1. Perform an orderly computer shutdown using the operating system menu.
2. Turn off your computer and any devices.
3. Ground yourself by touching an unpainted metal surface on the chassis, such as the metal around the card-slot openings at the back of the
computer, before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that might harm
internal components.
4. Disconnect your computer and devices from their power sources. Also, disconnect any telephone or telecommunication lines from the
computer.
Doing so reduces the potential for personal injury or shock.
In addition, take note of these safety guidelines when appropriate:
l
When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with
locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull connectors
apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, make sure both connectors are
correctly oriented and aligned.
l
Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal
mounting bracket. Hold a component such as a microprocessor chip by its edges, not by its pins.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before
you touch any of your computer's electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface on
the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have
accumulated.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
l
When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material
until you are ready to install the component in your computer. Just before unwrapping the antistatic packaging, be sure to discharge static
electricity from your body.
l
When transporting a sensitive component, first place it in an antistatic container or packaging.
l
Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
