16 Plus DB16255, HELP Hover is possessed

So to confirm, the touchpad is randomly moving the mouse/ its not responding correctly? Should this be the case, I would recommend trying to replicate the issue within the BIOS. If the touchpad is not responding correctly here, then your issue is hardware and you should contact support for a warranty repair. 

1. Restart the unit
2. Constantly tap the F2 key when the dell logo appears to enter the BIOS
3. Move the touchpad around to see if it responds correctly

The only other thing to try out should it not respond correctly in the BIOS is a hard reset. 

1. Disconnect any external devices including the AC adapter and disconnect the battery cable if able.
2. Hold the power button down for 10 seconds 
3. Bypass any power strips, surge protectors or battery backups
4. Verify the wall outlet is functional
5. Reseat the battery cable if disconnected
6. Plug only the AC adapter back into the laptop
7. Attempt to power on the system
