Touchpad test
Check every part of your laptop touchpad — clicks, two-finger scrolling, pinch to zoom, dragging and smooth pointer movement — and spot unwanted double clicks and sudden pointer jumps.
How to use it
- Unplug any external mouse first — to a browser, a mouse and a touchpad look the same.
- Move the pointer slowly inside the box from edge to edge, then in fast circles. The trail should be smooth; sudden jumps are drawn in red.
- Work through the list: tap and press to click, two-finger tap for right click, two fingers to scroll both ways, pinch, and one long drag. Each step turns green when the browser has seen it.
What the warnings mean
- Unwanted double clicks: one press arrived as two within 70 ms — faster than any finger can click. A worn or bouncing click mechanism is the usual cause; a too-sensitive tap-to-click setting is the other.
- Sudden pointer jumps: the pointer leaps while your finger moves steadily. Common causes are dirt or moisture on the pad, electrical noise from a charger (try unplugging it), and outdated touchpad drivers.
- Drag breaks off: the press let go in the middle of a drag. That points to a weak click button, or to the "tap and drag" settings of your system.
Check by hand
- Three- and four-finger gestures (switch apps, show the desktop): they are handled by your system and never reach a web page, so try them yourself.
- Palm rejection: type a few sentences in a text editor; the cursor shouldn't jump when your palm touches the pad.
- Even clicking: press the pad in all four corners and the middle. On most touchpads the top edge is meant to be stiffer — but every spot should give a clean click.
What a browser can't see
A tap and a physical press arrive as the same click, so the test checks that both work instead of telling them apart. A web page also doesn't know where your finger is on the pad, only where the pointer goes — so it can't draw a map of dead zones. Move the pointer across the whole screen and watch for spots where it stops.
Frequently asked questions
Scrolling or pinch doesn't react at all
Check the touchpad settings: on Windows under Settings → Bluetooth & devices → Touchpad, on a Mac under System Settings → Trackpad. Some older laptops need the maker's touchpad driver for gestures to work.
The pointer only jumps while the laptop is charging
That is usually electrical noise from the charger or the wall socket. Try another socket, the original charger, or touch a metal part of the laptop: if the jumps stop, the touchpad itself is fine.
Is anything recorded?
No. The test only reacts to events inside the box on this page; nothing is stored or sent.
