How do I disable my touchpad on my Toshiba Portege 700?

The touchpad might have been disabled. try the Fn-F9 key combination. It toggles the touchpad ON or OFF.

Here -->link.

Download the touch pad driver from the manufacturer's website.

Perform a complete power drain

Disable the mouse device from device manager and enable it.

This will work

Most pc's use a program named symnaptics touch pad. Go to the control panel, select the mouse tab then mouse properties and device settings (select disable). Here you can disable the touch pad. I would recommend you have a usb mouse up and running prior to doing this procedure (saves tons of headache).

First , try letting "Windows Update" install new driver. Be sure to plug in any USB devices you want to use BEFORE you start Windows Update. That way ,Windows Update will detect these USB devices as well as your USB hub. Because it may be that your external USB device is the problem.

in my opinon. you should be re instal this touch pad driver.

Great job, I myself prefer to use a extra mouse rather then the built in one, if you chose to do this it wont work right away but if you give it a moment to recognize the mouse it will then be functionable.
