Introduction

The motherboard is behind the functionality of your device’s touchscreen and USB port. A broken motherboard could result in issues with either your touchscreen or USB port. Since the USB port is connected to the motherboard, you may have to review the iFixIt Soldering guide (How To Solder and Desolder Connections).

This guide was created with a model PTK-640 Wacom Intuos4. Different models may vary in design.
