How these keyboard and mouse tests work

An online keyboard test registers each keypress so you can spot stuck, unresponsive, or double-firing keys. Choose a layout that matches your keyboard, full-size, TKL, 75%, 65%, 60%, or smaller form factors, then press every key once until the progress bar is complete.

The mouse test checks three common failure points: click-and-drag, click accuracy on targets, and continuous scroll-wheel input. Run each step in sequence and mark the result pass or fail when you finish.

If a key or mouse input fails here, try another USB port or a different device to see whether the issue is the peripheral, the connection, or the computer itself.
