Customer Replaceable Units
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. The following tables
list CRUs for your computer and tell where to find the replacement instructions.
