Lenovo ThinkPad X390 Yoga Display Replacement

Introduction

Use this guide to replace the display of a Lenovo ThinkPad X390 Yoga Laptop.

The display/monitor of a device is a crucial piece of computing hardware. It is an output device that displays the information that is being entered/processed on your computer. It generates everything from the images you see, to the videos you watch, to the graphical information from your computer's graphics card, to the text you are reading in this very moment! If your display is somehow damaged or corrupted, however, whether through loose/damaged cables, faulty hardware, damages to the screen itself, etc., it can cause great difficulty when it comes to visibility, and especially basic usability. Your computer's screen may display an error message, have a very blurry or corrupted display, or even not function altogether. A corrupted or damaged monitor is a problem that should be resolved immediately. Luckily, this guide will help you do just that!

Before taking a look at this guide, it is highly recommended that you visit the Lenovo monitor/display troubleshooting page, to confirm whether the issue with your display requires you to replace it with a new one or not.

This task will be much more difficult and risky if you are simply are using your hands or home tools. It is strongly recommended that your purchase a laptop opening tool and spudger prior to beginning this process. You can purchase both of these with an assurance of high-quality, affordable price, and great reviews, from Ifixit. The opening tool is known as the Ifixit Jimmy, and a pack of 3 Ifixitit spudgers can also be purchased.

It is crucial that you perform a system backup of your laptop prior to beginning this process, so as to ensure that none of your data is lost or corrupted during the process.

It is also crucial that you power off your laptop completely and disconnect it from any power sources externally, such as its charger prior to beginning the display replacement process.
