I can't get my Chromebook to produce any sound. The volume is turned up to the highest setting, but it still won't work.

My Chromebook won't charge even when plugged into a power source.

Try pushing the power button and HOLD it for 7 seconds. The Chromebook will turn off. Wait 10 seconds and push the power button again to turn it back on. If this doesn't work, try disconnecting the charger and remove the battery for 1 minute then try again.
