Attaching a Kensington-style cable lock You can use a Kensington-style cable lock to secure your computer to a desk, table, or other nonpermanent fixture. The cable lock connects to the security-lock slot at the rear of your computer. Depending on the type selected, the cable lock can be operated with a key or combination. The cable lock also locks the buttons used to open the computer cover. This is the same type of lock used with many notebook computers. You can order such a cable lock directly from Lenovo by searching for Kensington at: http://www.lenovo.com/ support. Computer locks 11 Replacing hardware 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 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 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 12 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 Users are responsible for replacing all self-service CRUs. Optional-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 13 CRUs and FRUs locations Refer to the following illustrations to check the locations of CRUs and FRUs within the computer.

Replacing CRUs 37 Replacing FRUs Before replacing FRUs Before replacing any FRU, read the following: •• Only certified and trained personnel can service the computer. •• Before replacing an FRU, read the entire section about 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 check the locations of FRUs, see CRUs and FRUs locations.
