Identify the laptop you are checking

Add a model or seller reference so it appears on your final report. Nothing is uploaded.

Step 1 of 8

Device details & physical condition

First confirm the laptop matches the seller's description and inspect the parts a browser cannot see.

Why this mattersBrowser tests can check functions, but only you can verify the physical condition and advertised model.

What the full LaptopProof test checks

The guided test combines browser measurements with clear manual checks so you can inspect a second-hand laptop without bouncing between separate pages. Individual tools remain available for deeper testing and search visitors, but the main buying workflow stays in one session.

Built-in

Interactive tests

Dead pixels, keyboard, pointer, webcam, microphone, speakers and browser-exposed device details.

Guided

Manual checks

Physical condition, battery swelling, ports, charger, ownership locks and seller claims.

Clear

One final report

Your pass, attention and skipped results are combined into a printable summary stored locally in your browser.

Frequently asked questions

Will the full test open a new page for every check?

No. The essential checks are integrated into this guided page. Separate tool pages still exist if you want to run a specific test independently.

Does LaptopProof upload my camera or microphone?

The built-in camera preview and microphone meter use browser media APIs and are designed to run locally in your browser. Permission is requested only when you start those tests.

Can a browser fully test SSD, RAM and battery health?

No. Browser security limits access to many internal hardware metrics. The final report clearly separates browser checks from items that should be verified using the operating system or manufacturer diagnostics.
