Appendix A. CRU instructions Customer Replaceable Units (CRUs) are parts that can be upgraded or replaced by the customer. If a CRU is determined to be defective during the warranty period, a replacement CRU will be provided to the customer. Customers are responsible for installing the self-service CRUs for this product. Customers also can install optional-service CRUs, which might require some technical skills or tools, or request that a technician install the optional-service CRU under the terms of the applicable warranty service type for your country or region. Notes: • The illustrations used in this chapter are of the Lenovo M5400, unless otherwise stated. • The illustrations in this manual might differ from the actual product. Please refer to the actual product. Replacing the battery pack Note: Use only the battery provided by Lenovo. Any other battery could ignite or explode. To replace the battery pack, do the following: 1 Turn off the computer. Disconnect the AC power adapter and all cables from the computer. 2 Close the computer display, and turn the computer over. 28
