Which of the following is an example of a Customer Replaceable Unit (CRU) for a laptop computer?

A Customer Replaceable Unit (CRU) is a component of a computer that the end user is authorized to replace without voiding the warranty. This typically includes parts that are designed to be easily accessible and can be replaced by the customer with minimal technical skill.

The keyboard is an example of a CRU because it is often designed to be user-replaceable in many laptop models. The manufacturer provides guidelines on how to replace it safely, which empowers users to maintain their devices without needing to send them in for service. This increases convenience and ensures that common issues, such as a malfunctioning keyboard, can be resolved quickly.

While a battery, RAM, and hard drive are also components that can sometimes be user-replaceable, their classification as CRUs can vary depending on the laptop model. Some laptops have sealed casings or require specialized tools to replace these components, which can lead to these parts being classified as Non-Customer Replaceable Units (NCRUs) in certain contexts. Thus, although some may include batteries, RAM, or hard drives as CRUs in specific models, when considering common practices across varying laptops, the keyboard is a more consistent example of a CRU due to its design and accessibility for general users.
