• Handle components and cards with care. Don't 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. Discard used
batteries according to the manufacturer's instructions.
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):
• 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.
Ergonomic Computing Habits
CAUTION: Improper or prolonged keyboard use may result in
injury.
CAUTION: Viewing the monitor screen for extended periods of
time may result in eye strain.
