Introduction

This guide covers how to replace the hinges for the Samsung Series 5 NP540U3C-A02UB.

The hinges allow the laptop to open and close for compact storage, and provide a customizable screen angle. However, as the joint between the display assembly and bottom of the laptop, they are a common failure point of the laptop. If the device has trouble or fails to open or close properly, see our troubleshooting guide for possible causes and solutions before attempting to replace the hinges.

While replacing the hinges, the laptop should always be supported from underneath. The hinges are designed to bear the full weight of the display assembly, and when they are not attached, the wires connecting the display can be pulled loose or broken.
