Enabling/Disabling the Touch Pad
You can enable/disable the touch pad on your VAIO computer.
Press and hold down the Fn key and press the F1 key.
Each time you press the keys, the touch pad is enabled/disabled.
Be sure to connect a mouse before disabling the touch pad. If you disable the touch pad before connecting a mouse, you will be able to use only the keyboard for pointing operations. (Non touch screen equipped models)
