Hi @Marius - Roma ,
I would suggest you to check the HP (Hewlett Packard) models of your laptops in use, and search for any touchpad manuals/documentations available from HP. I believe this is the best way of getting any kind of manuals/guides, directly from the vendor/manufacturer.

If you're using the Windows 10 operating systems you can follow the touchpad gesture manual over here:
