.
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.
Some of the procedures in this guide involve removing tape that holds cables
or components. Two types of tape are used in this Gateway 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
Preparing the notebook
To prepare the notebook for maintenance:
1 Make sure that the disc drive is empty.
2 Turn off the notebook.
3 Disconnect from the optional port replicator. For more information, see
“Disconnecting from the port replicator” on page 6.
4 Disconnect the AC adapter, modem cable, and network cable if they are
connected to the notebook.
5 Disconnect all peripheral devices connected to the notebook and remove
any PC cards.
6 Remove the main battery and optional secondary battery. For more
information, see “Removing the batteries” on page 6.
5 If you are removing a module, gently press outward on the clip at each
end of the memory module until the module tilts upward.
6 Pull the memory module out of the slot.

7 Hold the new or replacement module at a 30-degree angle and press it
into the empty memory slot. This module is keyed so it can only be
inserted in one direction. If the module does not fit, make sure that the
notch in the module lines up with the tab in the memory bay.
8 Replace the memory bay cover, then tighten the cover screws.

4 Use the thumb notch to lift the memory bay cover, then remove it. Be
careful not to break off the tabs located on the end of the cover opposite
of the thumb notch.
5 Loosen the three or four screws (these screws cannot be removed) that
secure the cooling assembly to the system board. Use the numbers
stamped in the metal next to each screw and loosen the screws in reverse
numerical order (start with 4, then 3, then 2, then 1).
6 At the same time as you lift, move the cooling assembly away from the
side of the notebook.
