GEARCHECK LABWork through the visible condition and browser-accessible functions of a laptop before buying it. Record your own observations and save a local checklist.

No measurement yet.
A checked item means you observed the described function during this inspection; it is not a warranty or an automatic hardware verdict. Keep not-tested items visible rather than treating them as passes. Record the device model yourself and note whether tests were run on battery or mains power. Physical damage, hinge stiffness, missing screws and charger condition need direct inspection. Ask the owner to demonstrate charging, sleep/wake and the operating-system battery report. Check the receipt, ownership and any activation lock with the seller.
Web pages cannot inspect SSD SMART health, battery wear, internal temperatures, firmware locks or hidden damage. Do not enter passwords, serial numbers or personal documents into the notes. The checklist remains in this tab until you download it; it is not automatically saved.
Device previews, recordings, selected files and report notes stay in your browser. Downloaded files remain on your device. The call check sends small HTTP probes to GearCheck Lab. The WebRTC test exchanges temporary connection descriptions through our server and contacts the disclosed STUN service only after you create or join a session. Ordinary page requests and usage measurement are described in our privacy policy.
