Lenovo 3000 J Series - Manual (Page 34)

When you add an option, do not open the static-protective package containing the
option until you are instructed to do so.
When you handle options and other computer components, take these precautions
to avoid static electricity damage:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Always handle components carefully. Handle adapters and memory modules by
the edges. Never touch any exposed circuitry.
v Prevent others from touching components.
v When you install a new option, touch the static-protective package containing
the option to a metal expansion-slot cover or other unpainted metal surface on
the computer for at least two seconds. This reduces static electricity in the
package and your body.
v When possible, remove the option and install it directly in the computer without
setting the option down. When this is not possible, place the static-protective
package that the option came in on a smooth, level surface and place the option
on it.
v Do not place the option on the computer cover or other metal surface.
Installing external options
This section shows the various external connectors on your computer to which you
can attach external options, such as external speakers, a printer, or a scanner. For
some external options, you must install additional software in addition to making
the physical connection. When adding an external option, use the information in
this section to identify the required connector, and then use the instructions that
come with the option to help you make the connection and install any software or
device drivers that are required for the option.
