Introduction
If you've tried the troubleshooting and your speakers still do not work, you may need to replace your speakers. This may be necessary if the speakers are old, or if they have been damaged. Speakers can be easily damaged if they come into contact with liquids. Be careful when replacing your own devices speaker, that you keep all parts away from harmful substances.

Using the iFixit plastic opening tool, wedge it into the seam of the bottom plate. This will create a small gap between the sections that you can gently pry open. Work your way around to each side of the device until the bottom pops free.

Once you have pried enough space between the Chromebook and the bottom plate, flip it back over so the bottom plate is facing you and gently pull it up with your hands.

Before you completely pull off the back, you must disconnect the MB cord.

Using blunt-nosed tweezers, carefully flip the black bar that keeps the MB cord latched in as circled in the image.
