So it doesn't work, or it does? I'm a bit confused here.
Normally Windows should automatically recognize your touchpad, but to make sure you can open "Device Manager" (an app in your system), go to "Mice and other pointing devices" to see whether a "TrackPoint Device" is there. If its not there, you can go to "Action" > "Scan for hardware changes". If the "TrackPoint Device" is still not there, then you should go to the manufacturer's website to install the corresponding driver(s) if needed. If that also doesn't work, then bring your laptop to the nearest IT service provider / laptop repair shop, there could be deeper issues involved.
Does the question have anything to do with .NET F# though?
