How to use the Chromebook keyboard test
- Open this page on the Chromebook you want to test.
- Press every key once — each one turns green when it registers.
- Hold a key to confirm it repeats, and release to confirm it clears.
- Test the modifiers (Shift, Ctrl, Alt) and the Search key.
- Note any key that never lights up — that's a dead or stuck key.
What the results mean
- Key turns green: the key works and is registering correctly.
- Key never lights up: a dead or disconnected key — likely hardware.
- Key stays green after release: a stuck key; clean under it or check for debris.
- Wrong character appears: a layout mismatch — check Settings → Device → Keyboard.
If keys still don't work
A key that fails this test is almost always hardware or driver related, not a website issue. Try these before assuming the keyboard is broken:
- Restart the Chromebook (a stuck Chrome OS process can block input) and retest.
- Sign in as a different user or use Guest mode to rule out a profile setting.
- Check Settings → Device → Keyboard for remapped keys (Search, Ctrl, Alt).
- Clean under the key with compressed air; check for trapped debris.
- Try an external USB keyboard — if that works, the built-in keyboard needs service.

Frequently Asked Questions
How do I test my Chromebook keyboard?
Open this page on your Chromebook and press each key. Every key you press turns green in the on-screen keyboard, so you can instantly see which keys register and which are dead or stuck. Work across all rows, then test modifiers (Shift, Ctrl, Alt) and the Search key. No download or sign-in is needed.
Does this test the Search key and the top-row keys?
Yes. The Chromebook layout shows the Search/Launcher key (where Caps Lock sits on other laptops) and the browser/system top row — Back, Forward, Reload, Full screen, Windows overview, brightness and volume. These light up on most Chromebooks; a few models report the top row differently, but letters, numbers, arrows and modifier keys always work.
How do I test a school or managed Chromebook keyboard?
The test runs entirely in the browser, so it works on managed and school (admin-enrolled) Chromebooks without any install or special permissions. Just open the page and start pressing keys. If a key does not respond here, it is a hardware or driver issue rather than a website or account restriction.
Some keys are not registering — what should I do?
If a key never turns green, first restart the Chromebook and retest, as a stuck Chrome OS process can block input. Then check Settings → Device → Keyboard for remapped keys, and clean under the key with compressed air. If it still fails on this test, the key or keyboard hardware is faulty.
Do I need to install anything?
No. This is a browser-based online keyboard test. Nothing is installed, and nothing you type is recorded or sent anywhere — key detection happens locally on your device.
