Acer Chromebook CB3-431-C5EX Speaker Replacement

Difficulty

Moderate

Steps

Time Required

10 minutes

Introduction

This replacement guide will instruct you on how to replace the two internal speakers in your Chromebook. For this repair all you will need is a Phillips #0 screwdriver and a plastic spudger. Remember to completely power down your Chromebook before beginning this replacement, and always be gentle when handling the internal components of your computer as they are fragile.

Tools

Phillips #0 Screwdriver

Step 1

Working on your device while it is turned on may result in electric shock. Make sure to shut down and unplug your device before you begin.
Turn device over so the bottom panel is facing you.

Step 2

Remove the eight 4mm Phillips #0 screws.
Remove the two 6mm Phillips #0 screws.

There are two tabs on the battery opposite the connector side that need to be inserted into the retention slots or the battery won’t sit flat. Need to do this before reinserting the battery screws.

Also, I found that #00 Phillips works best on the 4mm screws.

Step 3

Insert a plastic opening tool into the crack between the bottom panel and the side of the computer.
Gently pry the panel off the computer by continuously pulling up and on the panel and moving the plastic opening tool around the crack until the panel comes off.
There are several clips holding the cover in place.
Remove the bottom panel and set it aside.

Step 4

Remove the two 4mm Phillips #0 screws securing the speaker.

Step 5

Remove the speaker from the computer.
Repeat the previous steps to remove the second speaker from the computer.
Note that the two speakers are connected by a wire, so you must replace both of them.
