Lenovo ThinkPad T470 TrackPad Replacement

Introduction

Use this guide to replace the TrackPad in your Lenovo ThinkPad T470.

The TrackPad (also known as a touchpad) translates finger gestures, such as swiping and clicking, to computer actions like dragging and scrolling, similar to how a mouse functions. If the TrackPad is not responding to any gestures or if your gestures are behaving erratically, your TrackPad may be faulty. Before attempting to replace the TrackPad, visit Lenovo’s troubleshooting manual for diagnosing TrackPad-related issues.

If you need to perform a replacement, make sure to disable the internal battery, power down your device, and disconnect from any external power sources before you begin.
