Changing HP motherboard system IDs

When performing a motherboard swap in an HP system, to ensure proper system functionality, the system IDs will need to be reprogrammed from the product SKU label(s) on your system. 
 Entering the BIOS / UEFI on your replacement HP system board and then going to system IDs will normally only reveal three or four fields, instead of the full 7 or more fields you may need to populate. 
 To access the additional system ID fields, when going to the sub-menu that has “system ID”, hit CTRL -A before entering the system ID section to expose the additional fields.
