Introduction

This guide will demonstrate how to take out and replace the motherboard in a Samsung Chromebook Series 3. A motherboard, also known as a logic board, is a circuit board that controls most other components in a laptop. A damaged motherboard might be the culprit behind serious issues such as overheating, Blue Screen Of Death (BSOD), or system components such as RAM not being detected.

Ensure that the laptop is powered off before proceeding with the repair. ESD-safe tools are recommended to prevent any static shock damage.
