Before replacing hardware

Attention: Do not open your computer or attempt any repairs before reading this section and the Important Product Information Guide.

Notes before replacing hardware

  • 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 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 part until the defective part has been removed and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage computer components and options.

When you handle options and other computer components, take these precautions to avoid static-electricity damage:
  • Limit your movement. Movement can cause static electricity to build up around you.

  • Always handle options and other computer components carefully. Handle PCI/PCIe cards, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.

  • Prevent others from touching the options and other computer components.

  • 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 from the package and your body before you install or replace a new part.

  • When possible, remove the new part from the static-protective package, and install it directly in the computer without setting the part down. When this is not possible, place the static-protective package on a smooth, level surface and place the part on the package.

  • Do not place the part on the computer cover or other metal surface.
