Chromebook

If the sound isn’t working on your Chromebook, check that both devices have the volume turned up if you are using an HDMI cord, try completing a hard reboot, be sure you are setting up an HDMI connection properly when connecting to a TV, and unplug headphones and reinsert headphones for recognition.

If your Chromebook isn’t turning on, be sure to remove any external devices that are connected to the computer, allow it ample time to charge before attempting to turn the device back on, and charge your device when it will not turn on and there is no light indicator illuminated.
