If you have an external mouse connected to your laptop PC, turning off the laptop's mouse and/ or touchpad can help you avoid much frustration. Disabling the mouse and touchpad may sound like a daunting task, but it's not. You can easily toggle your laptop's mouse on and off without worrying about causing any damage to your computer.
Click on the "Start" button, then select "Control Panel."
Select "Classic View" to the left if you're not already there, then double-click "Device Manager." Hit "Continue" when asked if you want to launch the "Microsoft Management Console."
Click the "+" sign next to "Mice and other pointing devices" and find the laptop mouse and/or touchpad.
Right-click on your laptop's mouse and/or touchpad and select "Disable." Select "Yes" when asked if you really want to stop it. Your laptop mouse is now shut off.
To turn the mouse and/or touchpad back on, repeat Step 4 and click "Enable."
