What Is A Field Replaceable Unit In Laptop And What Are Its Purposes?

A field replaceable unit (FRU) is a part of a laptop that can be removed and replaced by the user without sending the entire laptop to a repair facility. Common FRUs include the battery, hard drive, optical drive, memory, and wireless card.

By design, FRUs are meant to be easy to remove and replace, often requiring only a Phillips head screwdriver. The purpose of having FRUs is twofold: first, it allows the user to easily replace common parts that tend to fail;

Second, it allows the manufacturer to easily diagnose and repair laptops that have been returned for service. For example, if a customer reports that their laptop won’t turn on, the manufacturer can quickly check if the issue is with the battery (a common FRU) by simply replacing it with a known good one.

It’s always best to check with the manufacturer before attempting to replace any part of your laptop.
