I've got notebook AMILO Pa 1538. I want to disable my touchpad, but perhaps my driver doesn't support this operation, because in device manager i can't select "disable" mode for touchpad.
In the german forum two users wrote that they are using the Synaptics driver: http://www.synaptics.com/support/drive.cfm It's an AVC touchpad, but this one seems to work and it's possible to deactivate the pad.
