The keys on the keyboard are unresponsive or missing altogether.
Full Keyboard Unresponsive
If you are using a separate keyboard USB/Wireless, make sure the keyboard is connected via USB/Bluetooth correctly. If it is connected properly and still doesn't respond, your computer may have software problems.

Chromebook Not Plugged In
Plug your Chromebook into the power outlet using the Chromebook's power cord. If your Chromebook is out of battery, the Chromebook will not be able to turn on and operate.
If plugging in the Chromebook does not cause the power light to turn on, then the problem may be a faulty battery. If this is the case, please refer to this guide in order to replace your battery.
The Chromebook is on but the mouse cursor does not move/respond to sliding on the touchpad.
First check if the mouse cursor on the Chromebook works and is not a result of the computer's software settings. Plug an external USB mouse into the Chromebook and check to see if the mouse cursor works/moves. If it doesn't move, then there is a problem with the computer mouse cursor settings.
If plugging in an external USB mouse into the Chromebook successfully works/moves the mouse cursor, then the touchpad is faulty. Please refer to this guide in order to replace your touchpad.

Check to make sure that the faulty audio is not due to the headphones themselves.
