1
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 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.
