Introduction
Use this guide to replace the display assembly (aka screen) on your HP EliteBook 840 Aero G8 laptop.
The display assembly includes the display panel, top shell, bezel, hinges, sensors, and camera. This guide does not cover removing the display panel on its own. Click here for that in-depth guide.
If your display is broken, cracked, or has dead pixels, it may be time to replace the display assembly.

Use tweezers to hold a connector in place over its socket and gently press down with your finger or a spudger—the connector should "snap" into place. If you're having trouble, reposition the head and try again. Don't use excessive force.
