Replacing Gateway 400VTX Components

Preparing your work space

Before performing maintenance on your notebook, make sure that your work
space and your 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 your 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. 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), 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.

Preventing static electricity discharge

Preventing static electricity
discharge

The components inside your notebook are extremely sensitive to static
electricity, also known as electrostatic discharge (ESD).

Warning 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 and unplug the power
cord and modem and network cable before opening the
case.

Before replacing components, follow these guidelines:

■ Turn off your notebook.

■ 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.

Warning To prevent risk of electric shock, do not insert any object

into the vent holes of the notebook.

■ Touch a bare metal surface on your workbench or other grounded object.

■ Unplug the power cord and the modem and network cables.

■ Remove the battery. For more information, see “Removing the battery” on

page 8.

■ Disconnect all peripheral devices and remove any PC Cards.

Replacing Gateway 400VTX Components

Before working with notebook components, 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.

Preparing your notebook

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 and network
cables before opening the case. Replace the cover before
you restore power or reconnect the modem and network
cables.

To prepare your notebook for maintenance:

■ Make sure that the DVD drive and the optional diskette drive or optional

card reader are empty.

■ Disconnect all peripheral devices and remove any PC Cards.

■ Turn off your notebook and unplug the power cord and modem and

network cables (if attached).

■ Turn over your notebook and remove the battery.
