Hi Szeejdi,

and a short video:

How to Fix Touchpad Problems on a Laptop

You can also run Dell SupportAssist to detect any hardware issues.  Make a note of any error messages encountered and post back.  Thanks.

I did BIOS update and diagnosis via SupportAssist and after pressing F12 and running Diagnostics there, both returned that there's no problem with my notebook, also i've tried what is described in link that you provided, but touchpad coursor is not smooth when moving still.

I have been searching for a solution in ages, and today I finally found a solution.

In my case, a Dell Latitude E5470, turning off gestures didn't help, but

1. Installing the latest driver as of today,
2. disabling the touchpad in BIOS,
3. booting into Windows,
4. enabling the touchpad in BIOS, and
5. booting into Windows again

fixed the issue.

No need to turn off the gestures. The issue will be resolved by installing 'Intel HID Event Filter' drivers. Refer to your computer support page on Dell website and download and install the driver.

Unfortunately, the driver does not get installed by Windows Updates; therefore, manual installation is necessary.

This applies to all Dell laptops.

I'm getting this problem on my E5570 even though the article doesn't mention my model. Tested in the BIOS as well - so it's not a software issue.

For me, the magic was to swap in a real Dell charger.  Problem only occurred for me when using an aftermarket charger.

Tried everything and the only thing that worked was using a genuine Dell AC Adapter.  Plugged in the incompatible one it froze, plugged in the genuine one and it worked!

This worked a charm! nothing else did. Thank you for sharing.

Bonjour,

Même problème. Pointeur de souris incontrôlable par moments.

J'ai tout essayé : pilote, mis à jour sur le site DELL, désactivation dans Alpsalpine, désactivation du périphérique touchpad (qui se réactive tout seul).

La seule chose qui a fonctionné, c'est de désactiver le touchpad dans le Bios. Je n'ai plus de touchpad mais avec une souris, ça marche.
