Hi there!
My dell latitude 3510 died, burnt chipset, so i bought a new mainboard, the laptop seems to works ok with the new mainboard but the problem that im facing is: the manufacturing mode active press ALT+F , the warning message is The service tag has not been programmed, so i tried to add the original tag of my laptop in the new mainboard throught the bios setup with no luck.
