Preparing your w ork space
Before performing maintenance on your computer, make sure that your work
space and your computer are correctly prepared.
■ Wear a grounding (ESD) wri st strap.
■ Use a grounded or dissipative work mat.
■ Use a stable and strong t able.
■ 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
Preventing static electricity
discharge
The components inside your computer are extremely sensitive to static
electricity, also known as electrostatic dis charge (ESD).
Caution ESD can permanently damage electrostatic
discharge-sensitiv e components in y our computer . Prev ent
ESD damage by following ESD guidelines every time you
open the computer case.
Warning To avoid exposure to dangerous electrical voltages and
moving parts, turn off your c omputer and unplu g the power
cord and modem cable before opening the case.
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.
Warning To prevent ri sk of el ectr ic s hock, do n ot in ser t any objec t
into the vent holes of the power supply.
■ 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 an d components on the Mini-P CI
cards. Never slide Mini-PCI cards or components over any surface.
