Introduction

The built-in speakers can produce audio without the need to plug in any additional devices.

Before using this guide, make sure nothing is plugged into the headphone jack and that the volume of both the computer and the media being played is at a high value. You can troubleshoot audio problems by right clicking the sound icon in the taskbar and selecting “Troubleshoot sound problems”. Try playing different types of media from different sources.

The speakers in this system are wired together so they are not individually replaceable but must be replaced as a pair.

Before beginning, make sure to power off your laptop completely and disconnect from any external power source.
