We've put together a set of simple, no-install tools that both regular users and repair technicians find useful. The camera test helps you figure out why you're invisible on a video call. The microphone test shows the actual signal level in real time. The battery test tells you whether your laptop's battery is still healthy or if it's time for a service visit. All tools work without registration or any software installation — just open and check. Your data is never sent to our servers; everything is processed locally in your browser. If a test reveals a fault, contact NextRepair — we'll run a full hardware diagnostic and carry out the repair.
