Keyboard, mouse or trackpad not working
When the keyboard or mouse stops working, it's usually batteries, a loose plug, or a setting that got switched off by accident.
Be careful: If a drink was spilled on the keyboard, turn the computer off and unplug it right away, and don't turn it back on. See our spilled drink answer.
What to do
Step 1: For a wireless mouse or keyboard, change or charge the batteries and check its on/off switch.
Step 2: For a wired one, unplug it and plug it into a different USB port.
Step 3: Wipe the touchpad clean and dry.
Step 4: Restart the Chromebook. If you can't click, hold the power button until it turns off, then turn it back on.
Step 5: Open Settings, search for Touchpad or Mouse, and check the settings look normal.
Still stuck? If a plug-in USB mouse or keyboard works but the built-in one doesn't, contact the computer maker's support or a trusted repair shop.
