When I first started using my HP G42, I kept accidently disabling the touchpad by tapping the led at the top left of the touchpad. I found a way to "disable" the disable zone in a registry change, I think. I thought I saved the link for the directions, but I must have deleted it....When I attempt to change the Device Settings in Synaptics Pointing device settings, the touchpad disable zone settings is checked, but is "ghosted" and I am unable to change the setting. I now use a wireless most most of the time and would like to have the tap zone active again.
I know the led still functions, because if I choose to to disable the toiuchpad when a mouse is attatched, the led comes on, to indicate the pad no longer will accept input.
Any help would be appreciated.
Reinstalling the synaptics driver does not work....changing the bios does not work... a system restore would change all kinds of setttings, and I'm not sure I have any restore points that are old enough,anyway.
I'm fairly sure there is some kind of software switch or registry setting to fix this.
