How this test works
Press keys and confirm that your keyboard responds correctly. The test uses standard browser capabilities and does not require installing an application.
When to use it
- Before buying a used or refurbished laptop.
- When troubleshooting a device after a repair or update.
- Before selling or handing a device to someone else.
Important limitations
A website cannot fully diagnose every hardware component. Treat the result as a practical screening check. For faults that matter financially or affect safety, use operating-system diagnostics or a qualified repair technician.
