Hello

Just wanted to let you know an easy way to disable touchpad on Asus K53S. As some of you have discovered the use of Fn+F9 doesn't always work.
And sometimes one wants to disable touchpad only when using a USB-mouse.
Disabling mousedriver will permanently disable touchpad untill you enable it again. But that requires som clicking and fixing every time the touchpad is unwanted/wanted.
I discovered a way of disabling the touchpad only when USB-mouse is connected;
Open Control Panel, and type "mouse" in the upper right search corner.
A menu with different mouse-choices appears. Click on the header which says "Mouse".
Now you get a window with 5 tabs. The fifth tab (all to the right) will open a menu of your smartpad (touchpad). (Mine says "Elan", but this can probably be different on some machines.)
In this tab you get a choice that says: "deactivate when USB-mouse is plugged in" (or something simular).
When checking this choice you get a smartpad that automatically disconnect when you want to use a USB-mouse.
Hope this was helpful
