I see there is Latitude 10 or Latitude ST2E tablets. What is the difference? I see there is a BIOS update version A04 for the Latitude 10. There is a BIOS update version A03 for the Latitude ST2E.

I have a Latitude 10 which came with windows 7 pro and the wireless worked perfectly fine but I stupidly upgraded the tablet to windows 8 pro and now it is telling me that there is no supported wireless card installed.

Thanks for quick reply. And what should I notice / care about if I decide to buy online. I heard that I must use same mHz speed for both RAMS. Wouldnt more than 4GB work in 32bit UBUNTU 12.04 ?
