Lenovo IdeaPad S340-15IWL Screen Replacement

Introduction

Use this guide to replace the screen on a Lenovo IdeaPad S340-15IWL laptop.

If your screen fails to turn on, is not displaying images properly, or has been cracked or busted, it may indicate that the screen needs to be replaced.

Make sure you read the troubleshooting page before beginning the replacement as there is a possibility that your device is not charged or that the issue can be resolved without disassembling the device.

Ensure that there is no food or liquid nearby as the device’s internal components will be exposed.

    • Carefully unwind the black cable that runs between the top of the battery and the bottom of the fan from the grooves along the side of the fan.

    • In order to do so, you will need to pull up the metallic tape that holds the cable in place using either your fingers or a plastic prying tool to lift up the edge.

    • If you attempt to remove the device’s fan without removing the battery, the black cable may be wedged underneath the top of the battery. In this scenario, it is recommended that you at least loosen the screws holding the battery in place to allow for the cable to be removed with less resistance.
