Razer Blade 2014 Disable Touchpad When USB Mouse Plugged In

So just a few days ago I received the 2014 Razer Blade as a Christmas gift from my wife and I am one very luck man, one thing that I noticed after using it a few minutes is that the USB mouse when plugged in doesn’t disable the trackpad so while I was trying to use the keyboard my thumbs kept moving the mouse cursor and clicking on stuff.

I checked in my mouse settings in the control panel, but there was no specific option to disable touchpad when USB mouse detected.  Well a quick search on Google and I found some steps how to accomplish this and found it was common in the Razer Blade 2014 so figured I would repost here with more detailed screenshots.

So the first thing you want to do is see if your mouse settings have the option to disable trackpad with USB mouse detected.  The actual parameter is called Disable internal pointing device when external USB device is attached.

If you don’t have this option, your screenshot will look like below (you will not see this option at all in your mouse settings under devices)

 

So then you just need to follow these steps to add Disable Internal Pointing Device to Mouse Settings.

Open regedit (it will prompt you and click yes)

• Navigate down to and expand HKEY_LOCAL_MACHINE
• Navigate down to and expand SOFTWARE
• Navigate down to and expand Synaptics
• Click on the SynTPEnh folder
• Then on the right right click and Click on New
• Then click on DWORD (32-bit) Value
• Now rename this New Value #1 to DisableIntPDFeature

• Double Click on it
• Give it a value of 33 (make sure the hexadecimal is selected, it should be by default)

 

• Click OK

You may also have to put the same registry setting in your HKEY_CURRENT_USER and it is recommended you do this by default. Just make sure you are still in regedit or open regedit again.

• Open the HKEY_CURRENT_USER
• Open the SOFTWARE folder
• Open the Synaptics Folder
• Click on the SynTPEnh folder

• Then on the right right click and Click on New
• Then click on DWORD (32-bit) Value
• Now rename this New Value #1 to DisableIntPDFeature

• Double Click on it
• Give it a value of 33 (make sure the hexadecimal is selected, it should be by default)

• Click OK

After this you now should see the Disable internal pointing device when external USB pointing device is attached show up under your mouse settings, under the Device Settings tab.

Note though I did this for the Razer Blade this tip should work for any laptop or notebook that uses Synaptics touchpads if they don’t have this option listed by default.  This seemed to be a fairly easy and flawless way to disable touchpad on laptops that didn’t have this function as an option in their mouse settings.

Also found on a notebook forum here: http://forum.notebookreview.com/razer/753243-2014-blade-touchpad-disable-usb-fix.html that on the Razer Blade 2014 someone had to also disable the HiD compliant mouse as an additional step, but I did not have to do this on my Razer Blade 2014 so I didn’t include that as a standard step.
