Appendix D. Customer replaceable units (CRUs)

Customer Replaceable Units (CRUs) are computer parts that can be

upgraded or replaced by the customer. There are two types of CRUs:

internal and external. External CRUs are easy to install, whereas internal

CRUs require some technical skills and in some cases might require tools

such as a screwdriver. However, both internal and external CRUs are safe

for removal by the customer.

Customers are responsible for replacing all external CRUs. Internal CRUs

can be removed and installed by customers or by a Lenovo service

technician during the warranty period.

Your computer contains the following types of external CRUs:

• External CRUs (pluggable): These CRUs unplug from the computer.

Examples of these types of CRUs include the AC adapter and power

cord.

• External CRUs with latches: These CRUs include a latch to help you

remove and replace the part. Examples of these types of CRUs include

the notebook main battery and a hard-disk drive.
