Unfortunately, that will not work on my Inspiron, because the "Touchpad Settings" tab is non existent in that area of the control panel.
There is a tab labeled "Dell Touchpad". When I click on the tab, there is a picture of the touchpad, and below it is some text that says "Click to change Dell Touchpad settings". When the text is clicked on, it opens a program called "Pointing Devices", that seems to be separate from the control panel.
I have tried searching through this program to find the option to enable the touchpad while typing, but have had no luck.
