Practical device checks in the browser
LaptopProof provides lightweight tools for checking everyday laptop and peripheral functions without requiring software installation. Our goal is to make second-hand device screening and basic troubleshooting easier.
What our tools can and cannot do
Browser tests can confirm inputs, permissions, screen properties and some device capabilities. They cannot fully diagnose internal hardware, battery wear, storage health, firmware locks or predict future failures.
Privacy-first approach
Camera and microphone previews are processed locally by the browser for our built-in tests. We do not require an account to use the core tools.
