Laptop Lab: Zero-Install Browser Hardware Diagnostics

Описание и применение

Laptop Lab – это одностраничное веб‑приложение, которое позволяет быстро проверить дисплей, камеру, микрофон, клавиатуру, тачпад, динамики и батарею ноутбука без установки и передачи данных за пределы устройства.

Задача

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

Результат

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

Рабочий процесс

• 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

Доказательства

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.
