Laptop Lab: Zero-Install Browser Hardware Diagnostics

说明与用途

Laptop Lab 是一个单页 Web 应用，允许用户在不安装软件、也不将数据发送到外部的情况下快速测试显示器、摄像头、麦克风、键盘、触控板、扬声器和电池。

问题

Users need a quick, privacy‑preserving way to test laptop hardware components without installing software.

结果

All tested components (display, camera, mic, keyboard, touchpad, speakers, battery) can be evaluated instantly in the browser with no external data transmission.

工作流

• Open https://lokilancer.github.io/Laptop-Lab/ in a supported browser over HTTPS
• Allow camera and microphone access when prompted
• Run each test by clicking its button: display, camera, microphone, keyboard, touchpad, speakers, battery
• Review results displayed on the page; thresholds stored in localStorage for repeatability

证据

I built Laptop Lab — a single-page web app that tests your laptop's display, camera, mic, keyboard, touchpad, speakers and battery. No install, no dependencies, no data leaves your machine.
