Windows 10: Laptop Trackpad saying device deleted on Device Manager

For around 3-4 months now the trackpad on my laptop has not been working. Occasionally it would work for around 10-15 seconds after it restart the laptop but not anything other than that. When I go into device properties it says "Currently, this hardware device is not connected to the computer. Code 45". In the events it says that the device was deleted but then around a week later it was configured and restarted.

No hardware listed in Device manager?

I don't konw whathappend but in Device manager and in my Network connections there is nothing where there used to be a Modem listed and all my hardware in Device Manager. What happend and how do I fix this?

 

Network devices listed under Unknown in Device Manager


I have a Dell Inspiron M731R laptop upgraded from Windows 8.1 to Windows 10 Home 64-Bit that suddenly quit connecting to the home network. Was using wireless, so switched to an Ethernet cable, but still no luck. I just discovered that ALL of the network-related devices are now listed under an "Unknown" tab in the Device Manager. A check of properties of each item in that folder says they are all working properly, but that obviously isn't the case. I tried uninstalling each of the 4 items, but when they are recognized again they still show up under the Unknown tab. Any suggestions would be welcome.

 

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.
