Alan, Here is how you could turn off the touch pad through windows settings. Also, note that this version of HP Pavilion's sometimes have driver issues that cause this feature not to be applied. In turn a driver update would help fix that and allow you to disable the touchpad.

Windows Settings:

1) Click Start - Control Panel - Mouse - Tapping - UnCheck the 'Tapping' Box - Then Click "Okay"

Windows Drivers:

1) HP Driver Page, but you will note there are several model listed.

2) Select the one that matches your system that on the bottom of your laptop. It should have a more specific model to choose from.

3) Select Your Operating System

4) Under the Category of "Driver - Keyboard, Mouse and Input Devices" download the "Touchpad Point Device Driver".

5) Follow the install instructions, and it maybe self installing. (A system restart maybe needed)

I hope that address your question, and best of luck to you!
