I'm not exactly sure the reason your touchpad isn't working, it may be a defective touchpad, but there is something probably not configured right in your settings. Try this: hit the windows button on your keyboard to pull up the start menu. Tab down to Settings and then key down to Mouse and touchpad. Use your keyboard controls to go down to the bottom and highlight "additional mouse options," then hit enter. Go over to hardware, then Highlight the ELAN input device. You should be able to hit the properties and then uninstall the drivers. I found that after the driver was uninstalled, and the computer restarted, the problem was fixed on my laptop. Hope that helps.
