Introduction

Once you remove the bottom casing and Ethernet PCB board, the audio and USB PCB board becomes accessible. Remember to pull on the power connector itself and not the wires to avoid damage.

If either the audio jack or USB type C connector are damaged, this guide will show you how to replace the board.

A Phillips #0 screwdriver can be used for both screws.
