yes i only want to use a external mouse usb plugin. but having my touchpad still active it effects my performance. example when i type sometimes just my wrist hovering over the touchpad makes my mouse go crazy and other stuff. i Just want to fully disable my mouse pad on the laptop and no my manual doesnt say how to disable it, it would usually be the fn key + f9 but that clearly doesnt work. ive done some research and that feature always works improperly. i have done other methods stated above but it doesnt pretain to me because my system doesnt show it...
again yes i am trying to disable the mouse pad on my laptop so i can only use the usb mouse without any interference
