Before replacing hardware
Attention
Do not open your computer or attempt any repairs before reading the
Important
Product Information Guide
.
Read these notes before replacing hardware:
• Some of the hardware components explained in this manual are optional.
• Use computer components provided only by Lenovo.
• When installing or replacing an option, use the appropriate instructions explained in this manual along
with the instructions that come with the option.
• In most areas of the world, Lenovo requires the return of defective Customer Replaceable Units (CRUs).
Information about this will come with the CRU or will come a few days after the CRU arrives.
Handling static-sensitive devices
Do not open the static-protective package containing the new component until the defective component
has been removed and you are ready to install the new component. Static electricity, although harmless to
you, can seriously damage computer components.
When you handle parts and other computer components, take these precautions to avoid static damage:
• Limit your movement. Movement can cause static electricity to build up around you.
•
Always handle computer components carefully. Handle PCI/PCI-Express cards, memory modules,
system boards, and microprocessors by the edges. Never touch any exposed circuitry.
• Prevent others from touching the parts and other computer components.
•
Touch the anti-static package containing the component to a metal expansion-slot cover or other
unpainted metal surface on the computer for at least two seconds. This reduces static electricity from
the package and your body before you install or replace a component.
•
When possible, remove the new component from the anti-static package, and install it directly in the
computer without setting the part down. When this is not possible, place the anti-static package that the
component came in on a smooth, level surface and place the component on the package.
• Do not place the component on the computer cover or any other metal surface.
