If your Chromebook is in tablet mode, press the volume up or volume down button to take a picture.
An indicator light next to the camera will turn on if that camera is active, so you can figure out if your external camera or your built-in camera is currently in use. If your webcam is not appearing to work with your Chromebook (it doesn’t appear as an option when you plug it in), you might not have a compatible webcam. In that case, check the webcam’s manual for Chromebook compatibility. If you open the Camera app and see the message, “No camera found,” try restarting your Chromebook, then using the camera in another app, like Hangouts or Skype. If the camera still doesn’t work, try resetting your Chromebook to factory settings. If the issue persists, the hardware may be damaged and you’ll need to talk to the Chromebook’s manufacturer.
