Which test for which problem?
| Problem | Start with |
|---|---|
| Others can't see me in Teams / Zoom | Webcam test - if it is black here too, check the camera privacy switch or F-key, then the camera cable. |
| People can't hear me | Mic test - no level at all points to the mic, its cable or a disabled driver. |
| Sound only on one side, or crackling | Speaker test - left/right and the tone sweep. |
| Some keys type nothing or type twice | Keyboard tester - often liquid damage or a worn keyboard ribbon. |
| Spots, lines or bright edges on the screen | Dead pixel test. |
| Clicks or scrolling don't work | Mouse & touchpad test. |
