I've had an intermittent problem with my laptop touchpad

It doesn't stop working completely, but after my laptop has been on and running for an hour or so this problem starts. When I first touch the pad the mouse cursor won't move for a couple of seconds. I have to keep my finger on the pad for about 2 seconds, and then the cursor moves. After I restart the problem goes away and cycle starts again, similarly if I log out and back in again it can solve the issue temporarily.

Pad clicks work fine, as does the touchscreen, but scrolling with two fingers does not.

I have reinstalled the driver. I've also tried using procexp to search for 'hook.dll' in case I could spot a program using it.

Recent changes are installing Windows 11 (in October, about a week before this started), and uninstalling Touchpad Blocker (a couple of days after this started to see if it was the problem).

Laptop is a Dell XPS 15 7590 purchased in June last year.

Can anyone suggest anything else I can try to diagnose this?

  • Have you tried adjusting touchpad sensitivity and setting for ignoring palm-touch (i.e., large area, rather than finger)? digitalcitizen.life/touchpad-settings-windows-11 Since this happens only after some time, it might be a gradual warming or dampening that causes the issue, rather than the OS alone.

  • @DrMoishePippik yes I've tried adjusting those settings to no avail. I'm convinced this isn't a hardware issue as logging out and in again fixes it (temporarily).

If the newest driver does not fix the issue, you need to contact Dell Support about the issue.

The machine should still be under warranty (9 months old).

There may be a compatibility issue with Windows 11 - should not be but this is also a question for Dell.
