Hi@Patravane, Welcome to the HP Support Community!
This is a wonderful location to converse with the community, get assistance and find tips! I understand you are having issues with the cursor moves on its own on your HP Notebook. Don't worry as I have a few suggestions which should help you resolve this issue.
To provide you with an accurate solution, I'll need a few more details:
Did this happen after a recent software update?
Have you tried to connect an external mouse and check if it works?
Have you checked if the cursor moves even in the Bios?
In the meantime, let's try these steps here: Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

The next thing, I would suggest here is to boot the computer into the Bios screen and check if the cursor moves on its own or not, If the cursor keeps moving on its own even in the Bios, then it's a possible hardware failure. If the cursor does not move on the Bios, then it's likely a software or driver issue, then you can try to update the Bios, graphics card drivers as well as touchpad drivers on your PC from our HP support website, using this link.
Once done, restart the computer and check if that works.
If the issue persists, let's try to check the settings:
Check the Mouse options under the control panel:
Start → Control Panel → Mouse → Buttons tab.
Check the box labeled "Use MS Office compatible scroll only."
Also, check the box below labeled "Scroll inactive window only."
If the issue persists, attempt the below steps:
Attempt using an alternate/external mouse.
(If that works when the touchpad is disabled on Synaptic software, it would mean that it's a touchpad failure,
However, if the external mouse doesn't work either, it could be a software/driver issue).
Uninstall and reinstall the drivers for your mouse:
Go to the Device Manager and select your mouse. Uninstall it and then restart your computer. During restart, your mouse driver will automatically be reinstalled.
1. Click on Start and type ‘Device Manager’.
2. Click Device Manager.
3. Click + sign next to Mouse.
4. Right-click on mouse entry and choose "uninstall".
5. Restart your computer.
