Maybe I can find the manual on Gateway's site.

Here's the link to your stuff:

Go to the User Guides tab. Get the ones you want. In typical Gateway
support fashion, all the zip files are the same name, so change the name
as you download, or unzip them one at a time, then overwrite the first
zip on the next download.

I'm sorry I misled you on the Fn key to disable the touchpad; I was
helping someone else with their NV laptop, and that was the manual I was
looking at, not yours.

To answer your other question about the driver installation, you really
don't have a full driver installed, or the touchpad would show in
Control Panel, whether under the Mouse item or Synaptics itself. You're
basically running the generic Windows 7 touchpad driver, which is
probably why it's not showing up anywhere. By installing the Gateway
driver, you'll have the option to enable/disable it, adjust the
sensitivity, scroll speed, etc., just like you can with a real mouse.

I have an MX6453, but I guess 6450 is close enough. I don't see
anything in either manual about disabling with the keys. They seem to
have missed Scroll, Pause, Ins,Del.
