Used Laptop Checkup
Follow a practical inspection checklist before buying or selling a second-hand laptop. Combine browser-based tests with the checks only a person can perform.
Run your test
Check a used laptop before buying with a free inspection checklist and links to camera, keyboard, microphone and screen tests.
Check each item after inspecting the device. This is a manual checklist: ticking a box means you confirmed it, not that DeviceDIY automatically tested it.
Start by checking the screen, keyboard and charging condition.
How to use this test
- Inspect the laptop in person and make sure you have permission to test it.
- Run the linked camera, microphone, screen, keyboard and speaker tools.
- Tick an item only after you personally verify it.
- Check charging, battery health, storage and ownership using operating-system tools and documents.
- Print or copy your checklist before making a purchasing decision.
What this can and cannot prove
The browser cannot determine whether a laptop is stolen, verify battery wear, certify internal components or guarantee long-term reliability. This checklist records what you inspected and is not a warranty or diagnostic certificate.
Compare results with your operating-system diagnostics or a second device when a fault is suspected.
Frequently asked questions
Can a website test every part of a used laptop?
No. Some checks require operating-system tools or physical inspection, and ownership cannot be verified from a webpage.
Is a completed checklist a certificate?
No. It only records checks that you personally marked as completed.
Can I save my checklist?
Yes. Use your browser print dialog to save a PDF or copy a short checklist summary locally.
