Device test

This device test checks several parts of a laptop or other device in one place. It tests the microphone, camera, speakers and screen, then checks for a connected controller. The page runs each test in a row, so you can see the results together in one report.

Each test can be skipped. For example, you can skip a camera check if your device has no camera, or skip a controller check if you do not use one. The report shows a verdict and key readings for each device that was tested.

The report gives each device a verdict and its key numbers. Read the verdict as the test’s summary of that device’s check. The numbers provide more detail about what the test measured, but the report does not set a universal pass level for every device.

For the microphone, the page listens and measures how loud the sound is. A low or missing reading can mean the test did not pick up sound; check that the microphone is connected and that sound is reaching it. For the camera, the test checks whether it can show an image. If no image appears, the camera may be unavailable or the page may not have access to it.

The speaker check plays sound and measures its level. If the reading is missing or you cannot hear the sound, check that the speakers are connected and turned on. The screen check shows a visual test, so look for whether its patterns and colors appear as expected. The controller check looks for a connected controller; no result may mean none is connected or detected. These checks do not measure whether your device is suitable for every task.

A bad verdict or missing reading means that part of the test did not return the expected result. It can point to a disconnected device, a device that is unavailable, or a test that could not access or measure it. It does not identify the exact cause.

Check the device connection, make sure it is switched on, and try the test again. If the same result remains, check whether the device itself works outside this page or use another way to test that device.

After the checks, the page puts the verdicts and key numbers into a one-page report. You can share the report with a link. The link carries the result in its address, and it does not include device names unless you choose to include them.

A shared report opens with a “run yours” option on the first screen, so another visitor can start their own test. You can also save the report as an image. The page draws that image in your browser.
