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.
SAFETY: 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):
• Do not remove components from their antistatic packing material until you are ready to install the component in
your computer. Just before unwrapping the antistatic packaging, discharge static electricity from your body.
• When transporting an electrostatic sensitive component, first place it in an antistatic container or packaging.
• Handle all electrostatic sensitive components in a static-safe area. If possible, use antistatic floor pads and
workbench pads.
SAFETY: 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.
For comfort and efficiency, observe the ergonomic guidelines in your User’s Guide when setting up and using your
computer.
SAFETY: Battery Disposal
Your computer uses a lithium coin-cell battery. The lithium coin-cell battery is a long-life battery, and it is
very possible that you will never need to replace it. However, should you need to replace it, see your User’s
Guide.
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.
