Asus Zenbook UX31A Daughterboard Replacement

Introduction

This guide will show how to replace the daughterboard on the Asus Zenbook UX31A laptop. This daughterboard contains the SD card slot, headphone jack, and USB port. This may be necessary if you are unable to connect external devices to your computer.

The connection card is responsible for allowing the computer to read and communicate with external hardware. If your card is having issues, the ports on the right side of your computer will not connect to external hardware.
