Replacing hardwareBefore replacing hardwareAttentionDo not open your computer or attempt any repairs before reading the ImportantProduct 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 alongwith the instructions that come with the option. In most areas of the world, Lenovo requires the return of defective CRUs (Customer Replaceable Units).Information about this will come with the CRU or will come a few days after the CRU arrives.Handling static-sensitive devicesDo not open the static-protective package containing the new component until the defective componenthas been removed and you are ready to install the new component. Static electricity, although harmless toyou, 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 parts and other computer components carefully. Handle PCI/PCI-Express cards, memorymodules, system boards, and microprocessors by the edges. Never touch any exposed circuitry. Prevent others from touching the parts and other computer components. Touch the static-protective package containing the part to a metal expansion-slot cover or otherunpainted metal surface on the computer for at least two seconds. This reduces static electricity fromthe 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 thecomputer without setting the part down. When this is not possible, place the static-protective packagethat the part came in 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.Replacing hardware10

Knowing replaceable partsCustomer-Replaceable Units (CRUs)CRUs are computer parts that a user can upgrade or replace. There are two types of CRUs: self-service andoptional-service.Self-service CRUsYou can install self-service CRUs easily. These CRUs might be standalone,latched, or secured by up to two screws.Examples of self-service CRUs include the keyboard, mouse, any USBdevice, and the power cord. Other self-service CRUs might include memorymodules, adapter cards, hard disk drives, and optical drives.NoteOptional-serviceCRUsUsers are responsible for replacing all self-service CRUs.Handling optional-service CRUs requires some technical skills and simpletools (such as a screwdriver).These CRUs are isolated parts within the computer. They are usuallyconcealed by an access panel that is secured by more than two screws. Youmust remove the screws and panel to access the specific CRU.Optional-service CRUs can be removed and installed by users or, during thewarranty period, by a Lenovo service technician.Field-Replaceable Units (FRUs)FRUs are computer parts that a trained technician can upgrade or replace.For detailed FRU information, such as the FRU part numbers and supported computer models, go ing hardware11
