Chapter 2. Installing options and replacing hardware
This chapter provides instructions for installing options and replacing hardware for
your computer. You can expand the capabilities of your computer by adding
drives, memory modules, or PCI cards. When installing or replacing an option, use
these instructions along with the instructions that come with the option.
Important: Before you install or replace any option, be sure to read and
understand the “Important safety information” in the
ThinkCentre Safety
and Warranty Guide . The precautions and guidelines will help you work
safely.
Handling static-sensitive devices
Do not open the static-protective package containing the new part until the
defective part has been removed from the computer and you are ready to install
the new part. Static electricity, although harmless to you, can seriously damage
computer components and parts.
When you handle parts 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 parts and other computer components carefully. Handle PCI
cards, memory modules, system boards, and microprocessors by the edges.
Never touch any exposed circuitry.
v
Prevent others from touching the parts and other computer components.
v
Before you replace a new part, touch the static-protective package containing the
part 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 new part from the static-protective packaging, and
install it directly in the computer without setting the part down. When this is
not possible, place the static-protective package that the part came in on a
smooth, level surface and place the part on it.
v
Do not place the part on the computer cover or other metal surface.
Installing options and replacing hardware
