Locating FRUs and CRUs This topic introduces the following service parts: • "Major FRUs and CRUs" on page 37 • "LCD FRUs" on page 43 • "Miscellaneous parts and other FRUs" on page 44 Notes: • Each FRU is available for all types or models, unless otherwise specified. • CRU statement for customers: You can resolve some problems with your product with a replacement part you can install yourself, called a "Customer Replaceable Unit" or "CRU." Some CRUs are designated as self-service CRUs and others are designated as optional-service CRUs. Installation of self-service CRUs is your responsibility. For optional-service CRUs, you can either install the CRU yourself or you can request that a Service Provider install the CRU according to the warranty service for your product. If you intend on installing the CRU, Lenovo will ship the CRU to you. CRU information and replacement instructions are shipped with your product and are available from Lenovo at any time upon request. You can find a list of CRUs for your product in this Hardware Maintenance Manual. An electronic version of this manual can be found at http://www.lenovo.com/UserManuals. Follow the on-screen instructions to find the manual for your product. You might be required to return the defective part that is replaced by the CRU. When return is required: (1) return instructions, a prepaid shipping label, and a container will be included with the replacement CRU; and (2) you might be charged for the replacement CRU if Lenovo does not receive the defective CRU within thirty (30) days of your receipt of the replacement CRU. See your Lenovo Limited Warranty documentation for full details. Lenovo computers contain the following types of CRUs: - Self-service CRUs: These CRUs unplug or are held by no more than two screws. Examples of these types of CRUs include the ac power adapter, power cord, and battery. Other self-service CRUs depending on product design might include the memory module, wireless card, keyboard, and palm rest with finger print reader and touch pad. - Optional-service CRUs: These CRUs are isolated parts within the computer that are concealed by an access panel that is typically secured by more than two screws. Once the access panel is removed, the specific CRU is visible. 36 Hardware Maintenance Manual
