Model Latitude 5450 error code 3 ember 5 white or power rail fail resolved

Power fail fail or 3 amber 5 white error code is mother boards issues resolved for one zero ohm's resistor, yes resolved for zero ohm's resistor,  this resistor working like fuse,resistor open or defect voltage drops 8.5v Or 9v for PU601 location core IC component, after change this zero ohm's resistor mother board working normally , NOTE:this is only solution for latitude 5450
