Recently I bought a CNC plasma cutter from ebay. I drove 400 miles to pick it up and the guy who sold it to me gave me a whole bunch information on the dell latitude laptop that came with it. I asked if all the passwords were there and he assured me that they were all written down. So I brought it home it took me a while to get it set up, but finally I did. but when I tried to log onto the computer the password he gave me did not work. I have tried everything, I called him back ten times and all the passwords he gave me did not work. He said his son set it up and he would call him but now he is not taking my calls. I would really like to use this computer, it supposedly has MACH3 installed on it which I need for the CNC controls and there are a couple of CAM and CAD systems that I need too. plus the computer has the copier connection in the back for the driver. So to replace it I would need to buy another computer with the copier port and then about $500 dollars worth of MACH3 and CAD software. I have tried the F8 function for the reset but there is no "repair my computer" option available. I have looked into buying a setup disk but I don't know what exactly what to buy, plus it would erase the programs that are installed. I have tried all kinds of admin password resets from the F2 function but nothing seems to work. I called a repair place and they said there was nothing they could do because they do not know if its stolen. Any help would be appreciated.
