Go to the Control Panel. Under the 'Hardware and Sound' options, click 'Mouse'
Since you have a Dell laptop, you'll have a special tab called 'Dell
touchpad' in the window that pops up. Click on the touchpad picture in
the window.
In the new window that appears, click 'Device Select'
Click on the 'Disable' radio button to disable the touchpad completely.
If you want to disable the touchpad of your Dell laptop only when an
external device like a mouse is attached, check the last option that
says 'Disable Touchpad/Pointing Stick when external USB mouse is
present'
That's it. You've disabled your laptop's touchpad for good. If you don't
find an option to manage your touchpad in Mouse settings, you have to
install Synaptics drivers from
here.
Similar options can be found in other laptops as well.
Good luck ! if your problem is solved don't forget to rate
