Appendix B. Customer Replaceable Units (CRUs)

Customer Replaceable Units (CRUs) are computer parts that the customer can

upgrade or replace. There are two types of CRU: self-service and

optional-service. Self-service CRUs are easy to install. They may be standalone

or latched, or require a screwdriver to remove a maximum of two screws,

whereas optional-service CRUs require some technical skill, as well as tools

such as a screwdriver. However, both self-service and optional-service CRUs

are safe for the customer to remove and replace.

Customers are responsible for replacing all self-service CRUs. Optional-service

CRUs can be removed and installed by customers or, during the warranty

period, by a Lenovo service technician.

Lenovo notebook computers contain both self-service and optional-service

CRUs:

v Self-service CRUs: these CRUs can be unplugged, or are secured by no

more than two screws. Examples of this type of CRU are the AC adapter,

the power cord, the battery, and the hard drive. In some products, such

components as memory, wireless cards, notebook keyboards, and palm rests

with fingerprint reader and touchpad may also be CRUs.

v Optional-service CRUs: these CRUs are isolated parts within the computer

that are concealed by an access panel, which is typically secured by more

than two screws. Once the access panel is removed, the CRU is visible. Both

types of CRU are listed in the table on the following page.
