Motherboard Serial number not changeable

I replaced the motherboard in this unit for a client. Only issue is i can not get it to stop coming up with the 2200 error. Which is i need to enter the model and serial number in the bios. From what i can see is only lenovo has software to do that. Does anyone have any similar experinces?
