Hmmm
If its really that much work just trying to figure it out NOW before you've purchased it... you're willing to support this product for the next few years?
You can't even get the OS installed!
IMO it sounds like too much labor, cut the losses and move on to the next product. Either that or contact the reseller, if they really want to sell 80 laptops they should be willing to do whatever they can to help you out.
If you're buying 80 laptops you don't want to stress just to get ONE working.
Sorry can't help regarding the actual laptop but a suggestion just the same
