Mouse Inoperable

I have an older Dell Latitude E6510 laptop, all of a sudden the touchpad mouse does not work, have to use a wireless mouse. Using Win. 10. Any help appreciated.

Also did you consider that that being that old the touchpad has failed. If this didn’t come with Win10 that could also be a driver problem.

WIndows 10 did a great job at finding all the correct drives on my ancient Toshiba A300-1MT laptop, so I would say that drivers want be an issue, probably its dead or it could have been disabled using the FN keys?
