TROUBLESHOOTING
Keyboard test FAQ
Practical answers without delaying the test.
A key does not light up. Is it broken?
Not necessarily. Try the key in another browser and application. Shortcuts, settings, drivers, wireless interference, debris or hardware damage can affect the result.
Can I test a laptop keyboard or numeric keypad?
Yes. Choose the physical form that matches your keyboard. The tester changes which positions count as required.
Why can’t KeyTest detect Fn or Power?
Many laptops process Fn, Power, brightness and some media keys before the browser receives them. Their absence here does not prove a fault.
Does KeyTest record what I type?
No. Testing happens in this browser; only your selected layout and keyboard form are saved locally.
KEYTEST
A complete online keyboard test
Press each physical key and KeyTest highlights it in real time. Switch between laptop, laptop + numpad, full-size, tenkeyless, 60 percent and Mac forms, including navigation keys and the numeric keypad.
Advanced mode helps inspect rollover, repeated input, possible chatter and keys that appear stuck. Testing runs locally in your browser; only your selected layout and keyboard form are remembered.
QUICK GUIDE
How to test your keyboard
- Choose the physical layout and keyboard form that match your device.
- Press each key once and watch the matching key highlight; the counter shows what remains.
- Repeat a missed or repeated key in Advanced mode before deciding that the hardware is faulty.
TROUBLESHOOTING
When a key does not respond
Try the same key in another browser and in a plain text editor. Browser shortcuts, operating-system settings, drivers, wireless interference and debris can affect a result; Fn, Power, brightness and some media keys may never reach JavaScript.
For a laptop keyboard test, external USB keyboard test or numpad test, select the matching form first. KeyTest reports browser keyboard events—it cannot replace a physical inspection or a complete switch diagnosis.
