Ain't that weird?
I'm sitting here with my 11 yr OLD Dell Latitude, ON, and running Windows 8.1/Pro/32, and when I installed 8.1 on it, the driver for the Touch Pad was automatically installed. NO Problemo! Likewise on my other seven laptops, where three of them are Dells, of varying model and age.
The driver pack that comes with Windows 8.1 Pro, is truly amazing. It even installs workable drivers for my Epson XP-410 printer *, and my PCIe USB 3.0 card.
* (if it's connected and turned ON during the install)
So I'm wondering about that 8.1/Enterprise version of Windows. Did that come from MS or a 3rd party?
Is it even possible, in your BIOS, to turn off the Touch Pad. I've never seen that, but anything is possible.
I know that some PC's even have a switch above the Touch Pad that will disable the Touch Pad.
Were that laptop one of mine, I might even try a RE-Install of 8.1, after backing up my current install, just to see if that would fix the problem.
In the not so distant past, I've installed Windows 8.1 and had something like the time zone, get really screwed up during the install, and only a re-install would fix that problem.
Good Luck to you
