Windows 10: Trackpad Cursor Shaking

Hey guys, just wondering what causes my cursor to shake on its own whenever I tried using touchpad. Anyone? help me fix this please. I did all to fix this but none of it works :

:)

 

Trackpad issue

I have a Dell 3515 laptop just bought last year but just after 1 month my laptop cursor is shaking and sometimes freezing it is so erratic I have replaced the trackpad also but the issue persist and it comes after every windows cumulative update so pls help me

 

Odd Trackpad Behaviour

Windows 10 ver 20H2. SONY VAIO laptop with Samsung 860 SSD, 4GB RAM.

Initially, the laptop worked fine. Recently an odd problem has surfaced.

I prefer to use a wireless mouse (Logitech V450 Nano) which behaves as expected. However, the laptop's own trackpad is (for want of a better word) is 'inverted'.

To explain: Move finger UP the trackpad (towards the keyboard) and the cursor moves DOWN. Move your finger RIGHT on the trackpad and the cursor moves LEFT.

Searches suggest changing some settings under Trackpad in Device Manager, however, looking in Device Manager there is no entry for Trackpad - only two entries for mouse: HID-compliant Mouse and PS/2 Compatible Mouse.

There are 3 possible trackpad entries in Human Interface Devices:
HID-compliant consumer control device
HID-compliant vendor-defined device
HID-compliant vendor-defined device
but delving into the properties of each, none seems to be for the trackpad.





In Settings > Devices there is no entry in Trackpad for inverting the trackpad





So, I'm rather stumped.

Any help gratefully received.

Mouse Cursor shaking

I have had trouble for ages with my mouse cursor shaking and moving when not required. I read up on all the possible solutions and tried them but nothing worked. In desperation I changed the battery in the mouse 'et Voila!!' all fixed!!
