Welcome to HP Community!

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.
