简介

If your Lenovo ThinkPad W540 has a black, distorted, or a physically cracked screen, this guide should help you replace the display itself. Displays are important as they obviously show you what you are currently doing with the laptop. A faulty display will lead to a poor user experience to the user.

Note that this guide assumes that you have already checked that your video drivers are ok, and the display brightness is not on the lowest setting.
