HP EliteBook 840 G4 Trackpad Replacement

Introduction

If your HP EliteBook 840 G4’s trackpad isn’t clicking, moving the cursor, or is acting erratically, then the issue could be with the trackpad module or its internal connection.

The trackpad is responsible for translating your finger movements into input, and if its ribbon cable becomes loose or the board is damaged, the device won’t respond properly.

A good way to test this is to remove the bottom cover, check the trackpad ribbon cable, and reseat it firmly.

If it still doesn't work, you may need to replace the trackpad entirely. Use this guide to inspect or replace the trackpad.

Recycle any damaged parts at an electronic waste facility.
