Lenovo ThinkPad L440 Screen Replacement

Introduction

Use this guide to replace the screen on your Lenovo ThinkPad L440 laptop.

The screen is a vital component to the laptop, allowing the user to see visual representations on the computer. A failing screen will prevent you from accessing your computer. Some signs that your screen is failing are flickering, drawn out colors, a burnt display or burnt pixels. Also, if the screen has been previously cracked, this guide will fix this.

Note, if your screen is cracked from dropping the laptop, or your screen no longer works from water damage, this guide may not fix any screen related issues.

Before using this guide, consult our troubleshooting page. In some cases, what looks like a faulty screen can actually be related to outdated software, or too many background applications.
