1. Go to the Control Panel. Under the 鈥楬ardware and Sound鈥?options, click 鈥楳ouse鈥?br>
2. Since you have a Dell laptop, you鈥檒l have a special tab called 鈥楧ell touchpad鈥?in the window that pops up. Click on the touchpad picture in the window.
3. In the new window that appears, click 鈥楧evice Select鈥?br>
4. Click on the 鈥楧isable鈥?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 鈥楧isable Touchpad/Pointing Stick when external USB mouse is present鈥?br>
That鈥檚 it. You鈥檝e disabled your laptop鈥檚 touchpad for good. If you don鈥檛 find an option to manage your touchpad in Mouse settings, you have to install Synaptics drivers.
