Try using the camera in another app. If it works in that app, try closing and restarting the original app where the camera doesn’t work and install it again. If the webcam still does not work, try uninstalling and reinstalling the original app. Apps can be removed from the apps list.

Log out of the Chromebook and sign in as Guest. Open Chrome and go to a website that uses webcam, like Skype. If the webcam works, it is a software conflict issue.

The outlet that is currently being used could be faulty. Use a different outlet to ensure it is not a hardware issue. Check the power cord for any damage to the wire. If there are internal metal wires that are visible or the wire is frayed at any point, the problem could be the charger.

If liquid is spilled into the keyboard, the keyboard components should be cleaned and dried as soon as possible, and as thoroughly as possible. Remove the keycaps using a keycap remover or another tool that fits (small flathead screwdriver, tweezers, etc.).

Afterwards, the keyboard should be left to dry as needed.

Sound should be playing from the Chromebook but is either muted, too quiet, or garbled.

If there is no sound, check that the system is not muted. Go to the volume settings in the Status Panel found in the lower right corner. If the settings are in order, check the settings of the source of the sound. Youtube videos, iTunes, and other media sources often have their own volume control. Double check that all settings are not muted or turned down.

If you are using headphones or external speakers to play the sound, check that they are fully connected. An icon in the Status Panel, on the lower right corner of the screen, will indicate where the Chromebook is attempting to play sound from, either its own speakers, headphones (or any device connected via the headphone jack), or Bluetooth. If your device is not connected, be sure that it is plugged in all the way. If it is a Bluetooth device, try reconnecting it.

Occasionally the Chromebook will experience a software malfunction, which can result in the loss of sound capabilities. Reset your Chromebook by turning it completely off, then pressing the Refresh Key (found at the top of the keyboard) and the Power button simultaneously.

If the speakers in your Chromebook are no longer functioning properly, they can be replaced. See our guide for replacing the speakers.
