Check your keyboard, camera, microphone, speakers, screen pixels, and battery — all in one place, free, right in your browser. Pick a tab below, or tap a test card to jump straight to it.
F1–F12 not lighting up? On many laptops they change brightness or volume. Hold Fn and press them again. The Fn key itself can't be detected by a browser.
Click "Start Camera Test" and allow camera access to check if your webcam is working.
Click "Start Mic Test" and speak normally — the bar should move as you talk.
Turn up your volume and test each speaker.
Pick a color, then click Full Screen. Look carefully for any dot or patch that doesn’t match — that’s a dead or stuck pixel.
White selected. Click "Full Screen" to begin.
In fullscreen: ← → cycle colours · 1–6 jump to colour · click or Esc to exit
Click below to read live battery data from your system.
Live data works in Chrome & Edge. Firefox and Safari don't share battery data.
The browser can only see the charge %. Your battery's real health (how much it holds compared to new) can be read by your computer itself — 3 quick steps:
You're on a phone or tablet. Battery health has to be checked on the laptop itself — open this page on your laptop.
powercfg /batteryreport /output "%USERPROFILE%\Desktop\battery-report.html"
The file is read in your browser only — nothing is uploaded.
Cycle count: hold Option, click the Apple menu → System Information → Power.

Move, click, right-click and scroll inside the box above to test all touchpad functions.
Click "Read Display Info" for instant specs, or "Measure Refresh Rate" for a 5-second precision test.
A quick way to confirm whether a problem is a hardware fault or just a settings issue — before you book a repair.
The key is most likely damaged inside — either from regular wear or a liquid spill. Bring it in and we'll check which key needs fixing.
It could be a privacy setting blocking the camera, or the camera itself may be damaged. We'll figure out which one in minutes.
The microphone may be blocked, broken, or muted in your sound settings. Either way, it's a quick thing for us to check.
The speaker is likely damaged — especially if the laptop was dropped or had a spill. Usually a straightforward replacement.
That spot on your screen is damaged — it's either permanently dark or stuck on one colour. The screen may need to be replaced.
The battery is likely worn out and needs to be replaced. If it won't charge at all, the charging port may also need a look.
Your keyboard (every key, plus a 15-inch laptop layout and a MacBook layout), your webcam, your microphone with playback, and your left and right speakers.
Usually yes, if you're sure you tried it properly. It could be wear and tear, damage from a drop, or a liquid spill affecting that part. Bring it in and we'll confirm the exact cause — no charge for diagnosis.
The keyboard test needs a physical keyboard, so it works best on a laptop. The camera, mic, and speaker tests will also work on a phone browser.
Yes, completely free, no sign-up needed. Everything runs directly in your browser — nothing you type, record, or preview is stored or sent anywhere.
The test fills your entire screen with a single solid colour — white, black, red, green, blue, or yellow. Any pixel that displays the wrong colour (or stays black or stays lit) stands out immediately. Cycle through all six colours for a thorough check, because a stuck pixel may only be visible against certain backgrounds.
The live charge level works in Chrome and Edge, not in Firefox or Safari. Battery health comes from a report Windows makes for you (one command, shown in the Battery tab) and works in any browser on a Windows laptop. Your battery information never leaves your device.
