Fix problems with your Chromebook keyboard
If the volume or brightness keys don't work, you might be at the upper or lower limit for that setting.
If the backward or forward buttons don't work, check if the same icons in a web browser window are grayed out. For example, if the back button on a webpage is gray, the browser isn't aware of a page to move backward to.
If you have other problems with your keyboard, try these steps:
- Turn off the Chromebook, then back on.
- Delete the account that has the problem on your Chromebook, then add it again.
- Reset on your Chromebook hardware.
