I'm not sure if this just affects Gateway laptops or if all laptops are subject to this issue.  On a laptop even when the correct mouse drivers are installed you are not able to set all mouse properties.

One of the annoying ones is the "lines to scroll" for each mouse wheel rotation.  It defaults to a very annoying low amount of 1.  This is not very good at all.

To get around this you can use the TweakUI powertoy from Microsoft to change the lines per scroll.  Download the powertoy then open it, go to the Mouse branch then Wheel, make sure Use mouse wheel for scrolling is checked and then choose the Scroll by X lines at a time where X is the number of lines you want to scroll.
