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 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 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 parts and other 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 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 that 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 hardware 10 Knowing replaceable parts Customer-Replaceable Units (CRUs) CRUs are computer parts that a user can upgrade or replace. There are two types of CRUs: self-service and optional-service. Self-service CRUs You 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 USB device, and the power cord. Other self-service CRUs might include memory modules, adapter cards, hard disk drives, and optical drives. Note Optional-service CRUs Users are responsible for replacing all self-service CRUs. Handling optional-service CRUs requires some technical skills and simple tools (such as a screwdriver). These CRUs are isolated parts within the computer. They are usually concealed by an access panel that is secured by more than two screws. You must remove the screws and panel to access the specific CRU. Optional-service CRUs can be removed and installed by users or, during the warranty 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 to: http://www.lenovo.com/serviceparts-lookup Replacing hardware 11 CRUs and FRUs locations Refer to the following illustrations to check the locations of CRUs and FRUs within the computer.

After completing the installation or replacement for all parts, reinstall the computer cover and reconnect the cables. To reinstall the computer cover and reconnect the cables to your computer, do the following: 1 Ensure that all components have been reassembled correctly and that no tools or loose screws are left inside your computer. 2 Ensure that the cables are routed correctly before reinstalling the computer cover. Keep cables clear of the hinges and sides of the computer chassis to avoid interference when reinstalling the computer cover. 3 Install the computer cover. 4 Install the screw to secure the computer cover. 5 If a locking device is available, use it to lock the computer. 6 Reconnect the external cables and power cords to the corresponding connectors on the computer. Replacing customer-replaceable units (CRUs) 40 Replacing field-replaceable units (FRUs) Before replacing FRUs Before replacing an FRU (Field Replaceable Unit), read the following: •• Only certified and trained personnel can service the computer. •• Before replacing an FRU, read the entire section on replacing the part. •• Be extremely careful during writing operations such as copying, saving, or formatting. The sequence of the drives in the computer that you are servicing might have been altered. If you select an incorrect drive, data or programs might be overwritten. •• Replace an FRU only with another FRU of the correct model. When you replace an FRU, ensure that the model of the machine and the FRU part number are correct by referring to the website: http://www.lenovo.com/serviceparts-lookup •• An FRU should not be replaced because of a single, unreproducible failure. Single failures can occur for a variety of reasons that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge, or software errors. Consider replacing an FRU only when a problem recurs. If you suspect that an FRU is defective, clear the error log and run the test again. If the error does not recur, do not replace the FRU. •• Only replace a defective FRU. To identify the FRU type of a computer component, see CRUs and FRUs locations.
