There is a very easy way to disable the touchpad on your Windows 10 laptop when you connect a mouse, thus preventing any annoying touch with this surface when you use the mouse, something that you will surely want to do if this has ever happened to you.
Generally, when we connect a mouse to the laptop, the touchpad continues to work and that can cause a problem at certain times because a slight touch with such a surface it means that the cursor moves too, something that can be annoying.
This is precisely why in the vast majority of Windows 10 laptops there is an option that allows you to disable the touchpad from the touchpad itself moment in which the system detects that the user has connected a mouse via USB, so only use the mouse to move.
However, some Asus laptops and others make use of a specific app for the touchpad and that is how it exists a parameter that disables it when detecting a connected mouse. Therefore, this procedure can be performed in several ways.
From Windows 10
Through the operating system itself there is the possibility of deactivating the touchpad when connecting a mouse. It is possible that this possibility does not appear to you, but we are going to show it to you just in case if you have it available, you must perform the following steps:
- Press the Windows key combination + Q and type in the box “ settings”.
- Within configuration, access the section “devices”.
- Now go to “Touch panel” and finally, you must uncheck the box called “let enabled touchpad when a mouse is connected”.

Unchecking that checkbox does Windows is it disables the touchpad and leaves it inoperative while a mouse is connected, from the moment the mouse is detected to be disconnected, the touchpad automatically works perfectly again.
Using Asus Smart Gesture
If you have an Asus laptop, it is most likely that the option that we told you to disable in the previous method will not appear, but it does not mean that you cannot disable the touchpad when detecting a mouse, what happens is that Asus uses a specific software for this.
It's called Asus Smart Gesture and it controls everything related to the touchpad and mouse, in fact, it even enables an icon next to the clock where you can see that your touchpad appears in drawing and the keystrokes you are making, as well as how they are (short or long).
You have to click on that icon to enter Asus Smart Gesture and then follow these steps:
- Once inside the software, go to the “mouse detection” tab, there uncheck the box “disable the touchpad when mouse is connected”.

What this feature will do is the same as the first method we showed you, it will disable the touchpad when the software detects that there is a connected mouse. You can check it yourself to see if it works, so don't worry about that.
Other options
If none of the above possibilities work for you, you can try something else. In the same configuration window/devices/Touch panel enter the option that says “additional options”, “additional configuration” or similar that you will see on the right.
From here on the interface will depend on each manufacturer, it may be a Synaptics touchpad, so you may have a checkbox called “disable the internal pointing device when connecting an external USB pointing device” or similar that you will have to check.

Once this is done, and after clicking OK, you will probably have to restart the computer for the change to take effect. With these steps you will have configured your touchpad so that it is disabled when connecting a mouse in Windows 10, thus avoiding problems when having both devices connected at the same time.
