Hey guy's thank you all in advance. Ok this is fundemental I can't disable the mouse pad on my dell inspiron 5110 laptop so I can use my external usb mouse. I've tried different ways: uninstalled the mouse driver from the control panel under mouse properties It has no effect and it re-installs automatically when I re-start the laptop. Also tried to un-install from the device manager and it has no effect it re-installs. As well as from the devices and printers; and there is an fn key:f3 for this model to diable the mouse pad; it doesn't work at all. I was thinking of disconecting it but it probly won't pass post if I do that. Mabe the is a way to do it from the registry? Help please.
