Lenovo 100e Chromebook Gen 4 Screen Replacement

Introduction

Use this guide if the screen on your Lenovo 100e Chromebook Gen 4 is malfunctioning or broken. The LCD screen is responsible for outputting all visual elements on your Chromebook. If your Chromebook produces sounds through the speaker but the screen remains black, or if the laptop powers on and off but the screen remains black, or if the touch capability of the screen isn't working, or if there is any visible damage to the screen, the screen may need replacing.

Check our troubleshooting guide for possible solutions before deciding to replace.

This guide requires handling the internal parts of the Chromebook, so usage of an anti-static mat and anti-static wrist strap is recommended.

Unplug all cables and ensure the laptop is powered off before beginning.
