Disconnect your computer and all attached devices from electrical outlets, and then press the
4
power button to ground the system board.
NOTICE:
Before touching anything inside your computer, ground yourself by touching an unpainted
metal surface, such as the metal at the back of the computer. While you work, periodically touch an
unpainted metal surface to dissipate any static electricity that could harm internal components.
In addition, take note of these safety guidelines when appropriate:
•
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, ensure that both connectors are correctly oriented and aligned.
•
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
processor 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 processor. 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):
•
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.
•
When transporting a sensitive component, first place it in an antistatic container or
packaging.
•
Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and
workbench pads.
