I wasn't entirely sure where to put this thread.. but I'm at a loss. I work in a computer repair shop, and this is something I've done time and time again, but I'm hitting a wall this time. My customer came in with a Dell Inspiron 5759 with a fried motherboard. I put in the new board, punched the service tag into the bios of the new board, and did the ALF+F reset in the bios to kick it out of manufacturing mode.. but I can't get it to stick. Every time, it boots normally, but as soon as I shut it down, it reverts to manufacturing mode again.
