Laptop Health Check
Run a complete hardware check on any laptop right in your browser. ProbeCheck tests the screen, keyboard, webcam, microphone, speakers, and trackpad so you can verify everything works.
Frequently Asked Questions
What does the laptop health check test?
It tests six hardware components in sequence: screen (resolution, dead pixels), keyboard (all keys, stuck keys), webcam, microphone, speakers, and mouse/trackpad.
Can I use this to verify a laptop before buying?
Yes. Run the check on the laptop you are considering. The result summary shows which components passed and which have issues, helping you make an informed decision.
Can I save or share the results?
Yes. After the check completes, you can save the results locally and share a summary.
Does this replace a professional inspection?
ProbeCheck tests what browsers can access. It cannot check internal components like battery health, storage speed, or CPU thermals. For a complete inspection, combine browser tests with system diagnostics.
