ASUS VivoBook S400C LED Board Replacement

Introduction

It is rare for LED boards to fail, so be sure to check that the function that is supposed to be lighting the LED is working correctly before suspecting a faulty LED.

Note that the battery has been removed for the purpose of visual clarity in this guide, but it is not necessary in order to replace the LED board. Doing so does make removing the ribbon cable slightly easier.
