Preparing your work space
Before performing maintenance on your computer, make sure that your work 
space and your computer are correctly prepared.
■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 back of your 
work surface (behind your computer) or far enough to the side that your 
arms do not accidentally brush components or screws 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.
■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
www.gateway.com
Preventing static electricity 
discharge
The components inside your computer are extremely sensitive to static 
electricity, also known as electrostatic discharge (ESD).
Before opening the computer case, follow these guidelines:
■Turn off the computer power.
■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.
■Unplug the power cord and modem and network cables.
Before working with computer 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.
■Avoid touching the edge connectors and components on the Mini-PCI 
cards. Never slide Mini-PCI cards or components over any surface.
CautionESD can permanently damage electrostatic 
discharge-sensitive components in your computer. Prevent 
ESD damage by following ESD guidelines every time you 
open the computer case.
WarningTo avoid exposure to dangerous electrical voltages and 
moving parts, turn off your computer and unplug the power 
cord and modem cable before opening the case.
WarningTo prevent risk of electric shock, do not insert any object 
into the vent holes of the power supply.
