manufacturing mode? no bios loading? help

i just soldered on a bios password chip successfully, but when i now power up the laptop there is about a 20 second (havent counted it) time where nothing happens just the lights turn on. i assume this is where the computer is searching for the bios and then after that the cpu fan starts, the dell bios loading screen comes up with nothing loaded and it quickley switches to manufacturing mode and tells me to get it out of manufacturing mode, press Fn-X when i do this nothing happens. then it goes to the administrative password screen and i just push enter and it works i guess that is what the chip was supposed to do? after this it switches back to manufacturing mode and then goes to windows. windows runs fine except the mobo speaker makes noise whenever i push a key.

please help, thanks a lot
