Touchpad observation test
Observe pointer movement, clicks and vertical or horizontal scrolling from your touchpad.
Diagnostic visuals retain their original colors and remain visible. Presentation filters and high contrast apply outside this workspace; device-level filters may still affect your observation.
Use only your touchpad in the pad. Move, click, scroll vertically and horizontally, then save.

Understand the result
PASS describes a received signal or your recorded observation. WARNING calls for another check. USER REVIEW REQUIRED means a measurement alone cannot decide. An unavailable API or denied permission does not establish hardware failure.
What this cannot tell you
Browsers usually cannot distinguish a mouse from a touchpad. OS gestures may never reach the page.
If something seems wrong
Check touchpad settings and gestures in your OS, clean the surface and repeat.

Is anything uploaded?
Raw diagnostic input and media are processed locally. Standalone results remain in page memory. Guided checks offer optional coarse session recovery for 24 hours; it excludes media and detailed measurements. Hosting and Google Analytics requests still leave your browser. Analytics receives only broad test-usage categories, never these diagnostic contents. See the privacy policy.
Does a pass guarantee my hardware is healthy?
No. It records behavior observed in this browser session. Intermittent faults, internal components and operating-system restrictions need further investigation. See our methodology.
