Perform an orderly computer shutdown using the operating system menu.
2
Turn off your computer and any devices connected to the computer.
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, including the monitor, from their electrical
outlets. 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:
• 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 microprocessor chip by its edges, not by its pins.
CAUTION: There is a danger of a new battery exploding if it is incorrectly installed.
Replace the battery only with the same or equivalent type recommended by the
manufacturer. Do not dispose of the battery along with household waste. Contact
your local waste disposal agency for the address of the nearest battery deposit site.
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.
